About this document
Wavelength Division Multiplexing Overview by Jorge Rzezak is a document available to read on EtoBox.
Wavelength-division multiplexing (WDM) is a technology that multiplexes multiple optical carrier signals onto a single optical fiber by using different wavelengths of laser light. This allows for bidirectional communications over one fiber and increases network capacity. WDM systems use a multiplexer to join the signals and a demultiplexer to separate them. Dense WDM systems use close channel spacing to take advantage of erbium-doped fiber amplifiers, while coarse WDM systems have greater spacing to allow l
