摘要: 设计了测量光纤耦合损耗的实验装置,测量了多模光纤与光源的耦合损耗、多模光纤与多模光纤在纵向偏移及横向偏移时的耦合损耗,理论上分析计算耦合损耗,实验结果与理论计算有较好的一致性.Abstract: Discussion is made on the design of the measuring equipment of coupling loss in optic al fibers,and the measurement of the loss of light to multimode optical fiber coupling,and fiber to fiber coupling due to ordinate separation or transverce offset;the result is in agreement with the theoretical calculation.
