摘　　要：在同时考虑自相位调制、交叉相位调制和四波混频非线性效应的情况下,研究了预补偿、后补偿和混合补偿三种色散补偿系统输入功率与误码率的关系.比较了不同的色散管理系统下,由带内交叉相位调制和带内四波混频引起的定时抖动与寄生脉冲对系统的影响.由于非线性效应、传输损耗及噪声的综合影响,应当选取合适的入纤功率以使得系统获得最佳的传输性能,本文找到了其中最优系统的最佳入纤功率.The relationships between impulse power and error bit of the traditional dispersion-compensated systems： pre-, post-and hybrid-compensation in the presence of SPM, IXPM and IFWM were investigated. The effects of the IXPM and IFWM on the three different dispersion-managed systems were studied and compared with numeratial simulation. The optimal value of the input power, which should be carefully chosen due to the interaction among nonlinearity, fiber loss and the noise, was found to optimize the performance of the optic fiber transmission system.
