In the optical fiber communication systems, when the power is high, the impact of nonlinear effects become significantly important for transmission. In the Nonlinear effects, the Refractive index (RI) provides the significant information in multi-channel optical systems. There are various techniques have been proposed for multi-channel optical system using fiber nonlinearities. However, the proposed system offers the development and design of Wavelength Division Multiplexing (WDM) system designing using fiber nonlinearities effects for extraordinary data rate, extended transmission distance and low BER. These fiber nonlinearities are classified as Cross Phase Modulation (C/XPM) and Four Wave Mixing (FWM). In the designed system, the low BER using both these fiber nonlinearities effect compared to existing work. The paper demonstrates the generation of multiple signals due to nonlinearities effects between two or more wavelengths interact each other It is defined that using the FWM for WDM system, the BER of 1.13e-33 is achieved and XPM for WDM system produces BER of 1.5e-12. It is also demonstrated that WDM via FWM offers less BER compare to WDM system via XPM.
