I believe that CIEN has room to improve.  Particularly its gross margins.  This should be no problem with the upcoming cycle of network upgrades, it should lift all boats.  Telecom Service Providers will have to open their wallets sooner or later, the past year and a half was plagued by consolidation among providers and a tightening of CapEx budgets, this can last only so long.

I believe that CIEN and INFN are decent bets over the next 24 moths.
