Analysis of multimode fiber impulse response simulation models

Abstract

The widespread deployment of optical interconnects in data centers has renewed the interest in multimode fiber communications. Due to the complexity of modern transmission techniques, performance analysis relies on numerical simulations that require an accurate channel model to reflect reality with the needed precision. As there is no standard model for channel simulation, we investigate a deterministic, a statistical and the Cambridge 108 Fiber model for derivation of the multimode fiber (MMF) impulse response. Numerical simulations are performed in order to calculate the 3-dB bandwidth for each model. We show that the Cambridge model is generally a compromise between the statistical and the theoretical model, which seem to represent a pessimistic and an optimistic scenarios, respectively.
