Ciena (CIEN -2.6%) falls after Raymond James' Simon Leopold throws cold water on the Street's excitement over the company's growing 100G optical transmission gear sales. 100G still only makes up 6% of Ciena's sales, Leopold notes, and while that number will grow next year thanks to design wins, it will bring with it a margin hit. Ciena fell last month after warning of "slower-than-expected rollouts" for new design wins.
