四通路OADM系统的运行仿真

Simulating 4 Accesses fiber-grating OADM system

在PTDS(Photonic Transmission Design Suite)仿真平台上,模拟了四通路波分复用系统的运行,对四通路OADM系统的输入信号、下路信号、输出信号进行了光谱分析。显示多通道传输过程的功率一致和信道隔离恰当,以及由于分插复用器件的使用出现的附加损耗。

Simulate the 4 accesses fiber-grating OADM by using PTDS. And analyze the sign about input ,output, taking out sign. The numerical result show that sign power is balance; the adjacent isolation is fitness; the insert excess loss arises because of the OADM.
