Optical fiber location judgment method

Abstract

The invention relates to an optical fiber location judgment method. The optical fiber location judgment method includes the following steps that an optical fiber inquiry software is installed on a mobile terminal, and the optical fiber inquiry software is connected with a background inquiry system; the optical fiber inquiry software inputs an inquiry instruction, and the inquiry instruction includes information of an optical fiber to be inquired; the optical fiber to be inquired is bent, and certain attenuation occurs at a bent section; the background inquiry system real-timely scans and compares user side receiving optical power values of all ports which share the same passive optical network (PON) port with the optical fiber to be inquired, detects whether the optical power value of each port changes or not within a relative time period and sends relevant inquiry information to the mobile terminal, and optical fiber location judgment can be achieved. The optical fiber location judgment method has the advantages that various communication optical fibers can be real-timely monitored, routes and relevant attributes of the optical fibers are judged, the mounting and maintaining efficiency is greatly increased, human errors are avoided, and communication safety is guaranteed.

Description

technical field [0001] The invention relates to the field of optical fiber communication, in particular to an optical fiber positioning and judging method. Background technique [0002] At present, optical fiber technology is developing rapidly and has been widely used in various fields, especially in the field of fiber-to-the-home communication. However, the rapid increase of optical fibers and optical paths has brought difficulties to resource management. Thousands of optical fibers It is difficult to judge on-site in the optical fiber distribution box and fiber splitter box, which is the so-called "dumb resource" problem of optical fiber. At present, the visual fault detector is often used to locate and judge the optical fiber. Red light is used to judge the optical fiber visually. For the optical fiber in use Communications must be interrupted, and operations are difficult and inefficient. Contents of the invention [0003] The technical problem to be solved by the pr...
