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? -- Alex Rubenstein, AR97, K2AHR, alex@nac.net, latency, Al Reuben -- -- Net Access Corporation, 800-NET-ME-36, http://www.nac.net --
