From time immemorial communication is an essential need for human beings. Communication happens through the channel. Among many channels for communication, Fiber is a vital wired channel that has infinite bandwidth and high noise immunity against electromagnetic interference. The phenomenon of dispersion is the major problem for high bit rate and long-haul optical communication systems. An easy solution to this problem is optical Solitons - Pulses that preserve their shape over long distances. Soliton based optical communication systems establish over distances of several thousands of kilometers with considerable information carrying capacity by using optical amplifiers.
