提出了一种新型的基于数据抽运的光纤光参量放大(FOPA)的多波长(4×40 Gb/s)全光3R再生实现方案。与已有的利用光参量放大技术再生不同的是，所提方案利用4路恶化的数据信号作为抽运光，同时，分析了其再生机理。实验结果表明，对于“1”码和“0”码的噪声均有较好的抑制。利用波长变换和高Q值(1000)的法布里珀罗(F-P)滤波器进行时钟提取，得到均方根(RMS)抖动仅为180 fs的高质量时钟。在多波长全光判决部分，采用了正交极化和双向注入的方法来抑制4个恶化信号之间的相互串扰。最终实现了4路信号的信噪比改善值分别达到2.21、2.79、2.72和1.99的再生实验。

A novel scheme of multi-wavelength (4×40 Gb/s) all-optical 3R regeneration is presented by using a fiber optical parametric amplifier (FOPA) with degraded data signals as the pump, which is different in mechanism from previous regeneration schemes. It is demonstrated that, this scheme restrains the noise on both "1" bit and "0" bit very well. The clock extraction is based on wavelength conversion and a Fabry-Perot (F-P) filter with a high Q value of 1000. And the jitter of the recovered clock is only 180 fs. In the multi-wavelength decision unit, the orthogonal polarization as well as bidirectional injection is employed to avoid crosstalk among the four degraded signals. Finally, this scheme realizes that, the signal to noise ratios of the four regenerated signals are improved by 2.21, 2.79, 2.72, 1.99 respectively.
