Abstract
A method for detecting branch fibers is provided, which includes: sending test signals to a plurality of branch fibers, where the test signals are added at ports of the optical splitting module with identification information for identifying branch fibers connected to the ports and receiving a reflection signal added with the identification information of a detected branch fiber, identifying the detected branch fiber corresponding to the reflection signal through detecting the identification information added to the reflection information, and obtaining channel characteristics of the detected branch fiber according to the reflection signal. Further, a system and an apparatus for detecting branch fibers are provided.
