Abstract

The invention provides an optical fiber online monitoring system, which is characterized in that a set optical detection module receives optical signals transmitted by an optical fiber and carries out conversion, a controller module controls an optical switch module to switch to an optical time domain reflectometer when the optical detection module cannot receive the optical signals, detection for the location of a fault point is carried out immediately, a data packet is transmitted to a next monitoring terminal through a transmitting terminal, and connection detection is carried out. The optical fiber online monitoring system not only can carry out fault positioning in time, but also can improve the fault positioning accuracy, reduce the fault positioning time and reduce the troubleshooting time of the personnel. A GPS module acquires the location of the monitoring terminal, the controller module sends the location of the monitoring terminal and the fault location detected by the optical time domain reflectometer to an external monitoring center through a wireless transmission module, and the information is sent to the maintenance personnel through a GSM module, so that the external monitoring center and the maintenance personnel can also acquire the fault information in time even if in an unattended operation, and measures are taken timely to carry out troubleshooting.

Description

technical field [0001] The invention relates to optical fiber monitoring, in particular to an optical fiber online monitoring system. Background technique [0002] To meet the requirements of optical fiber maintenance and management, it is necessary to provide an optical fiber monitoring system that can automatically monitor the degradation and fault status of the optical fiber, has an alarm function, and can assist the staff in long-term maintenance. The optical fiber online monitoring system is a kind of monitoring the optical power of the optical fiber, judging whether there is a fault in the optical fiber, and detecting the fault point of the optical fiber when a fault occurs. The existing optical fiber monitoring system has the problems of long fault location time and time-consuming troubleshooting, and the economic loss caused by the fault often increases exponentially with the length of the fault repair time. Contents of the invention [0003] The invention provide...
