论文摘要
我们展示了如何将增强的高斯噪声（EGN）模型扩展到沿光纤链路放置的光学设备的极化依赖性损耗（PDL）。我们提供了一个全面的理论，强调了在纤维非线性KERR效应和放大自发发射的情况下的时间，频率和极化域之间的关系。我们通过拆分型傅立叶方法（SSFM）模拟对新模型进行仔细检查，显示出非常好的精度。可以有效利用该模型，以估计PDL引起的停电概率的低值，计算时间比SSFM快的计算时间顺序，从而在光学通信链路的设计中打开了新的机会。
We show how to extend the enhanced Gaussian noise (EGN) model to account for polarization-dependent loss (PDL) of optical devices placed along a fiber-optic link. We provide a comprehensive theory highlighting the relationships between the time, frequency, and polarization domains in the presence of fiber nonlinear Kerr effect and amplified spontaneous emission. We double-check the new model with split-step Fourier method (SSFM) simulations showing very good accuracy. The model can be efficiently exploited to estimate low values of outage probabilities induced by PDL with computational times orders of magnitude faster than the SSFM, thus opening new opportunities in the design of optical communication links.
