我们提出了一个新的模型，用于预测多模极限下光纤系统的性能。这是基于光线跟踪，但包括焦比退化（FRD）的半经验描述。我们展示了如何FRD模拟模型。有了这种能力，它可以用来研究各种各样的现象，包括混乱和光的损失接近极限数值孔径。它也可用于预测非圆形和非对称纤维的性能。
We present a new model for predicting the performance of fibre systems in the multimode limit. This is based on ray-‐tracing but includes a semi-‐empirical description of Focal Ratio Degradation (FRD). We show how FRD is simulated by the model. With this ability, it can be used to investigate a wide variety of phenomena including scrambling and the loss of light close to the limiting numerical aperture. It can also be used to predict the performance of non-‐round and asymmetric fibres.
