摘　　要：在线性密集波分复用 (DWDM)的具有非线性效应的喇曼增益光纤通信系统中 ,建立和求解任意信号通过具有自相位调制 (SPM)、交叉相位调制 (XPM)效应、群速色散 (GVD)、受激喇曼散射效应 (SRS)的信道时的传播特性方程 ,依据一定的系统条件 ,得到更加全面的理论结果。重点讨论了对光信号进行在线放大 ,构成分布式放大的基本规律和光纤非线性效应对线性波分复用光纤通信系统有一定的补偿作用。this artical on-line density wave division multiplexing(DWDM)take on non-linear effect'raman gain in the optical fiber communication system,foundation and solve arbitrary signal passing take on automatic phase modulation(SPM),cross phase modulation(XPM)effect,group velocity dispersion(GVD),stimulated raman scattering effect(SRS)'propagation characteristic equation,according as certain system condition,get much more comprehensive theoretical result,both keystone discussed that for optical signal proceed on-line magnify,constitute distributivity magnify basic and nonlinear effect of optical fiber for linear wavedivision multiplex optical fiber communication system has certain compensation,some conclusion with else literature report experimental analysis result and numerical solution came to the same thing.
