    Coarse Wavelength Division Multiplexing

    What Does Coarse Wavelength Division Multiplexing Mean? Coarse wavelength division multiplexing (CWDM), a variant of wavelength division multiplexing (WDM), is an optical transmission technique used for shorter distances as compared to dense WDM (DWDM). CWDM transmits few channels and makes use of wider spacing in between the channels for distances...
