Abstract

本申请提供了一种光时域反射仪及具有光时域反射功能的光组件，该光时域反射仪包括一个底座，该底座上设置有分光膜片，该分光膜片上相对的两侧分别为透射区及反射区；还包括第一激光器及探测器，且所述第一激光器及所述探测器分别位于所述分光膜片的两侧；并且第一激光器发射的激光通过所述分光膜片反射出所述底座，光纤中反射或者散射的激光透过所述分光膜片后照射入所述探测器。通过上述描述可以看出，在采用第一激光器与探测器封装在一个组件中时，通过一个组件既可以实现探测激光的发射，同时也可以实现探测激光的接收，即通过一个部件即可完成整个探测工作，便于光时域反射仪的小型化发展，极大的减少通信系统中的光时域反射仪占用的空间。
