CWDM Optical Mux

Hi. It's me again, on my eternally quest for information.

This time, it's about CWDM Muxes.

Assume that I have a Cisco CMUX system (dark out the back, handing off
CWDM waves in the front).

Who knows of a small, easy, cheap system that can take a CWDM wavelength
in, and mux a few oc12's onto it? Perhaps oc48-cwdm out the back?
