The given paper presents the chromatic dispersion compensation scheme in WDM PON system for long haul communication consisting of the single mode fiber with the help of the FBG (fiber Bragg Grating). During the entire optimization process the major concern are provided to the vital parameter of the FBG in which the Duty cycle, the Input power, the Modulation coding, the band width of the of the FBG are deeply considered. By improving the parameter to the extent and incorporating them into the optimization process the output response improved tremendously. The output response is well elaborated with the help of the minimum BER, Q factor and the various plotting process which practically insists the improvement in the output.
