分析了掺铒光纤放大器(EDFA)瞬态效应的产生机理,讨论了其对DWDM网的危害,给出了采用抽运源控制法对其进行抑制的实验,从实验结果可以看出此方法对EDFA的瞬态效应确实起到了一定的抑制作用。
The mechanism of EDFA transient effect is analyzed, its harm to DWDM network is discussed, and the experiment of pumping source control method is given. The experimental results show that this method is effective EDFA transient effect does play a certain role in the inhibition.
