Focus on development of broadband optical communication systems is incredible since it offers combination of wide bandwidth and low losses unmatched by any other transmission medium, but group velocity dispersion and fiber non linearities remain inherent limitations of such systems there by degrading the performance. Fiber non linearity have become one of most significant limiting factors of system performance since the advent of Erbium-Doped Fiber Amplifiers (EDFA s) because input power is increasing and the effects of fiber non linearities are accumulating with the use of EDFAs.
