I have a need for a few simple ITU-grid CWDM mux/demuxes. I'll be using
colored SFPs/GBICs for the active components. My link budget is about
11.5 db after link loss, not including muxes.

8-wave de/muxes seem to cost <$1k per strand per end, with connectorized
fibers(*). However, the cheapest 8-wave rack-mount mux I can find is
$2500(**), and 8-channel de/muxes seem to cost $3500-$5000 per end (two
strands).

Are 8-channel CWDM de/mux chassies anything more than just a pair of
8-wave mux modules, mounted into a fiber termination panel?
