Optical cable fault alarm system

Abstract

The invention discloses an optical cable fault alarm system which comprises a control unit, an optical power monitoring unit, a first light source unit and an alarm unit. The optical power monitoringunit is used for receiving an optical power monitoring instruction of the control unit, monitoring the optical power information of the optical cable through a monitoring process and feeding back theoptical power information to the control unit; the first light source unit is used for providing a monitoring light source for the optical power monitoring unit; and the alarm unit is used for performing alarm operation on the abnormal optical power information received by the control unit. According to the invention, the whole optical cable line can be monitored remotely and online, the change and the change trend of the optical fiber characteristics are monitored in real time, the faults can be found timely to alarm, and the optical cable faults can be reduced and prevented effectively. According to a fault point positioning method of the present invention, the fault point coordinates of the faults of the optical cable can be determined accurately, the fault query and the elimination time can be shortened, the workload of maintenance personnel can be reduced, and the work efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of communication optical cable monitoring and alarming, in particular to an optical cable fault alarming system. Background technique [0002] Generally, communication optical cables are used for long-distance transmission. Whether it is laid overhead or buried, the environment around the line is more complicated, and the optical fiber is more sensitive to environmental influences, such as pollution of optical fiber connectors, damp pigtails, and man-made and natural damage. These will cause the fiber to break, causing the communication line to be interrupted. At the same time, in real production and life, due to frequent natural disasters such as artificial construction, road relocation or natural earthquakes, tsunamis, mudslides, etc., fiber optic cable failures may occur every day, resulting in communication interruptions, seriously affecting the normal work of the communication network, causing huge Eco...
