The growing demand for increased data rate transmission throughout communication networks has recently created tremendous interest in the field of fiber optic telecommunication. With the deployment of fiber optic cables and the use of dense wave division multiplexing (DWDM), optical data transmission has allowed much greater transmission rates in comparison to its electrical counterpart. Fiber optic cables, each carrying multiple wavelengths of light, are replacing metallic cables. Each wavelength of light denotes a data channel in similar fashion to the multiplexed frequencies that denote television channels traveling through an electrical coaxial cable. Transmission of each optical signal begins with a wavelength-tuned light source at the entrance of the fiber optic cable. Each data channel or wavelength requires a light source emitting at the appropriate wavelength. The optical signals then travel throughout the network and are eventually delivered to the proper destination.
