利用相位编码信号的未来超长距离通信系统的性能可能会受到信号传输过程中产生的噪声的影响。缓解这种噪声的一种潜在方法是使用相敏放大器（PSAs），它已被证明有助于从相位编码信号中去除相位和幅度噪声。最近，我们展示了基于退化四波混频的基于psa的信号再生器可以以网络兼容的方式实现，其中只有（噪声）信号存在于设备输入（黑箱操作）。所开发的再生器还能够同时进行波长转换和多播，本文给出了详细的分析。然而，该方案仅在实验室中对产生的人工噪声进行了测试，并将再生器放置在接收器的前面，而不是在预期更大性能优势的情况下进行了测试。在这里，我们从理论上和实验上解决了这样一个再生器如何在多播模式下方便地操作的重要问题，作为安装的传输光纤链路中的在线设备。我们还研究了该方法的色散容忍度。
The performance of future ultra-long haul communication systems exploiting phase-encoded signals is likely to be compromised by noise generated during signal transmission. One potential way to mitigate such noise is to use Phase Sensitive Amplifiers (PSAs) which have been demonstrated to help remove phase as well as amplitude noise from phase-encoded signals. Recently, we showed that a PSA-based signal regenerator based on degenerate four-wave mixing can be implemented in a network-compatible manner in which only the (noisy) signal is present at the device input (black-box operation). The developed regenerator was also able to perform simultaneous wavelength conversion and multicasting, details/analysis of which are presented herein. However, this scheme was tested only with artificial noise generated in the laboratory and with the regenerator placed in front of the receiver, rather than in-line where even greater performance benefits are to be expected. Here, we address both theoretically and experimentally the important issue of how such a regenerator, operating for convenience in a multicasting mode, performs as an in-line device in an installed transmission fiber link. We also investigate the dispersion tolerance of the approach.
