摘要
用速度观点，分析了多模光纤弯曲损耗的物理本质据射线理论分析了弯曲对光纤内传播的光线及光纤数值孔径的影响。
Physics inherentence of losses in bending is analysed by velocity viewpoint Influence of bending on propagating ray and numerical apeture in fibers are an alysed by ray theory, and mathematical expression of losses in bending of mu lti-mode fibers is led out by electromagnetic theory
