Performance comparison of phase modulated formats in 160 Gb/s transmission system

The performance of DPSK and DQPSK with NRZ, 33% RZ and CSRZ formats are numerically compared and investigated for 160 Gbit/s single channel transmission system. The impairments caused by chromatic dispersion (CD), higher-order chromatic dispersion, nonlinearity and accumulated noise are considered. The primary limitation for those modulation formats in 160 Gbit/s transmission system is investigated.
