摘　　要：根据耦合非线性薛定谔方程,通过计算机系统仿真,对相敏光放大器PSA作为在线放大器时不同系统传输速率和不同偏振模色散情况下系统传输性能进行了分析,并与掺铒光纤放大器EDFA进行比较。仿真分析得出,采用PSA作为在线放大器的系统性能优于EDFA系统性能,对光纤偏振模色散有一定的补偿作用。According to the coupling nonlinear schrodinger equation, by computer simulation, the paper analyzes fiber communication system transmission performance of phase sensitive amplifier （PSA） when used as on-line amplifiers at different system transmission rate and different polarization mode dispersion （PMD） situation, and makes comparison between PSA and erbium doped fiber amplifier （EDFA）. The simulation results show that the system performance of PSA used as on-line amplifier is better than that of EDFA and PSA which can compensate PMD in a certain degree.
