摘要
介绍了几种光回波损耗的测量原理和测量方法。针对大量光纤器件的回波损耗实际测量需求,提出了基于光时域反射技术的解决方案,并给出了该方案实现所需的一些关键技术和实用电路。
Several kinds of measurement principles and methods for optical return loss (ORL) are introduced. Against the actual measurement demand on large amount of fiber optic devices the solution based on OTDR technique is proposed, and some necessary key techniques and practical circuits for realizing this scheme are given.
