摘　　要：本文利用矩方程的方法，对光纤非线性色散的脉冲展宽进行分析研究，给出了均方根脉冲宽度随距离变化的级数表达式，以便在实际应用中根据具体要求，给出不同精度的脉冲展宽值。同时合理均衡线性、非线性和入射波三者的系数，实现脉冲展宽的相互补偿，减缓脉冲展宽度。The propagating pulse broadening case in a non-linear dispersive optical fiber is studied by means of moment equation and the series formula. The relationship between rms pulse width and the transmission distance is deduced and used in pratically analyses. The pulse width with different precisions can be obtained from our series formula according to the pratical demand,from which the constant of pulse width is reduced by compensating the constants between linear, nonlinear and induced wave.
