METHOD, DEVICE, AND SYSTEM FOR OPTICAL FIBER LINK IDENTIFICATION

摘要

Embodiments of the present invention relate to the field of communications. Provided are a method, device, and system for optical fiber link identification, for identification of different optical fiber links. The method comprises: a link identification device transmits a first testing optical signal, receives a second testing optical signal returned when the first testing optical signal is transmitted to a connection port of a first optical node, acquires a reflection peak of the second testing optical signal on an optical fiber link, determines a port identifier of the connection port of the first optical node on the basis of the reflection peak of the second testing optical signal on the optical link, and identifies, on the basis of the port identifier of the connection port of the first optical node, an optical fiber link corresponding to the second testing optical signal returned by the connection port of the first optical node. The method embodiment is used for identification of optical fiber links.
