| Abstract(in English) | In EDFA, to suppress transient response at a change in the number of input signals, the high-speed AGC circuit has been developed. The two control methods have been also proposed for suppression of transient response. One is a method of changing pump power before the input power changes by inserting a delay fiber between input monitor and EDF. The other is a method of changing pump power to make the output power flat according to the evaluated output power change against input power change. In this report, first of all, we show the transient response generation theory of EDFA at input signal change. Next, we have improved the fiber parameter of EDF, and evaluated the effect on the transient response. |
