As the signal propagates through a fiber optical communication system it suffers from attenuation and dispersion. Attenuation determines the repeater less separation between a transmitter and a receiver, while dispersion causes the signal pulses to broaden as they travel along the fiber. In other words attenuation is the process of weakening of a signal as it propagates through a fiber and dispersion limits the information carrying capacity. Either repeaters or optical amplifiers may compensate these losses. Due to pulse broadening two neighboring pulses interfere with each other and…mehr

As the signal propagates through a fiber optical communication system it suffers from attenuation and dispersion. Attenuation determines the repeater less separation between a transmitter and a receiver, while dispersion causes the signal pulses to broaden as they travel along the fiber. In other words attenuation is the process of weakening of a signal as it propagates through a fiber and dispersion limits the information carrying capacity. Either repeaters or optical amplifiers may compensate these losses. Due to pulse broadening two neighboring pulses interfere with each other and information in the pulses gets overlapped. This can be attributed to many factors. One of the basic reasons is the non-linear property of the fiber. These effects are not effective at low power intensity, but degrade the signal at high power levels. Before 1960 LED's were main source of optical communication, which operate at a low power level. With the advent of highly coherent laser beams the electric field strength can be 3 1010 V/m, which is of the order of atomic fields. At such high field the relation between polarization and field's strength becomes nonlinear. In fact at high power level refract
