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...

Wavelength Division Multiplexing
What Does Wavelength Division Multiplexing Mean?Wavelength division multiplexing (WDM) is a technology or technique modulating numerous data streams, i.e. optical carrier signals of varying wavelengths (colors) of laser light, onto a single optical fiber. WDM enables bi-directional communication as well as multiplication of signal capacity. WDM is actually frequency division...

Dense Wavelength Division Multiplexing
What Does Dense Wavelength Division Multiplexing Mean?Dense wavelength division multiplexing (DWDM) is wavelength division multiplexing (WDM) with typical channel spacing of 100 GHz for 40 channels and 50 GHz for 80 channels. Each channel contains a TDM (time division multiplex) signal. And each of up to 80 channels can carry...
