Alan Lowe -- President and Chief Executive Officer

Thank you, Jim. Good morning, everyone. Before my comments on our business, I will start with the sad news we communicated in the press release yesterday. We recently learned that our board chairman, Marty Kaplan, passed away.

Marty in his role as chairman was a trusted and wise advisor, but he was much more than that. He was a friend, a truly amazing human being who will be greatly missed. On behalf of Lumentum, we send the Kaplan family our most heartfelt condolences and sympathy. I will now move on to my comments on the business end markets.

The fourth quarter was eventful to say the least, but it capped off at fiscal year during which we made significant progress toward our long-term strategic and financial goals. During the past year, we believe we have added to or extended our market and technology leadership positions in telecom and 3D sensing. We introduced many highly differentiated new products and one new design win with market-leading customers in all of our markets. In our commercial lasers business, unique new products enabled us to grow revenue to new record levels in a down market.

The Oclaro acquisition has given us a first-mover advantage in a transforming industry. First, we attained a leading position in telecom transmission based on fundamental indium phosphide photonic integrated circuit technology. We believe this technology will be critical to our customers' ability to scale to higher network bandwidth in the future, including 800 gigabits per second, and eventually higher speeds. Second, we revectored our datacom business to a significantly more profitable model that is based on a highly differentiated photonic chip capability.

We expanded our datacom market focus to include 5G wireless and other high-volume applications. And finally, we improved our business model by achieving cost synergies on a more accelerated time line than originally estimated and are now increasing our annual synergy target to $100 million from our initial $60 million target, which we have exceeded. These additional savings will be attained over the next five quarters. Over the past year, we have seen a trend toward further industry consolidation.

Several other M&A deals in our space have been announced to date. There are perhaps more to come as market participants recognize the need for scale. Fiscal-'19 revenue was at a new high, exceeding $1.5 billion and was up 25% relative to the prior year. For the first time, full-year operating margin expanded to more than 20%.

I believe these results and accomplishments both underscore the significant progress we have made toward our strategic goals during fiscal '19 and position us well for revenue growth and margin expansion in fiscal '20 and beyond. I'm proud to lead the best team in the industry and one that customers continually turn to first for the photonics technologies they need to win. Before turning to more details on our results, I'd like to provide an update on our business with Huawei. On May 20th, we indicated we had stopped shipping to Huawei in response to their addition to the Entity List and to become compliant with U.S.

Department of Commerce requirements. Subsequently, we completed a detailed analysis of the products we supply to Huawei and determined that certain products were not subject to export administration regulations. We resumed shipments of these products late in the quarter after putting in place new business processes to ensure compliance with government requirements on an ongoing basis. We intend to fully comply with U.S.

Department of Commerce requirements. Sales to Huawei were down 25% sequentially in the fourth quarter as a result of these actions. Looking to the first quarter, we expect sales to Huawei to be flat to down sequentially. As you can imagine, the very dynamic nature of the current geopolitical situation adds to the challenges of projecting future Huawei revenues.

Now for details on the fourth quarter and full fiscal-year performance. Telecom revenue was up 65% in fiscal '19. Within telecom, transport revenue increased by nearly 50%. In the fourth quarter, telecom revenue declined 6% sequentially due to lower shipments to Huawei.

Partially offsetting the Huawei decline was growth in other customers. Despite the geopolitical disruption during the fourth quarter, we again achieved record ROADM revenue. We were able to partially offset lost Huawei ROADM revenue in the quarter through sales to other customers after we redirected manufacturing capacity to them late in the quarter. Fourth-quarter revenue from coherent transmission modules was up 10% sequentially, with sales of both ACO and DCO products growing.

Looking to the first quarter, we expect telecom revenue will be flat to up sequentially. Telecom customer demand outside of Huawei is strong. However, this demand is for different mix of products than Huawei purchases from us and for which our supply chain had been driving material. Challenges in obtaining supply of long lead-time materials is currently the limitation.

Additionally, impacting telecom is an expected temporary dip in our submarine business, which has historically been a lumpy project-based business. Looking further out, based on expected continued strong growth and global network bandwidth and data center traffic, the needed optical infrastructure for 5G wireless, we believe that telecom market should be strong on a multi-year basis. We believe the strength we have seen in telecom transport over the past year is a leading indicator of future strength and demand for transmission products. We are well-positioned to capitalize on these market trends with our industry-leading telecom transmission and transport products and deep customer relationships.

We benefit from global bandwidth expansion regardless of who builds or supplies the networks. Our next-generation products, including MxN and high-port count twin ROADMs; DCO modules, including ZR and longer reach; and high baud rate indium phosphide components, including those for 800 gigabits per second, are critical to our customers' global -- our global customer base. Turning to datacom. Early in the fourth quarter, we closed a previously announced divestiture, our Japan-based datacom transceiver business.

This was a key milestone in our strategic pivot to focus exclusively on photonic chip sales in the datacom market and exit the challenged datacom transceiver business. Since the announcement of this transaction, we have seen strong engagement from customers for datacom photonic chips, including in 5G wireless applications. This drove fourth quarter datacom chip sales up 11% sequentially to new record levels. In many cases, new customer interest is from leading competitors who previously would not purchase from us due to the competitive nature of the transceiver -- us competing in the transceiver business.

As a reminder, we are discontinuing all remaining datacom transceivers and certain low-margin telecom product lines. Revenue from these product lines totaled $31 million in the fourth quarter and should decline to zero over the next few quarters. Turning to our industrial and consumer product lines, which includes 3D sensing. Fourth-quarter revenue was up 13%.

This growth was larger than our prior guidance for both industrial diodes and 3D sensing lasers. In the case of 3D sensing, in the fourth quarter, we started ramping deliveries to customers -- to support customers' product cycles expected to start this fall. We expect unit growth to exceed price declines as 3D sensing is expected to be incorporated in a higher percentage of end customer models, and supply chain inventory levels appear to be more normalized when compared to last year. Taking into account the accelerated fourth-quarter shipments and expectations around global smartphone volumes and our market share, we expect 3D sensing revenue in the first half of fiscal '20 be slightly up from the first half of fiscal '19.

We continue to make good progress on 3D sensing customers worldwide, including in world-facing applications. Favorable consumer and media reviews for initial world-facing-enabled smartphones has caused customers' product road maps to more broadly incorporate 3D sensing -- 3D depth sensing for photography and augmented and virtual reality applications. Based on customer activity, we expect major smartphone manufacturers to introduce products with new world-facing capabilities in calendar '20. This, combined with increased customer demand for smartphones driven by future 5G availability, should drive a significant increase in 3D sensing market in calendar '20 and '21.

We are very well-positioned for this growth -- growing opportunity. Customers around the world know they can count on our proven and unrivaled reliability and volume capability. We have shipped hundreds of millions of devices with unmatched performance, quality and reliability, and expect to exceed a half a billion cumulative devices shipped by the end of our first quarter. This experience is a valuable advantage and is difficult for our competitors to replicate.

Turning to commercial lasers. As highlighted earlier, new products enabled us to grow fiscal-'19 laser revenue to new record levels in a down market. This growth was driven by a nearly 100% increase in fiber laser sales relative to the prior year. In the fourth quarter, our commercial lasers segment revenue was down 13% quarter on quarter as expected.

Our commercial lasers business is important to our long-term strategy. It provides us a significant addressable market to grow into while leveraging our core set of optical technologies and manufacturing capabilities. Further, it provides us a level of customer and end market diversification. Looking to the first quarter, we expect lasers revenue to soften further as we enter the seasonally weaker fall-time period.

However, based on customer requests for quote activity, we believe the commercial lasers market will return to growth in the new calendar year. Over the long run, because of our investments in unique new products and technologies, we believe we have good opportunity for growth, driven by new product introductions in addition to market growth. Throughout my remarks, I've highlighted the significant progress we have made toward our strategic and financial goals during fiscal '19 and how we have positioned ourselves well for fiscal '20 and beyond. This, combined with the growth catalyst we see in each of our major product lines, makes it a very exciting time at Lumentum for all stakeholders.

At Lumentum, we are releasing the power of light to create a brighter future. With that said, I will now turn the call over to Wajid.

Wajid Ali -- Chief Financial Officer

Thank you, Alan. Good morning, everyone. Before jumping into our fourth-quarter results and our guidance for the fiscal first quarter of '20, I'd like to run down our full-year fiscal-'19 results. Net revenue for fiscal '19 was $1.57 billion, up 25% compared with fiscal '18.

Fiscal-'19 optical communications segment revenue was up 29%, driven by strong market demand for telecom products and the Oclaro acquisition. Our laser segment revenue was up 4% compared to the prior year, driven by strong fiber laser sales. For the full year, GAAP gross margin was 27.2%, GAAP operating margin was negative 1.4% and GAAP diluted net loss per share was $0.54. These GAAP results include the impact of restructuring, writedowns, amortization of intangibles and other charges related to the acquisition and our actions to attain acquisition synergies.

Full-year fiscal-'19 non-GAAP gross margin expanded 60 basis points to 39.5%, driven by higher levels of higher-margin products in our revenue mix, as well as overall increased leverage over our fixed manufacturing costs. Non-GAAP operating margin expanded 80 basis points to 20.5% for the full year, and non-GAAP net income increased more than 23% relative to the prior year, resulting in non-GAAP diluted net income per share of $4.25. We ended the year with cash and short-term investments of $769 million, an increase of $71 million relative to the prior quarter. Now turning to the fourth quarter.

Net revenue for the fourth quarter was $404.6 million, which was down 7% sequentially due to lower sales to Huawei and the expected decline in lasers. GAAP gross margin for the fourth quarter was 21.5%, GAAP operating margin was negative 3.4% and GAAP-diluted net loss per share was $0.34. Again, GAAP results include the impact of restructuring, writedowns, amortization of intangibles and other charges related to the acquisition and our actions to attain acquisition synergies. Fourth-quarter non-GAAP gross margin was 38.9%, which was approximately flat sequentially on lower revenue levels.

Non-GAAP operating margin for the third quarter was 19%. Non-GAAP operating expenses totaled $80.7 million or 19.9% of revenue. R&D expense was $46.4 million. SG&A expense was $34.3 million.

I think it is important to highlight here that synergies achieved to date through the fourth quarter helped drive a sequential 120-basis-point expansion in operating margin despite a 7% sequential decline in revenue. Non-GAAP net income was $70.8 million for the fourth quarter and includes $2.4 million of net interest expense and tax expense of $3.5 million. Non-GAAP diluted net income per share was $0.92 based on a fully diluted share count of $77.1 million. Now turning to segment and product-line details.

Optical communications segment revenue was $356.8 million, which declined 6% sequentially. Within our optical communications segment, telecom revenue at $227.7 million was down 6% sequentially due to lower Huawei sales. Datacom revenue at $41.5 million was down 28% sequentially, driven by the transceiver product-line divestiture. Industrial and consumer revenue at $87.6 million was up 13% sequentially due to higher industrial diode and 3D sensing revenues.

Optical communications segment gross margin at 38.3% increased 30 basis points sequentially on lower revenue due to the divestiture of lower-margin datacom product lines and higher industrial and consumer in the mix. Our laser segment revenue at $47.8 million decreased 13% sequentially. Fourth-quarter lasers gross margin was 43.5%, a decrease of 250 basis points due to lower revenue. From the close of the Oclaro transaction through the end of the fourth quarter, we have taken actions that when annualized, achieved more than $60 million in synergies, which is the target we put forward when we announced the transaction.

We achieved these synergy levels earlier than we estimated when we announced the transaction by strong execution after the close of the transaction. We are not yet done on the synergy front, however. We now estimate that synergies will be approximately $100 million in total or $40 million higher than our original target. Additional synergies will primarily benefit cost of goods sold as further operating expense synergies are likely to be reinvested in new capabilities and R&D programs to fuel growth and extend our market leadership positions.

We expect to complete the additional synergy actions over the next five quarters, although the bulk of these positive financial impacts will be realized toward the tail end of this time line. We continue to target the financial model announced at the time of the transaction. We believe these additional COGS synergies should drive average gross margins to the upper half of the 40% to 45% gross-margin range of the target model. Now on to our guidance for the first fiscal quarter of fiscal '20.

The projections we are providing today are on a non-GAAP basis and are based on our assumptions as of today. We project net revenue for the first quarter to be in the range of $435 million to $455 million. This revenue projection includes telecom being approximately flat to slightly up, datacom declining as we continue to wind down transceiver sales, commercial lasers decreasing approximately 20% driven by the factors Alan mentioned earlier and industrial and consumer increasing as we enter the seasonally strong time period for 3D sensing. We project first-quarter operating margin to be in the range of 22.5% to 24.5% and diluted net income per share to be in the range of $1.12 to $1.26.

These projections incorporate an approximate share count of 78 million. With that, I'll turn the call back to Jim to start the Q&A session.

Jim Fanucchi -- Managing Director and Head of West Coast Operations

Yup. Thank you, Wajid. I'll turn the call over to the operator to start the Q&A session. [Operator instructions] Operator, let's begin the question-and-answer session.

Questions & Answers:


Operator

[Operator instructions] The first question comes from the line of Alex Henderson of Needham.

Alex Henderson -- Needham and Company -- Analyst

Hey, first, a clarification. You said that 3D sensing would be up slightly from the first half of '19, but I'm not sure whether you meant the first half of ' 19 fiscal year or first half of '19 calendar year. Could you clarify that, please?

Alan Lowe -- President and Chief Executive Officer

Yeah. We were talking first half of fiscal year compared to the first half of fiscal year.

Alex Henderson -- Needham and Company -- Analyst

Great. That's what I thought.

Alan Lowe -- President and Chief Executive Officer

In the next six months, we expect to be -- but to slightly up from the first six months of fiscal '19.

Alex Henderson -- Needham and Company -- Analyst

Perfect. Second question, if I could. The Huawei stuff obviously is top of mind. Have you asked the government for any exclusions relative to Huawei? And has the 3D sensing piece been included in the ban so far? Or is that something that might be allowed to ship in at some point?

Alan Lowe -- President and Chief Executive Officer

Yeah. I think as I said, we've really developed a new process to make sure we comply with regulations. The majority of our products are not subject to EAR across the board with respect to being allowed to ship. So I don't want to comment on specific products, but I would say that the vast majority of our products are not subject to EAR.

Alex Henderson -- Needham and Company -- Analyst

OK. And if I could ask one more question. How long do you think the supply constraints on telecom will be evident? And is that a matter of just simply shifting the type of product that you're producing as a result of any shifts in production? Or is that something that you think will last well into the back half of the year and then maybe even into next year? Can you give us any time line on that? Thanks.

Alan Lowe -- President and Chief Executive Officer

Yeah. I certainly expect us to be able to solve the supply constraint over the next several months. It is impacting this quarter and into a bit of Q2, but we've got a whole focus on making sure that the gating material items and suppliers are being coached to help us, and I'm sure we'll make progress. But it is impacting this quarter and the beginning of next quarter.

Alex Henderson -- Needham and Company -- Analyst

Super. Thank you very much.

Alan Lowe -- President and Chief Executive Officer

Thanks, Alex.

Operator

[Operator instructions] Your next question comes from the line of Samik Chatterjee of J.P. Morgan.

Joe Cardoso -- J.P. Morgan -- Analyst

Hi, this is Joe Cardoso on for Samik. My first question come -- is related to 3D sensing guidance. You guys kind of seem more bullish in terms of 3D sensing ramping into this -- well, your fiscal first half. Can you just provide us an update on whether you're seeing that coming from your largest customer or whether that's more optimism around adoption from the Android camp?

Alan Lowe -- President and Chief Executive Officer

Yeah. We're not going to talk specifically about customers, but I'd say that we've been working on new product design wins across the board, both with our largest customer, as well as Android. And I'd say that we're -- based on where we are today, we expect a good first half of the fiscal year. That said, I'd say that we weren't expecting as much growth as we saw in the fourth quarter, and we think that that is a bit of a result of earlier ramp of new products for the fall, but we still believe that the inventory levels are in a better situation than they were a year ago.

So that gave us confidence that the first half of fiscal year is in pretty good shape.

Joe Cardoso -- J.P. Morgan -- Analyst

Got it. And then relative to your gross -- your long-term target of being in the upper range of your gross-margin target, is that -- so clarification, is that largely coming from the synergies? Or is that kind of coming from the mix of business that you guys are seeing?

Wajid Ali -- Chief Financial Officer

Yeah, hi. It's Wajid here. It's a little bit of both. We're seeing favorable product mix across our product lines, and we're expecting that to continue over the next number of quarters.

But in addition to that, it's the $40 million of annualized synergies that we expect to flow through in the tail end of that five-quarter period that will really help us and give us confidence in moving up the range of 40% to 45%.

Joe Cardoso -- J.P. Morgan -- Analyst

And just a clarification on the synergies, where exactly are you guys seeing the upside to the synergy targets?

Alan Lowe -- President and Chief Executive Officer

Well, I think across the board, I think we've made some decisions more rapidly and executed more rapidly than we had originally advertised, and that's why we were able to get the full $60 million done already. I'd say looking forward, we still have some product rationalization to take place, as well as in my prepared remarks, I talked about some of the lower-margin telecom products exiting over the next several quarters, and that, along -- that kind of drags along a bunch of fixed costs in fabs that are going to go away during that time period. So I think it's a combination of really focused on how do we streamline our manufacturing processes, how do we combine our ERP system, which is not done and will be done later this fiscal year. So it's a combination of those things that give us confidence that there's another $40 million to go.

Wajid Ali -- Chief Financial Officer

Yeah. Just to add to that, I mean, we've got -- just like with the first $60 million, we had clearly defined actions with time lines and a bottoms-up. It's the same with the next $40 million. We've got a bottoms-up with clearly defined time lines and actions that we're following, which is why, Alan mentioned earlier, we've got a lot of confidence around achieving it.

Operator

Your next question comes from the line of John Marchetti of Stifel.

John Marchetti -- Stifel Financial Corp. -- Analyst

Thanks very much. Just wanted to get back to your comments about an expected sort of mix shift here in the telco world as you continue to move at least over the short term away from some of the Huawei mix. Should we think of ROADM sales maybe moderating some of that growth as we're looking at, certainly, the first half of this fiscal year but maybe on a full-year basis as well?

Alan Lowe -- President and Chief Executive Officer

Well, I think our expectation, given where we are today, is that ROADMs, regardless of our guide and our expectations with Huawei, continue to grow. So we're expecting ROADM growth in the first quarter and continued ROADM growth as we introduce new products and new design wins across our customer base globally. So I think our expectation -- and we still are adding capacity, especially for the new leading-edge MxN products, as well as the very high port count, which has broad adoption across our customer base. So we're expecting another good year for ROADM.

John Marchetti -- Stifel Financial Corp. -- Analyst

And then maybe just to follow up to Alan on the comments that you made around submarine, that being a little bit lumpy for you at least in the first half of this fiscal year. Is that a change in customer behavior there? Is it a sign that you're starting to see customers either move away from new builds into upgrades or vice versa? Just curious what you're seeing in that submarine market as it's been relatively strong for the industry here for quite some bit.

Alan Lowe -- President and Chief Executive Officer

Yeah. I think it's a combination of a couple of things, one of which is it is lumpy, it's project-based. We -- if you recall, we made most of our submarine products at our contract manufacturer in China. We ramped up production in order to make the transition to our own Thailand facility, and that is coming up in Thailand.

So I'd say it's a combination of two things. One is project-based and lumpy. We had a really strong quarter in fiscal Q4 on submarine, and I think part of that is a result of us winding down production in one location and moving it to bring up in a new location, and that takes some time. So I think there probably was some inventory taken in Q4 that it's going to be consumed over the next several months and quarters, and then bringing up the new facility on submarine takes time.

And so we're on track with the bring-up, but I'd say that this quarter is just going to be a low quarter for submarine due to those factors.

Operator

Your next question comes from the line of Meta Marshall of Morgan Stanley.

Erik Lapinski -- Morgan Stanley -- Analyst

Hi, this is Erik on for Meta. Thanks for taking our question. Maybe just first, on the lasers business, what is the timeline for adoption of the product outside of the model now that there's a bit more capacity? Could you see revenue in second half of fiscal '20?

Alan Lowe -- President and Chief Executive Officer

Yeah. I mean we are winding down the completion of the development-specific products for other customers and have shipped samples. So I wouldn't expect any meaningful revenue in the first half but expect it to contribute in the second half of the fiscal year.

Erik Lapinski -- Morgan Stanley -- Analyst

That's helpful. Thanks. And then on the datacom chip sales, could you maybe give us a sense on just the size that you would hope to achieve in that business over the next 12 months?

Alan Lowe -- President and Chief Executive Officer

I think it's -- today, quite frankly, we are constrained by our ability to produce more wafers and more chips. We have demand that is not being satisfied, and we're making investments to handle that demand. I think with what's going on fundamentally in data centers and hyperscale build-outs and 5G, the demand for unit volume is growing rapidly, and we expect to really be able to, over the longer term, double that business, and I don't see any reason that we can't do that.

Erik Lapinski -- Morgan Stanley -- Analyst

Thank you. And then just finally on Huawei. If a waiver were to be granted for kind of those outstanding products that aren't shipping, is that something that you would start filling products immediately? Or is there a bit of a lag in time line to start resuming shipments?

Chris Coldren -- Senior Vice President of Business Development

Yeah. There would be a -- probably a bit of a lag only in that if we're unable to ship a product today, we're not going to be building product continually. We do have some inventory so we respond, but we do typically have manufacturing times that can be up a quarter in length, and therefore, there's some delay.

Operator

Your next question comes from the line of Tejas Venkatesh of UBS.

Tejas Venkatesh -- UBS -- Analyst

Thank you. What sort of ASP declines do you expect in VCSELs for fiscal '20 versus '19?

Alan Lowe -- President and Chief Executive Officer

Yeah. We're not going to get into specifics on that. I think what I will answer is that we expect, with world-facing coming on board in a meaningful way in calendar '20 and with a new set of chips that we believe will be introduced in calendar '20, we will have an ASP reset or a content per device will increase in calendar '20, we believe, in a meaningful way. I think our expectations and what we tried to say in the prepared remarks was that unit growth would be higher than ASP reduction, therefore, driving growth in our first half of fiscal '20.

But I think calendar '20 is going to be a very solid year for us in 3D sensing because more content per phone and new devices that will go into handset or mobile devices.

Tejas Venkatesh -- UBS -- Analyst

Thank you. And as a follow-up, I wanted to revisit ROADMs. What was ROADM revenue in 4Q? I believe you had $130 million per quarter of capacity. So it sounds like you're still adding capacity.

So just an update on that would be great. Thank you.

Chris Coldren -- Senior Vice President of Business Development

Yeah. Hey, Tejas. We're not disclosing revenue by product line. I think you can imagine, triple-digit number, and we grew quarter over quarter, did not grow as much as we had originally anticipated prior to mid-May.

But as we redirect our manufacturing capacity, we expect to grow more strongly in ROADM going from [Technical difficulty].

Operator

Your next question comes from the line of Troy Jensen of Piper.

Troy Jensen -- Piper Jaffray -- Analyst

Hey, thanks, and congrats on a really nice results here.

Alan Lowe -- President and Chief Executive Officer

Thanks, Troy.

Troy Jensen -- Piper Jaffray -- Analyst

Hey, Alan, maybe for you. I'd love to get your thoughts on the Acacia-Cisco deal. I mean, clearly, Cisco is a big ACO customer for you and Oclaro with the intention, I'm sure, to get to the DCOs. And just thoughts on what this means longer term with that customer.

And then also, were you guys one of the bidders in the Acacia transaction?

Alan Lowe -- President and Chief Executive Officer

Well, we're certainly not going to comment on the second part of your question. But --

Troy Jensen -- Piper Jaffray -- Analyst

I had to try.

Alan Lowe -- President and Chief Executive Officer

Yeah. Well, our perspective on the deal is it's a good deal for everyone involved. I mean Cisco has been a longtime partner and customer of ours and a solid -- really strategic customer of ours. Acacia has been a supplier to us, a customer to us and a competitor to us.

I think the transaction has a couple of dynamics, one of which is customers are going to want a second source, and we've seen activity increase with respect to DCOs since the announcement from Lumentum. And I think that Cisco is going to continue to be both a transport and transmission customer of ours into the future. So all of that said, I think it's a very positive outcome for the industry and a positive outcome for Lumentum because I expect fully to be continuing to be a supplier to Cisco and to Acacia, and we believe that the dynamic will be a catalyst for growth for us on DCOs and ZRs in the future.

Troy Jensen -- Piper Jaffray -- Analyst

OK. And maybe just a question on opex. I understand there's more synergies, but I mean just specifically looking at the September numbers here, is opex, on an absolute dollar basis, going to be declining sequentially, already get to this range? Or is it just going to be a bigger spike in gross margins?

Wajid Ali -- Chief Financial Officer

Yeah. Hi, it's Wajid here. We'll probably see opex stay within the range of fiscal Q4 plus or minus a couple of million dollars. You'll really see the synergies start flowing through, like we said on our prepared remarks, within the gross margins but more in the latter part of the five-quarter time line that we provided.

This upcoming quarter, gross margins obviously will be higher because we've got a stronger mix of 3D sensing. But outside of that, the synergies that we talked about that are in addition to the $60 million we already achieved will be primarily in our cost of goods sold line. So opex will stay relatively flat plus or minus based on the investment levels we make and the timing of those investment levels.

Operator

Your next question comes from the line of Rod Hall of Goldman Sachs.

Rod Hall -- Goldman Sachs -- Analyst

Yeah. Hi, guys. Thanks for the question. I wanted to ask about the ROADM demand situation.

So I know that you had said previously that in the September quarter, you expected to serve a bunch of backlog that you had in terms of orders, and so I'm assuming that that's being done. And I wondered, beyond the September quarter, is -- now that the backlog is cleared, or maybe you can clarify whether it will be, what the demand situation looks like. I think, Alan, you had alluded to some growth there, but I just wanted to clarify what that ROADM demand looks like on an organic basis as we get into the December quarter and beyond.

Alan Lowe -- President and Chief Executive Officer

Yeah. So demand for ROADMs across all of our customer base is very strong. We are not satisfying the overall demand in the September quarter, and we'll see how it goes in the December quarter as we add more capacity. But I'd say that the capacity is not interchangeable in every case in that like our MxN is a unique capacity that's not shared with other product lines.

And then the mix between modules or blade changes dynamically through the quarters. So that's why it gives us confidence that the September quarter ROADMs will grow. I would have every expectation that the December quarter ROADMs will grow as well, assuming we have the right capacity for the mix that comes through. And we are seeing a shift to continue higher port count when one by two by 35 and MxN, as well as blades associated with this newer technology.

So we're going to continue to grow our ROADM capacity and our ROADM revenue.

Rod Hall -- Goldman Sachs -- Analyst

So, Alan, just to clarify that, are you thinking there's a good chance that in December and beyond, the ROADM supply will still be short of demand or you think that by the time we get in the December supply chain, at least equal demand, assuming you've been able to reconfigure production the way that you need to?

Alan Lowe -- President and Chief Executive Officer

Well, I think, again, it's going to be based on the mix we get. And as we continue to be working with our customers across the globe, our new designs for the high-capacity and contentionless and directionless ROADMs, we believe that those will continue to be constrained for some period of time until we bring on additional new capacity. So we're trying to tighten the capacity to get some flexibility, but we continue to be more demand than our customers are forecasting in the longer term. And it takes a while to add the capacity.

We are bringing on more capacity, but again, we're having to anticipate that mix. But today, I'd say we don't have any excess capacity in any of our product lines on ROADMs. So we're feverishly trying to get more out of the existing capacity, drive yields, drive productivity and drive output without having to add a bunch of capacity.

Rod Hall -- Goldman Sachs -- Analyst

OK. And then on the second kind of major question we had was on lasers gross margins, those were down quarter over quarter, and I know you guys are targeting 50%. Could you just comment on that margin trajectory and what you're thinking now in terms of how that progresses toward that 50% goal?

Alan Lowe -- President and Chief Executive Officer

Yeah. I mean I think the drop we saw in the June quarter was really volume-based and revenue-based, and there are some fixed costs that don't get absorbed with lower volume. I think as we expect in calendar '20, the volume will pick back up. And as we introduce new products from new fiber lasers to new ultrafast lasers, we expect that we will go closer to the higher 40% margin and could get to 50% margin in calendar '20, assuming the mix is right and that the economy allows us to really grow that business.

That said, I'd say the lasers competitors of ours are hitting some pretty heavy headwinds. And so I think we bought the trend, as we said, by growing our lasers business in a pretty tough environment. But we expect that calendar '20 will be a different story.

Chris Coldren -- Senior Vice President of Business Development

Even amplify that over the past year, a lot of the growth in lasers -- fiber lasers, which historically for us were below our lasers average margin given there -- over the past year, become a substantial portion of it, but the lasers mix and gross margins have increased. Up until now, with revenue coming down, it's compressing margins. But I think the point I'm trying to emphasize is that the nonfiber laser portion has had a pretty brutal year, but it's a higher margin than average. So as Alan alluded to calendar '20, we believe nonfiber laser portion will begin to rebound, and that will have a very positive influence on the mix and, therefore, margin.

Your next question comes from the line of Simon Leopold of Raymond James.

Mauricio Munoz -- Raymond James -- Analyst

Thank you for taking my question. This is Mauricio in for Simon. A quick housekeeping item. Can you please give us the number of 10% customers this quarter and the present contributions, please?

Chris Coldren -- Senior Vice President of Business Development

We had three 10% customers. I don't think we're releasing that in our press release today.

Alan Lowe -- President and Chief Executive Officer

Yeah. We'll have the 10% customer detailed out in our K later this month.

Mauricio Munoz -- Raymond James -- Analyst

OK. Thank you. And then I wanted to go back to the Huawei question. Back in May, you guys reduced your June guidance by close to $33 million at the midpoint following the U.S.

addition of Huawei to the Entity List. Today's results highlight a close to $22 million beat to that guidance, again, at the midpoint, and I was wondering if you could give us some color on what portion of this beat could be attributed to your ability to ship more products into Huawei than you previously anticipated.

Chris Coldren -- Senior Vice President of Business Development

I think I'll start and let Alan finish. The $30 million something come down when we reguided. I think if you look what we ended up with was Huawei being down 25% or amounts to approximately $20 million. And so the net-net of that is obviously not as much as we were up, and therefore, I think as we highlighted in the prepared remarks, was really the industrial and consumer business that probably was the most significant driver of upside, though we were able to redirect some of that telecom business that we weren't able to serve Huawei to two other customers.

The challenge was just -- all of this happened very late in the quarter. So with our manufacturing lead times, it's difficult to redirect and get much impact within the quarter when it was really only about a month, a month and a half to go.

Alan Lowe -- President and Chief Executive Officer

I think that covers it, Chris.

Mauricio Munoz -- Raymond James -- Analyst

I know that you're not going -- not disclosing at this point what kind of products you're able to ship or currently able to ship into Huawei. What is -- given your prepared remarks, is it fair to assume that the majority of products outside of telecom [Audio gap].

Your next question comes from the line of Jun Zhang.

Jun Zhang -- Analyst

Thanks for taking my question. So do you mind if you give us a little bit color, how much capacity -- how much more capacity do you add to meet the current ROADM demand in order to the lower -- or shorter lead time for the ROADM supply? Thanks.

Alan Lowe -- President and Chief Executive Officer

Yeah. I think if you look at what we did in fiscal '19, we more than doubled the output of ROADM. We continue to add but don't expect to double again this fiscal year. So our capex plans for our fiscal '20 are lower than they were for fiscal '19, but off of substantially higher installed capacity base.

So the decisions that we made six months ago are coming online now, most of which are for the very high-end ROADM, MxN and high port count ROADMs. And we're going to continue to invest to bring that in. And I think as Chris mentioned, we are over $100 million in ROADMs. We grew last quarter.

We expect to grow this quarter. I fully expect to grow in the December quarter. And most of that growth will be coming from the very high end of ROADMs and ROADM blade. So I'm not going to give a number.

I think one of the other analysts said that they believe we had $130 million of installed capacity. I don't see any reason why we shouldn't be able to get to that level of ROADMs in calendar '20. So I hope that answers your question.

Jun Zhang -- Analyst

Sure. Thanks. And also, one more question. In addition to 5G and the ROADM, what else you're seeing the strength in the telecom market, which could provide the potential upside for your revenue in the next few quarters? Thanks.

Alan Lowe -- President and Chief Executive Officer

What other products we're seeing growth strength --

Jun Zhang -- Analyst

In the telecom space. Yeah [Inaudible] the upside. Yeah.

Alan Lowe -- President and Chief Executive Officer

Yeah. I'd say as we said in the prepared remarks, we saw a 10% growth in our coherent modules, so our ACOs and DCOs. So we're expecting continued growth. We're constrained on ACOs today, significantly constrained on ACOs as we've seen demand pick up more than anticipated.

And we are at the very early stage of DCO shipments that we expect that will continue to grow through the fiscal year and be a meaningful part of our telecom revenue over the next several quarters.

Jun Zhang -- Analyst

Thanks. That's all my question. Thanks.

Alan Lowe -- President and Chief Executive Officer

Sure.

Your next question comes from the line of Tim Savageaux of Northland Capital.

Tim Savageaux -- Northland Capital -- Analyst

Good morning, everyone, or should I refer to you as party A this morning? Throwing my two cents there. A couple of questions. With regard to the commentary around gross margins, I want to get a little more detail on that. You talked about being toward the upper end of a 40% to 45% target range.

Could you go over the timing on that again and whether that's driven by kind of organic improvements in telecom margins, better mix with less datacom, more 3D or what have you? And I have a follow-up.

Wajid Ali -- Chief Financial Officer

Yeah. Hi, it's Wajid. I'll start it off and then Alan and Chris can jump in as well. So obviously, product mix plays a role kind of quarter to quarter.

And so what we're talking about is looking five quarters out for a given product mix. What do we think our gross margins are going to look like? So there's a couple of positive trends that are happening organically that are supporting our margin target of 40% to 45%. Alan talked about the growth in datacom chip sales. We talked earlier about having more content with 3D sensing.

And in addition to all that, we're expecting to have $40 million worth of annualized synergies, which we mentioned earlier on the call, we've got clearly defined actions with time lines on. And so that's going to happen probably at the tail end of the five-quarter target that we've given, but it's really those three things that are driving our expectations on gross margins up looking forward. Even in the lasers business, as Alan mentioned earlier, we're expecting to see higher levels of revenue, and so that should help us from an organic gross-margin perspective as well. So it's all of those things combined.

Alan?

Alan Lowe -- President and Chief Executive Officer

Yeah. I would just add to that that I mentioned that we have $31 million of products, datacom transceivers and low-margin telecom products, but over the next several quarters are going to go to zero. That will help the average gross margin go up. But $10 million a quarter in synergy attainment mostly in COGS is going to be 2% to 2.5% in itself given no mix change.

So I think we're pretty confident in our ability to make that happen. So I think it's a combination of all of the above.

Tim Savageaux -- Northland Capital -- Analyst

Great. And to follow up on 3D sensing, it actually kind of levers out that datacom comment really depending on how fast you assume that drops off in your September quarter guide. What I see is actually pretty solid double-digit growth being implied on a year-on-year basis in 3D sensing and very strong sequential growth, obviously. And so to get to your kind of up slightly calendar guide, you need to have a pretty substantial decline in calendar Q4, and maybe that comes as a result of an earlier build cycle and maybe borrowing some of that here in the June quarter.

But from an overall trajectory standpoint, am I thinking about that kind of the right way?

Chris Coldren -- Senior Vice President of Business Development

I think, Tim, the absolute low, I think when we start talking about December, it's still a little further out. We've got plenty of time to manufacture [Inaudible].

Tim Savageaux -- Northland Capital -- Analyst

Well, you did guide to it. So --

Chris Coldren -- Senior Vice President of Business Development

Well, I think our point being is it depends on the timing of what we do this quarter, and as we highlighted also, what happens in the overall smartphone market. But I think based on the comments that we put in the script, that you're heading in the right direction.

Tim Savageaux -- Northland Capital -- Analyst

Great. Thanks.

Your next question comes from the line of Richard Shannon of Craig-Hallum.

Richard Shannon -- Craig-Hallum Capital Group -- Analyst

Hi, guys. Thanks for taking my questions. I guess a 3D sensing question for me. Alan, maybe if you can talk about the competitive environment here in terms of what you're seeing for capacity and also capability of competitors coming online here and also the degree to which there are opportunities out there in 3D sensing that may ask or maybe looking for lower specs but Lumentum may not be interested in competing for.

Alan Lowe -- President and Chief Executive Officer

Oh, we're interested in everything, Richard. I'd say that we've had two years of extremely high market share. And a year ago, we thought that that was going to go down, and it didn't. I think right now, we think it's going to go down, but we'll see.

I think our competitors are going to figure it out eventually. But as I said in the prepared remarks, by end of this fiscal quarter, we will have shipped over a half a billion units of 3D sensing products, and that's hard to -- hard for our competitors to keep up with. And the quality level and reliability level of the product we ship is phenomenal, absolutely phenomenal. So I think the combination of having scale, reliability and the investment in R&D for new products is going to continue to have us be out in front and that's why we're pretty confident.

Especially as you look forward into calendar '20, content per phone is going to go up, products are going to change to higher technology. I think we're going to continue to stay out in the front, and we're continuing to invest in new technologies to give our customers new capability to do these things with their devices.

Richard Shannon -- Craig-Hallum Capital Group -- Analyst

OK. That's helpful commentary. Second question for me on telecom stuff here. Obviously, ROADMs seems to be very strong trends here.

Maybe if you look out in telecom outside of ROADMs, what you're seeing here in terms of growth here from your non-Huawei customer base here. And do you worry about any sort of inventory build there?

Alan Lowe -- President and Chief Executive Officer

Inventory build outside of Huawei?

Richard Shannon -- Craig-Hallum Capital Group -- Analyst

Yes, and outside of ROADMs, yes.

Alan Lowe -- President and Chief Executive Officer

Outside of ROADM. No, I don't. I think we are -- well, set aside submarine, because I think that there was probably some shipments accepted last quarter in anticipation of this manufacturing and why we think that submarine will be down this quarter. I don't see a buildup of inventory, and in fact, I see the opposite, because we're still not able to, as I said, meet the demand for ACOs and coherent components, and ROADMs, clearly, are a challenge there as well.

Richard Shannon -- Craig-Hallum Capital Group -- Analyst

OK. Great. Thanks for that.
