Ciena is holding all the cards. Tier 1 telco customers who are building out metro, tier one webscale customers building out DCI and clouds, and a lower valuation than INFN. I'd sooner buy more CIEN than INFN.
"Many accounts are starting to warm up to Ciena on the potential to see 100G metro upgrades, submarine deployments, and data center interconnect opportunities drive better results over the next few quarters, with valuation likely limiting downside from recent levels. We sense strength in Ciena is being funded in part by selling in Infinera, as many believe the former company is better positioned to capitalize on the large US metro builds that are likely to start playing out over the next few quarters."
"* CIEN: Strong results, positive guidance, reiterating Buy
* Ciena surpassed Street expectations for 2Q16 and provided strong guidance for 3Q16, prompting a double digit rally in CIEN shares
* Growth in the quarter was broad based and was particularly encouraging in non U.S. Americas and in Asia Pacific
* From an end user perspective, Ciena is reporting strong demand for its packet solutions and from webscale customers
* We regard Ciena as the premier company in the global optical communications space. Ciena continues to grow faster than peers, boosting its market share while improving its mix. We are reiterating our Buy rating to a 12 month target price of $30."
