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.
