Since the inception of optical fiber communication in 1974, their transmission capacity has experienced a tremendous increase in the years after. Several technology advances spurred its growth. But its use was kept to long haul applications like intercity links and international links, because of its initial capital cost. Multiplexing is the transmission of information from one or more source to one or more destination over the same transmission medium. There are several domains in which multiplexing can be accomplished, including space, phase, time, frequency and wavelength. However, the three most main methods of multiplexing signals are time-division multiplexing (TDM), frequency-division multiplexing (FDM), and the more recently developed wavelength-division multiplexing (WDM). Wavelength Division Multiplexing is the technique that allows several different signals to be carried along a single fiber at the same time. It achieves this by using different wavelengths for each transmission and can be employed on single mode or multimode fibers.
