Wavelength Division Multiplexing (WDM) is to combine two or more optical carrier signals of different wavelengths (carrying various kinds of information) at the transmitting end through a multiplexer. A technique of transmitting into the same fiber of an optical line; at the receiving end, a demultiplexer separates optical carriers of various wavelengths and then is separated by light. The receiver performs further processing to recover the original signal. This technique of transmitting two or more different wavelength optical signals simultaneously in the same fiber.
