光网络信道功率动态均衡方案的实验研究和数值分析

Experiment Research and Simulation of New Dynamic Equalization Method of Optical Channel in Optical Network

采用了节点隔离的均衡原则 ,提出了用可调谐衰减器对波长信道功率调节的两种方案 ,实验和数值计算表明这两种调节方案容易使各个信道功率差在 1d B以内 .并在此均衡方案下对网络性能进行了数值分析 ,计算结果表明 ,通道设置功率和线路的衰减量对网络规模都有较大的影响 .

The two methods of node equalization is proposed using tunable attenuator based on the equalization principle of node isolation. The range of 1 dB is easily realized by the experiment. The numerical analysis shows that both the path power set in advance and the attenuation on the line will affect the scale of networks.
