Cascaded Amplification and Gain Response of EDFA with Pump Modulation
摘要
对调制泵浦掺铒光纤放大器(EDFA)的增益响应与级联放大的实验研究表明,EDFA小信号增益对泵浦光调制的幅度和频率响应分别呈现线性与低通(<1 kHz)特性,级联放大为高通(>200 Hz)特性。
Abstract
Gain modulation response and cascaded amplification characteristics of Erbiumdoped fiber amplifiers(EDFAs)are experimentally studied.It is shown that the amplitudeand frequency responses of EDFAs are linear and low-Pass(cutoff frequency less than 1kHz),respectively.The transmission characteristics of the low-frequency modulated linesignal are high-pass(cutoff frequency larger than 200 Hz).
