分析了一种用于差分相移键控（DPSK）信号的全光3R再生器。受噪声影响的DPSK信号首先被延迟干涉仪解调为开关键控（OOK）信号。OOK信号的幅度然后由基于光纤的全光2R再生器稳定。在随后的非线性光纤中，本地产生的光学时钟脉冲由稳定的OOK脉冲进行相位调制，并作为再生信号输出。结果表明，强幅度再生可有效抑制相位噪声
Analysis of an all-optical 3R regenerator for differential phase-shift keying (DPSK) signals is presented. Incoming DPSK signals impaired by noise are first demodulated to on-off keying (OOK) signals by a delay interferometer. The amplitude of the OOK signals is then stabilized by a fiber-based all-optical 2R regenerator. In a subsequent nonlinear fiber, locally generated optical clock pulses are phase-modulated by the stabilized OOK pulses and are output as regenerated signals. It is shown that significant phase-noise suppression is achieved by strong amplitude regeneration
