Modeling of macro-bend losses for single mode fibers with multiple cladding or coating layers is presented. Macro-bend losses for standard single mode fibers (SMF28) are investigated theoretically and experimentally, showing that the inner primary coating layer of SMF28 has a significant impact on the bend losses and most of the radiation field is absorbed in the inner primary coating layer of SMF28. The agreement between theoretical calculations and experimental measurements suggests that the so-called elastooptical correction in modeling is not required for SMF28.
本文提出了具有多个包层或涂层的单模光纤宏弯损耗的建模方法。对标准单模光纤（SMF28）的宏弯损耗进行了理论和实验研究，结果表明，SMF28的内初级涂层对弯曲损耗有显著影响，且大部分辐射场被SMF28的内初级涂层吸收。理论计算与实验测量结果的一致性表明，对于SMF28，在建模中不需要所谓的弹光修正。
