本文研究了SDM系统中产生的非线性干涉噪声（NLIN），并将单模光纤中的NLIN模型推广到多模光纤中。广义模型考虑了NLIN的调制格式依赖性，并给出了NLIN功率随传输模式数量的缩放。它还提供了用于将NLIN向导的结果扩展到SDM的工具。与单模系统的情况不同，在SDM情况下，MD的影响通常不能忽略。我们发现，包括MD擦除的贡献FWM效应，并显着抑制XPM的效果。
We study the nonlinear interference noise (NLIN) generated in SDM systems, and generalize the NLIN model introduced in the context of single-mode fibers to the multi-mode case. The generalized model accounts for the modulation-format dependence of the NLIN, and gives the scaling of the NLIN power with the number of transmitted modes. It also provides the tools for extending the results of the NLIN Wizard to SDM. Unlike in the case of single-mode systems, the effect of MD cannot in general be ignored in the SDM case. We show that inclusion of MD erases the contribution of FWM effects, and significantly suppresses the effect of XPM.
