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...
