【Abstract】 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.更多还原
