The results for the last of the optical networking majors are in, and it's good news.

Finisar (Nasdaq: FNSR) just released preliminary sales and earnings for the second quarter, and they're both stronger than expected. Sales will land at roughly $240 million, and earnings should come in at $0.42 per share, give or take a penny. The optical components maker thus underscores the message from industry peer JDS Uniphase (Nasdaq: JDSU) last week: Optical networking is still a strong industry, and rival Oclaro's(Nasdaq: OCLR) problems are unique to that company.

Finisar's good news is dragging Oclaro and Oplink Communications (Nasdaq: OPLK) along on the ride for some nice intraday gains, deserved or not.

Looking beyond the second quarter, Finisar expects the growth story to continue into the third. However, if the second quarter ends up at the bottom end of the preliminary report and the third at the top end of guidance, the sequential revenue gain between the two would land just below the 10% mark and snap an impressive streak of six quarter-by-quarter improvements above that benchmark.

That would still be an impressive result, of course. It's just kind of sad to see long streaks of success coming to an end, however arbitrarily defined. Yeah, I'm a big softie.

So what's next for Finisar after pushing its share price 137% above the year-ago mark? The stock is trading at a forward P/E in the teens, though that might be subject to change as analysts adjust their expectations. That isn't terribly expensive for a company of Finisar's growth habits. Assuming that the growth trend in optical networking has legs, which I do, it's not hard to imagine further growth from this important cog in the sector's machinery.

I'm heading over to CAPS to slap an "outperform" rating on Finisar for the next couple of years. You're welcome to follow along if you like, or drop down to the comments box to tell me why I shouldn't go there.
