摘要
介绍了OTDR基本原理,比较分析了目前的几种实现方式,重点结合PON ODN的需求和OTDR自身能力,提出OTDR基本参数和测试性能的指标建议,同时根据典型的ODN场景以及需要检测的反射和衰减事件,对OTDR反射事件和衰减事件的检测指标进一步进行量化并给出具体建议。
The basic principles and current implementation ways of OTDR were analyzed, and the requirements of PON ODN with the capability of OTDR itself were combined to propose the suggestions on basic parameters and test performance requirements of OTDR. Furthermore, according to the need to detect the reflection and attenuation events in some typical ODN scenarios, the capability targets of detecting these events were suggested in detail.
