对掺铒光纤放大器（EDFA）的小信号低频响应特性进行了理论和实验研究。调制泵浦激光器导致调制从泵浦到在EDFA中放大的信号的低通传递。在低频下调制并由EDFA放大的信号经历的传递函数类似于超前补偿器的传递函数，超前补偿器具有一个频率零点和一个极点。实验结果验证了理论传递函数的幅度和相位响应。<<ETX>>
The small-signal low frequency response characteristics of erbium-doped fiber amplifiers (EDFAs) are examined theoretically and experimentally. Modulating the pump laser results in a low-pass transfer of modulation from the pump to signals amplified in the EDFA. A signal modulated at low frequencies and amplified by an EDFA experiences a transfer function that is similar to that of a lead compensator, which has one zero followed in frequency by one pole. Experimental results verify both the magnitude and phase response of the theoretical transfer functions.<<ETX>>
