Investigation Of Fwm Effect On Ber In Wdm Optical Communication System With Binary And Duobinary Modulation Format

摘要

This paper simulates two channel WDM optical communication system to investigate the effect of FWM on Bit Error Rate for Duo-binary & binary modulation like NRZ Rectangular at different dispersion value ,core effective area of fiber & channel spacing for 100km long optical communication system. BER got improved with duobinary modulation format & by increasing core effective area which will offer a significant performance benefit in digital systems.
