Due to the vagaries of telecom pricing, I've ended up with a 2.5gig wavelength service between two locations when what I really wanted was a gig-e or two.
I'm really not sure if this is a "transparent" wave service or not... the carrier is using gear from Ciena to hand it off to us and they seem to be big on transparent waves, so maybe it is, but nobody seems to be able to say for sure.
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
