✦ Synopsis

A detailed theoretical analysis is presented to evaluate the combined in uence of self-phase modulation (SPM) and group velocity dispersion (GVD) of optical ÿber on the bit error rate (BER) performance of a heterodyne optical CPFSK system. The power penalty su ered by the system due to the combined in uence of GVD and SPM is evaluated from the BER performance results. It is found that the penalty due to SPM at a BER of 10 -9 is signiÿcant when the input power exceeds 7 dBm. Further, the CPFSK system with modulation index of 0.5 is less sensitive to the e ects of GVD and SPM compared to the system with a modulation index of 1. The theoretical results are in conformity with the experimental results reported earlier.
