摘要
介绍测试塑料光纤衰减的三种方法:截断法、插入损耗法和后向散射法。详述各方法的测试原理及所用装置,重点分析三种方法的特点、差异,提出测试中应注意的问题。
Three attenuation measuring methods for plastic optical fiber including the cut-back method, the insertion-loss method and the back-scattering method are introduced. The measuring principles and apparatus used in tests are presented in detail. The characteristics and the main problems that should be noticed in test procedures for three methods are emphatically discussed.
