What happened

Shares of Oclaro (NASDAQ:OCLR) fell 18.4% in April 2017, according to data from S&P Global Market Intelligence.

So what

Chinese networking giant Huawei sat at the hub of Oclaro's April woes. First, analyst firms MKM Partners and Raymond James kept their bullish ratings on Oclaro but lowered their price targets due to signs of lower orders from Huawei.

Then, The New York Times caught wind of U.S. regulators digging into allegations that Huawei may have broken American trade sanctions in dealings with Iran, Syria, Sudan, and Cuba. Huawei is Oclaro's largest customer, and what's bad for the client also seems terrible for the component supplier. Oclaro shares plunged 11% lower on this report.

Now what

When Oclaro got around to reporting its third-quarter earnings in early May, the company delivered strong results but set revenue targets for the upcoming period on the low side. Oclaro CEO Greg Dougherty pinned the soft sales on -- you guessed it -- slower orders from China.

The trade sanction scandal could continue to weigh on Huawei and Oclaro until it is resolved, but the rest is short-term noise. Don't let one weak quarter distract you from the fact that high-speed networking is a positive long-term story. Speed bumps notwithstanding, Oclaro is looking at a fantastic runway for sales and earnings growth right now -- alongside many of its sector peers.
