摘　　要：文章采用计算机系统仿真的方法,通过数值求解简化的基本传输方程和非线性薛定谔方程,研究了采用相敏光纤参量放大器(PSA)作为在线放大器时,偏振模色散(PMD)对系统传输性能的影响。系统传输方案采用平均孤子系统。仿真结果表明:当PMD系数增大时,孤子脉冲出现分裂和展宽,幅度出现衰减,从而导致系统的传输性能下降。In this paper,we theoretically analyze in computer simulation the effects of Polarization Mode Dispersion（PMD） on the transmission performances of soliton systems when a Phase Sensitive Amplifier（PSA） is used as an in-line amplifier.In the simulation,we numerically solved the simplified basic transmission equation and the generalized nonlinear Schrodinger equation（NLSE） and use an average-soliton system as the transmission system.The simulation results show that as the PMD coefficient increases,soliton pulse is split and broadened and its amplitude decreases,resulting in the drop of the system transmission performance.
