The optical fiber is the enabling and promising technology used in almost all the trunk lines of existing networks.In optical fiber communication, the attenuation is the major limiting factor imposed by optical components or by fiber itself which degrades the system performance and limits the reach of the signals.To compensate attenuation factor the optical amplifiers boosts the signals without going through the costly conversions from optical to electrical signal and vice versa. But due to the various non-linear effects and phase noise present in the optical amplifier, its use is restricted...
