Traditional CWDM Mux/DeMux vs. FMU Series CWDM Mux/DeMux

With the need for bandwidth increasing, 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 […]

Talk about WDM Devices and Fiber Optical Splitters

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 […]
