It is very important to compensate the dispersion and non linearity present in the optical backhaul so that it is compatible with upcoming technologies. Optical Frequency Division Multiplexing (OFDM) is a physical layer, Multicarrier Modulation Technique (MCT) which is being widely used to design Back Bone (BB), Back Haul (BH) and Cognitive Optical Networks (CONs). Fiber nonlinearity present in dispersion managed links limits the capacity of an OFDM link, as it gets enhanced by high Peak to Average Power Ratio (PAPR) value of the transmitted signal. This work aims to decrease the PAPR value and hence in turn reduce the non linear impairments present in the coherent OFDM optical fiber link. In this work L2-by-3 non linear transform has been implemented to mitigate various fiber non linear effects through PAPR reduction.
