【Abstract】 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.更多还原
