基于高非线性光纤SPM(自相位调制)效应加偏移滤波的全光再生技术，分析了级联再生器在输入脉冲宽度、光纤参数和滤波器带宽一定的情况下，输入信号功率和滤波器偏移量对输入信号幅度抖动和Q值的影响。数值仿真结果表明：优化后的输入信号功率和滤波器偏移量使得级联再生后的信号幅度抖动和寄生脉冲都得到了抑制。第2级再生后的Q值改善值比第1级再生后最大提高了2 dB。

On the basis of the all-optical regeneration technology for Self-Phase-Modulation (SPM) effect and offset filtering in highly nonlinear fibers, we analyze the effects of the input signal power and filter wavelength offsets of the cascaded regenerator on the input signal amplitude jittering and Q values when the input pulse width, fiber parameters and filter bandwidth are constant. Numerical simulation results indicate that the optimized input signal power and filter offsets suppress both the cascaded signal amplitude jittering and spurious pulses and the second-stage regenerated Q value is improved by as much as of 2 dB than the first-stage regeneration.
