Minimization of Four Wave Mixing Effect in Long-Haul DWDM Optical Fiber Communication System

Abstract

Four Wave Mixing (FWM) of nonlinear effect is a major damage and degradation of the signal quality in the DWDM system. In this research paper, the proposed DWDM system is 70 km fiber length at 10 Gbps bit rate with 3 channels and channel spacing is 100 GHz. By using increasing dispersion coefficient techniques and dispersion compensated fiber mitigate the impact of FWM. The performance of the system evaluated on Bit Error Rate (BER) and Quality factor (Q-factor) which are simulated on commercial Optisystem (version-16) software. The results showed the decreasing of BER value, which got the superior performances and enhanced signal quality with more bandwidth in long-haul optical fiber communication.
