我们数值研究的2R再生技术，利用自相位调制和偏心滤波。我们的数值模拟考虑到通过其频谱表示噪声的不相干性。这种方法允许评估该再生器的2 dB的Q因子改善。此外，我们的研究指出了输入和输出滤波器的再生器的作用。我们表明，输入滤波器必须适当地选择，以获得最佳的Q因子的改善。为了保持调制格式，还必须适当地选择输出滤波器。
We numerically investigate the 2R-regeneration technique utilizing self-phase modulation and off-center filtering. Our numerical simulations take into account the incoherent nature of noise through its spectral representation. This approach allows to evaluate a Q-factor improvement of 2 dB for this regenerator. Furthermore, our study points out the role of both the input and the output filter of this regenerator. We show that the input filter must be suitably chosen in order to obtain the best Q-factor improvement. The output filter must also be suitably chosen in order to preserve the modulation format.
