CWDM filter bandpass is wide to allow for drifting optics. Anything
within about 7nm of 1530/1550 should work fine. I've got some optics
near 34 and 59 on order to do exactly that in a bidir single fiber
arrangement. I'll report back my results.

I've wondered if one could shoot with DWDM

Zed,
If you are looking for optical systems my fav pub is Lightwave at
http://lw.pennnet.com/. They list DWDM and CWDM systems, lasers, optics, ROADM
etc. If you have nanog archives go back at least six months to the thread on
DWDM vs CWDM et al that I was one of the contributors to.

These are XFP-based. Thus, not a solution to the problem above.
Answer: Nobody's making 10GE CWDM-wavelength lasers. Why? I don't have
enough knowledge of optical
