摘　　要：描述了基于数据抽运方案的光纤参量2R(再放大、再整形)再生器(FOPR)工作原理及其设计原则。从简并四波混频(FWM)抽运带宽、连续探测光波长设置以及功率转移函数(PTF)等方面对FOPR进行了仿真设计,指出FOPR中采用功率控制单元提升再生器性能的必要性。在此基础上,制作了一台全光2R再生器,并对其再生性能进行了实验测试,其PTF斜率约为1.7,消光比(ER)可提升约5dB,实验结果与仿真设计一致。The operating principle and design criterion of fiber-optic parametric 2R （re-amplification, re-shaping） regenerator （FOPR） are described based on data-pump solutions. A FOPR is designed by simulation from degenerate four-wave mixing （FWM） pump bandwidth, wavelength configuration of the probe continuous wave, and power transfer function （PTF）, and the necessity of using the power control unit in FOPRs to improve regenerator performance is also pointed out. Then, an all-optical 2R regenerator is developed and the experimental measurement for the regenerability is done. The measurement results show that, the PTF slope is about 1.7 with the extinction ratio （ER） improvement of about 5 dB, and the exoerimental data are consistent with the simulation results.
