With the need for bandwidth increases, the WDM (wavelength division multiplexing) technology was developed to expand network capacity over a single fiber. It uses a multiplexer (Mux) at the transmitter to combine several signals together, and a demultiplexer (DeMux) at the receiver to split them apart. Most WDM systems operate on 9µm single-mode fiber optical […]

WDM Multiplexers and Demultiplexers Wavelength Division Multiplexers, just we usually called it WDM, it includes CWDM and DWDM. Practically all DWDM systems use array waveguide (AWG) multiplexer/demultiplexers. The Figure shows a schematic layout of an AWG demultiplexer; a multiplexer is identical but for the fact that several signals enter from the waveguides that are the […]
