Chromatic dispersion is a critical factor that limits the quality of transmitted optical signal in high speed fiber optic communication systems. Chromatic dispersion occurs due to the propagation delay spread of different spectral components of the transmitted signal. This leads to the pulse broadening of transmitted signal. In order to operate the fiber optic communication system with a sufficiently low bit error rate and to minimize the performance degradation caused by pulse distortion and broadening, dispersion compensation is needed. The purpose of this project is to compensate the chromatic dispersion using fiber Bragg grating and optical phase conjugation techniques. Simulation results will be obtained using OPTSIM software version 5.3. Effect of chromatic dispersion in an optical fiber link was analyzed. Simulation using Fiber Bragg grating by varying its grating period and linear chirp coefficient was obtained.
