Wavelength-Division Multiplexing (WDM)

WDM is an abbreviation for Wavelength-Division Multiplexing, and is now one of the most widely used technology for high-capacity optical communication systems. At the transmitter side, multiple optical transmitters – each emitting at a different wavelength – individually send signals and these signals are multiplexed by a wavelength multiplexer (MUX). The multiplexed signals are then transmitted over one main transmission line (optical fiber cable). At the receiver side, the signals are de-multiplexed by a wavelength de-multiplexer (DEMUX) and sent to multiple receivers.
