  No, because the CWDM SFP RX side is not wavelength selective. That's why you 
use the demux to separate the wavelengths.

[AFMUG] WDM Stupid Question

2017-11-01 Thread Adam Moffett 

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.
