Title: Waveform degradation due to dispersion effects in an optical CPFSK system
Abstract: Waveform degradation due to polarization and chromatic dispersions in a single-mode fiber is calculated for a coherent CPFSK signal. For a single-mode fiber with polarization dispersion of <or=1 ps, chromatic dispersion almost dominates the system. However, if a fiber has polarization dispersion of more than a few picoseconds and a chromatic dispersion of less than 0.1 ps/km/nm, which can be attained by using a dispersion-shifted fiber and/or by electric dispersion compensation, polarization dispersion will restrict transmission capacity. For instance, polarization dispersion of 5 ps will restrict a bit rate by approximately 60 Gb/s when chromatic dispersion is fully reduced using a dispersion-shifted fiber or applying electrical equalization.<<ETX>>
