摘　　要：在掺铒光纤放大器（EDFA）内部将增益箝制在增益谱平坦区，研制成增益箝制的EDFA，实现了波分复用（WDM）8×2．5Gb／s×450kmG．652光纤级联放大传输系统的动态增益均衡，在传输信道数量改变的动态运行情况下，在误码率为10－12时，接收机灵敏度变化0．5dB。An erbium-doped fiber amplifier (EDFA) gain-clamped to a flat gain spectral region was designed and built up. The dynamic gain equalized transmission over an 8 × 2．5Gb/s ×450 km WDM system with a G．652 fiber was demonstrated by using cascaded gainclamped EDFAs. When the channel number changed, the sensibility of the receiver varied　only 0．5 dB at BER of 10-12.
