Large core multimode fiber with high tolerance to coupling misalignment and dust contamination in intra-vehicle networks

This paper introduces an optical power ring model for calculating the efficiency of fiber coupling. The model obtains more accurate results than the Gaussian model. This model compares the coupling efficiency of large core and standard multimode fiber and demonstrates that the tolerance of the large-core multimode fiber to the coupling misalignment and dust contamination is higher than that of the standard multimode fiber.
