摘　　要：为了进一步研究高速光孤子脉冲传输系统的特性，采用分步傅里叶方法对非线性薛定谔方程进行求解。数学分析及计算机仿真表明，脉冲的传输特性随偏振膜色散参量值的增加而恶化。最后分析了孤子间的相互作用，并提出了改善光孤子传输系统性能的解决方法。In order to analyze the property of optical soliton communication system, split-step Fourier method was used to calculate the nonlinear Schrodinger equations. The simulation results showed that the transmission characteristics of pulse became deteriorated as the parameters of polarization mode dispersion increased. At last, the interaction between solitions was analyzed and the measure for improving the optical soliton communication system was proposed.
