a 100 Gbit/s optical Polarization-Multiplexed(POLMUX)-Carried-Suppressed Return-to-Zero(CSRZ)-Differential Phase-Shift Keying(DQPSK) transmission system is established and a Frequency Domain Phase Conjugation(FDPC)-based 100 Gbit/s optical transmission system studied.The analysis shows that FDPC can compensate both the system dispersion and nonlinear effects
having greater advantages than the conventional Dispersion Compensating Fiber(DCF)-based technologies.
