Optical Fiber Communication is the rapidly evolving form of communication for long haul applications. Due to its compact size, low losses and versatile application, it is significantly used in thousands of kilometers of distance. But the major limiting factor of using fiber technology is Dispersion. It causes pulse broadening due to multiple signals propagation in Wavelength Division Multiplexing (WDM) network and leads to inter-symbol interference. To overcome the effects of dispersion, many dispersion compensation technologies has been adopted. Dispersion Compensation Fiber (DCF) is one of the compensation scheme used in fiber optics. In this paper, a WDM channel having 8 * 20 Giga bits per second link capacity has been analyzed using pre compensation, post compensation and symmetric compensation with different encoding schemes(NRZ and RZ). The results are investigated in terms of Quality factor (Q-factor) and Bit Error Rate (BER). The simulation is carried out in OptiSystem 7 simulator.
