Optical fiber systems play a pivotal role as the foundational infrastructure for global broadband networks. The augmentation of bandwidth capacity is achieved through the implementation of DWDM optical networks. However, the efficacy of DWDM Optical Communication Systems is impeded by nonlinear effects, with Four Wave Mixing (FWM) standing out as a notable contributor to system performance degradation. Here a DWDM system is suggested in which certain procedures are incurred so that Four Wave Mixing can be reduced and with the help of BER analyzer the efficiency of FWM is observed in terms of Quality factor and Bit error ratio.
