| 摘 要： | 利用分离信道的分步傅立叶法对信道间距为0.8nm的8路10 Gbit/s波分复用色散补偿系统进行仿真实验，分析了在具有级联光放大器系统中光纤色散和各种非线性效应（自相位调制SPM、交叉相位调制XPM、四波混频FWM）对系统传输的影响。仿真结果表明，在色散补偿WDM通信系统中，SPW对系统传输造成的损伤最大。并且由于非线性效应、传输损耗及噪声的综合影响，应当选取合适的系统输入功率。

| Abstract: | During the nonlinearity simulation based on divided channel split step Fourier method in 10 Gb/s 8 channel WDM system with channel space of 0 8 nm, the impairment in WDM system with Erbium-Doped Fiber Amplifier raised by chromatic dispersion and nonlinear effects(SPM, XPM and FWM) are presented here. The results indicate that in dispersion compensated WDM communication system the impairment raised by SPM can't be ignored. And due to the integrated infection of nonlinear effects?transmission lose and noise, an appropriate input power exists in definite system. |
