Abstract:  Fiber  Bragg  Grating (FBG) is one of the applicable and important components in optical communication system. In this  paper, chirped  FBG has been studied as a dispersion compensator in an optical communication system for the different lengths of grating and apodization functions. All the simulations are done in OPTISYSTEM 7.0 simulation software at 10 Gbits/sec and 210 km of transmission fiber. The simulated transmission system has been analyzed on the basic of different parameters, which are BER, Q-factor, Output power and Eye height.


Keywords: Fiber Bragg Grating (FBG), eye diagram, BER and Q-factor.
