This occurred to me the other day.If I had four different colors of CWDM SFP modules, obviously I could use a CWDM Mux to connect all of them to the same fiber. Would a 1x4 PLC splitter also work? All 4 SFP's would receive all 4 wavelengths, but wouldn't they only respond to the one wavelength they're coded for? You could do something like that with radios if you had sufficient frequency separation.
Just curious.
