Abstract: Various techniques are used for the dispersion compensation of the fiber and two of them are Dispersion Compensating Fiber (DCF) and Optical Phase Conjugation (OPC). In this paper the performance of the system is analyzed by comparing various results at the receiver. A 10Gb/s NRZ signal is launched onto a 100 km long Single Mode Fiber (SMF). Then fiber length is increased by increasing number of fiber spans. The length is varied up to 500 km. Results in the terms of eye diagram, BER, Q-factor are shown and it can be seen that results of a system which consist of OPC are enhanced because of proper dispersion compensation.
Keywords: Dispersion Compensating Fiber (DCF), Optical Phase Conjugation (OPC), Single Mode Fiber (SMF).
