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).
