Abstract :
Waveform degradation due to polarization and chromatic dispersion in a single-mode fiber is calculated for a coherent continuous-phase frequency-shift-keying (CPFSK) signal. Both kinds of dispersion distort the amplitude of the baseband signal and can limit transmission distance and capacity. For instance, polarization dispersion of 5 ps will restrict a bit rate by ~60 Gb/s when chromatic dispersion is fully reduced using a dispersion-shifted fiber or applying electrical equalization
