论文摘要
现有的未重建海底链接越来越多地升级到当前可用于商业应用程序的最先进的调制格式。通常需要使用三阶代码拉曼放大器。相关的高功率泵的功率波动通过非线性KERR效应在相位调制信号中引起相移。本文档中解释了一种减少这种影响对系统性能的影响的方法。
Existing unrepeatered submarine links are increasingly upgraded to the most advanced modulation format currently available for commercial applications. Quite often the use of third-order codirectional Raman amplifiers is necessary. Power fluctuations of the involved high-power pump induces phase shifts in phase modulated signals via the nonlinear Kerr effects. An approach for reducing the impact of this effect on system performance is explained in this document.
