Abstract :
In order to study the effect of nonlinear phase noise on the performance of DQPSK modulation system, based on the analysis of mathematical model of nonlinear phase noise, the property of bit-error rate(BER) varying with optical signal-to-noise ratio(OSNR) at transmitter is simulated in 40Gb/s DPSK and DQPSK system. The result shows: compared with DPSK system, DQPSK system is more sensitive to the effect of nonlinear phase noise, and the BER will obviously increase when the nonlinearity is big enough, by which communication quality of the system will be surely seriously influenced.
