基于optisystem详细讨论如何构建一个完整的WDM仿真系统,分别给出4波长和8波长WDM系统在传输距离为340km和500km的合波器与分波器输出信号及其仿真眼图,并进行比较分析。结果表明此仿真系统能够很好的模拟WDM长距离传输系统,为进一步对WDM传输系统进行平滑升级扩容提供参考。
This discussed how to design a simulation model of WDM based on Optisystem in this thesis,given and compared the eye diagrams of 4 wavelengths and 8 wavelengths of WDM system in 340 kilometers and 500 kilometers.The simulation results showed that the proposed model to the long distance transmission system of WDM is good,and this model also provided reference to expanding the capacity of WDM communication system in the future.
