Analysis of Nonlinearity in High Speed Differential Phase Shift Keying Optical Transmission System
The nonlinear effect in high speed differential phase shift keying (DPSK) optical transmission system is analyzed in this paper. The fine dispersion management can mitigates the system performance degrade induced by nonlinearity. The relationship between Q-factor and dispersion precompensation distance are discussed detailed, and an optimized dispersion precompensation distance where has a maximum Q value is reached through simulating the 40Gbit/s DPSK dispersion pre-compensation transmission system.
