The goal of an optical fiber communication system is to transmit the maximum number of bits per second over the maximum possible distance with the fewest errors. Single mode optical fibers have already been one of the major transmission media for long distance telecommunication, with very low-losses and wide-bandwidth. The most important properties that affect system performance are fiber attenuation and dispersion. Attenuation limits the maximum distance. While dispersion of the optical pulse as it travels along the fiber limits the information capacity of the fiber. But using of optical amplifiers allows one to eliminate the limiting of the length of section between the transmitter and the receiver.
