Your last post actually answered my question. I'm selling tomorrow.

Are there fiber networks out there that use OC-48 or OC-192, and need 16 times or higher multiples of bandwidth in the near term? If these are mostly new network buildouts, the likes of Qwest Communications, they may not need the extra bandwidth for a while.

<< If there is one complaint I have about CIEN it's that I don't hear anything about their WDM being compatible with OC-192.>> There is no reason why CIEN can't offer OC-192. However, their gameplan is to offer OC-48 with closer channels. This is more compatible with existing networks and amplifiers. If they wanted to offer OC-192 they would probably need to keep channels 50 GHz spaced limiting them to 40 channels or so. It would depend on how the carrier wants to manage the network. Also, consider that carriers already have terminal equipment to switch at STM-16 (OC-48 counterpart) rates. So OC-48 is a better match to existing equipment. I do not believe that there are any OC-192 terminals in operation yet. Most OC-192 systems mux 4 STM-16 channels anyway, i.e. there are no 10 Gb/s data streams coming in from the electrical side. So it all depends on how you want to slice the pie.
