摘　　要：采用一阶摄动理论分析了准线性光传输系统的非线性相位噪声,在此基础上得出中置光学相位共轭器的准线性光传输系统的非线性相位噪声的方差的理论表达式,并围绕理论推导得出的非线性相位噪声的性能参数进行数值计算。计算结果表明在光放大器和传输系统的终点到光学相位共轭器等距的情况下,采用光学相位共轭器的色散补偿光传输系统可以完全消除非线性相位噪声对非线性系数的一阶影响。The paper focuses on the analysis of nonlinear phase noise in optical transmission system. The ana- lytical expression for the variance of nonlinear phase noise is obtained. And the numerical calculation of the nonlinear phase noise is deduced. The calculation results show that the nonlinear phase noise added by the op- tical amplifiers can be compensated by the OPC located after the optical amplifiers.
