Study and Investigation of FBG as a Dispersion Compensator for Different Grating Lengths and Apodization Functions

In order to upgrade the overall system performance of optical communication system affected by dispersion, several dispersion compensation techniques are proposed and analyzed. Fiber Bragg Grating (FBG) is most advanced technique for dispersion compensation in optical fiber communication system. In this paper, FBG has been studied and investigated as a dispersion compensator in optical communication system for different grating length and apodization functions at 10Gbps and 220km transmission fiber. All the simulation work has been done in "OptiSystem 7.0" simulation software. The simulated transmission system has been investigated on the different parameters that are Q-factor, BER, Eye height.
