我们证明，第一次，我们的知识，再生的42.66 Gb/s的差分相移键控信号使用双泵浦非简并四波混频为基础的光纤参量放大器。该子系统的再生性能的特点是对窄带和宽带引入噪声的误码率。虽然一个强大的接收机灵敏度的改善，高达20 dB，注意到对窄带噪声，对准随机（宽带）噪声，我们观察到再生2.7 dB。
We demonstrate, for the first time to our knowledge, regeneration of a 42.66-Gb/s differential phase-shift keyed signal using a dual-pump nondegenerate four-wave-mixing-based fiber-optic parametric amplifier. The regenerative performance of the subsystem is characterized in terms of bit-error rate against narrowband and wideband introduced noise. While a strong receiver sensitivity improvement, up to 20 dB, is noticed against narrowband noise, against quasi-random (wideband) noise we observe a regeneration of 2.7 dB.
