Abstract: The nonlinear effect degrades the system performance. Because nonlinear effects tend to manifest themselves when optical power is very high, they become important in WDM. Four-wave mixing (FWM) is one of the dominating degradation effects in wavelength division-multiplexing (WDM) systems with dense channel spacing and low chromatic dispersion on the fiber. Four wave mixing (FWM) is a parametric process in which different frequencies interact and by frequency mixing generate new spectral components. FWM can have important deleterious effects in optical fiber communications, particularly in the context of wavelength division multiplexing where it can cause cross-talk between different wavelength channels, and /or an imbalance of channel powers. The paper presents the design and performance analysis of four-wave mixing effect on the basis of output spectrums, eye diagrams, BER, eye opening and Q-factor for different values of channel spacing.
