一、光纤接续损耗分析1、光纤接续损耗产生的原因(1)本征损耗本征损耗是光纤材料所固有的一种损耗,预制棒拉丝成纤后就确定了,这种损耗无法避免,引起光纤本征损耗的主要原因是散射和吸收,散射是由于材料密度不均匀而产生的瑞利散射,吸收主要是光纤材料中的杂质粒子对某些波长的
First, the optical fiber splice loss analysis 1, the optical splice loss causes (1) the intrinsic loss The intrinsic loss is a loss inherent in optical fiber materials, preform rod drawing is determined after the fiber, this loss can not be avoided, causing The main reason for the intrinsic loss of optical fiber is scattering and absorption. Rayleigh scattering due to the uneven density of the material absorbs mainly the impurity particles in the optical fiber material to certain wavelengths
