Abstract :In this study, 20 Gb/s Dual Polarization Coherent Optical Orthogonal Frequency Division Multiplexing insert ignore into journalissuearticles values(DP-CO-OFDM); system is studied to obtain the relation between the Bit Error Rate insert ignore into journalissuearticles values(BER); and launch power for different transmission length and polarization mode dispersion insert ignore into journalissuearticles values(PMD); coefficient. DP-CO-OFDM system is simulated by designing a Monte Carlo simulation. In this simulation, the effects of chromatic dispersion, launch power and PMD coefficient on received signals are demonstrated with constellation diagrams and results are given in form of BER-Launch Power variations.
