Abstract
The effect of various subcarriers is investigated on coherent optical orthogonal frequency division multiplexing (CO-OFDM) using Dual Polarization Quadrature Phase Shifting Keying (DP-QPSK) modulation technique. In proposed system, we have used coherent detection to improve the system performance. The performance of proposed system is investigated in terms of bit error rate (BER), received optical power and constellation diagrams of the received signals. The results show that the network performance is improved by decreasing the overall dispersion of the fiber link using coherent detection..
