Abstract: This paper review of the chromatic dispersion compensation in optical fiber communication system. In optical communication system to compensate dispersion Fiber Bragg grating (FBG) is one amongst the applicable and necessary components. During this the appliance of chirped FBG was studied as a dispersion compensator in optical communication systems. This paper studied the various types of simulation in optical fiber communication system. The reviews of the analysis based on the chromatic dispersion are studied in the paper.

Keywords: (DCF) Dispersion Compensating Fiber, (OPC) Optical Phase Conjugator,(FBG)Fiber Bragg Grating.
