摘　　要：本文分析了基于可调光衰减器的功率均衡方案 ,对将均衡点放在节点的输出端和复用器之前情况进行了比较。结果表明 ,从信噪比的角度考虑 。The study of a power equalization scheme based on voltage controlling attenuator is presented in detail in this paper.With our scheme,the equalization point is placed at the output of the whole optical node,with that it is placed before the multiplexers.The companision shows that our scheme is better as far as the SNR is considered simultaneously.
