Abstract :
An analytical approach is developed to determine the impact of signal phase distortion due to polarization mode dispersion (PMD) on the bit error rate (BER) performance of optical heterodyne continuous phase FSK (CPFSK) system with delay demodulation receiver. The computed results at a bit rate of 10 Gb/s show that the CPFSK system suffer a significant amount of power penalty due to the effect of PMD. At a modulation index of 0.5, the penalty at a BER of 10-9 is found to be 1.0 dB, 1.8 dB and 2.8 dB when the differential group delay is 10 ps, 50 ps and 100 ps respectively for fiber length of 100 km. At modulation index of 1, the penalty is approximate 3.75 dB for differential group delay of 10 ps
