In this paper, different dispersion compensation techniques are used to compensate the positive dispersion. Three schemes Pre-compensation, Post-compensation, Symmetrical-compensation of DCF, Electronic equalizer of dispersion compensation with DCF and on FBG are proposed. The simulated transmission system has been analyzed on the basic of different parameters by using OptiSystem 7.0 simulator. The results of these dispersion compensation methods are compared in terms of different parameters, which are Q-factor, BER, Eye height and threshold value, investigated at the receiver end. Further, it has been observed that the system needs proper matching between EDFA gain and the length of the fiber for the optimum performance.
