What is Fiber Optical Cable Monitoring System

Introduction
The fiber optical cable monitoring system monitors the fiber optical cable and then judges whether the optical cable is in normal operation; when the abnormal situation occurs, alarms will be issued and corresponding tests will be sent. In addition, through the judgment of fault data the position where fault occurred can be accurately located, the faulty equipment and the reason causing the fault can be quickly ascertained.

The implementation process of the optical cable monitoring system is divided into three parts: information collection, summary and analysis, evaluation and diagnosis of equipment operation. Information is collected so that workers can know the status of monitoring status well.

The function of data collection will be lost if the collected data is not summarized and analyzed, the problems reflected by the data will not be found, and the internal rules will not be revealed, making it difficult to implement monitoring.

Evaluate and diagnose equipment performance. Since monitoring is the most basic maintenance activity, the ultimate goal of maintenance is to be able to evaluate and diagnose.

Structure
The optical cable monitoring system is mainly composed of monitoring center, RTU remote testing station and operation terminal. The remote monitoring station mainly includes optical time domain reflectometer OTDR, optical power monitoring OPM unit, optical switch OSW, etc. It is divided into monitoring unit and testing unit. The former mainly monitors the cable information, the latter mainly test the running status of cable. The Monitoring center is located in the control center of optical cable monitoring system, including monitoring network management systems and servers. The main function is to send test and switching commands to the optical time domain reflectometer and optical switch according to the received alarm from the tube power monitoring unit, and to accurately analyze and determine the fault point according to the feedback test results.

The operation terminal is the user’s operation terminal for the whole system, including the PC terminal and corresponding software, which mainly provides convenient conditions for the user to maintain the line and find the fault point.
