| 摘 要： | 研究了光纤色散对波分复用(WDM)系统中受激喇曼散射(SRS)非线性效应的影响.提出了一种简便且物理意义明确的分析计算模型,它适合于任意输入信号、任意信道数,以及不同的色散参量.基于该模型,深入分析了两信道光纤通信系统中,各种色散参量下,色散对SRS的影响,得出了色散能减小SRS效应所引起的输出功率的波动的结论,并且给出了在不同色散参量下,输出功率标准差随距离变化的曲线.

| Abstract: | In theory,the influences of the dispersion on nonlinear effect of stimulated Raman scattering(SRS) have been discussed in wavelength division multiplexing(WDM) systems.A simple and explicit model on stimulated Raman scattering has been proposed.It is fit for arbitrary input signal,channel number and dispersion parameter.By using this model,the influences of the dispersion on SRS in two channels and different dispersion fiber communication systems have been deeply analyzed.It is concluded that the dispersion can decrease the fluctuation of output power caused by SRS,and the output power standard deviation curve as distances under the condition of different fiber dispersion parameters are given. |
