提出并验证了一种基于 NLS(非线性薛定谔)方程的光通信设备参数理论估算分析方法。该方法以脉宽大于5 ps 的光脉冲为例作方程推导分析，分别得到非线性功率与色散脉宽两个创新参量。在 WDM(波分复用)+TDM(时分复用)-PON(无源光网络)系统中进行带参模拟仿真，支持上行/下行为160/170 Gbit/s的总带宽，最终得到最佳输出功率值，其对应理论误码率可达到10-50。仿真结果验证了理论估算分析方法的可行性，对设备参数设置有较大的参考价值。

A Nonlinear Schrodinger (NLS)equation-based theoretical analysis method for the parameter estimation of optical communication devices is proposed and validated.In this method,a light pulse with width of over 5 ps as an example is derived and analyzed and two innovative parameters of nonlinear power and dispersion width obtained.They are simulated with refer-ence in WDM+TDM-PON systems,supporting the total bandwidths with uplink/downlink as 160/170 Gbit/s and obtaining the optimum output power value corresponding to the theoretical BER of 10-50 .Simulation results verify the feasibility of this analysis method,which provides a valuable reference for device parameter settings.
