We use these types of circuits and I manage several others for clients. Every time I turn one up I make sure I talk to an engineer and ask if they are expecting a 2.5Gig signal and just going to use transponders to put my 1310nm signal into a DWDM color send it to the other side, and transponder it back to 1310nm. They've always said that's exactly what they are doing. I used Cerent 15454 (now Cisco) w/ Oc48 IR 1310 cards facing the wave, and proper cross connect and Gig cards (carefull here) facing my gig switches. Shoot me an off list message and I'll help you w/ the ins and outs and share the costs we budget for such. I haven't used MRV but they look appealing, would love to hear other folks experience with them as I'm about to have to turn another two of these up... -- W. Kevin Hunt CCIE #11841
