报道了一种全光DPSK信号再生实验。在再生器中，输入的DPSK信号首先被解调成开关键控信号，然后由2R再生器进行幅度再生，然后用作全光相位调制器中时钟脉冲的相位再调制的控制脉冲。通过使用双向配置的两级光纤级联2R幅度再生器，实现了降低幅度噪声的无损失操作。
An experiment of an all-optical DPSK-signal regeneration is reported. In the regenerator, incoming DPSK signals are first demodulated to on-off-keying signals, then amplitude-regenerated by a 2R regenerator, and subsequently used as control pulses for phase remodulation of clock pulses in an all-optical phase modulator. Penalty-free operation with reduced amplitude noise is demonstrated by the use of a two-stage fiberbased cascaded 2R amplitude regenerator in bidirectional configuration.
