针对单纤双向光信号放大的光纤传感领域,设计了基于光开关的掺铒光纤放大器。介绍了双向掺铒光纤放大器的光路原理和电路原理,并进行了样机的实现实验。通过实验测试,实现了光信号的分时复用双向放大,双向增益一致性小于0.9dBm。

For single fiber bidirectional optical signal amplification in the field of fiber sensor, the bidirectional erbium doped fiber amplifier （EDFA） based on optical switch is designed. In the paper, the optical path principle and circuit principle of the bidirectional EDFA are introduced. Through the experimental test, the optical signal is amplified by time division multiplexing and the bidirectional gain is less than 0.9dBm.
