Now what

The update shouldn't come as a complete surprise. Last Wednesday, Rosenblatt analyst Jun Zhang initiated coverage on Oclaro with a buy rating and $12-per-share price target -- a hefty premium to Oclaro's current price of $9.37 per share.

"We believe that China Mobile's Phase 12 60T procurement and China Telecom's Metro upgrade are likely to begin in June and September/October, respectively, which should help reignite industry demand and push OCLR back to its normal revenue levels by the end of this year," Zhang explained at the time. "We believeChina's optical demand can resume its growth in 2018 with more metro-level upgrades."

In the end, if that prediction proves accurate, I suspect the recent gains enjoyed by investors in each of the above-mentioned optical communications companies could be just the beginning.
