In simple terms, a passive CWDM implementation involves placing VAM modules and upgraded transmitters and receivers at each end of the network segment. CWDM equipment performs two functions: 1) segregates the light to ensure only the desired combination of wavelengths are used, and 2) multiplexes and demultiplexes the signal across a single fiber link.
