Optical cable monitoring system

With the constant evolution of communication technology, a plethora of communication equipment are utilized in communication networks. The diverse formats of such equipment pose significant challenges to effective management. Among the array of devices, optical cables are superior communication signal transmission channels, providing benefits that other media cannot match, including extensive information capacity, high transmission density, and exceptional security. Therefore, optical cables enjoy widespread use in the communication field, playing a pivotal role in communication networks.

The optical cable monitoring system monitors the optical cable to determine the operation of the optical cable. When there is a problem with the operation of the optical cable, it will alarm in time to determine the point of failure, so that the relevant technicians can take relevant technical measures in a timely manner to improve the maintenance of the optical cable. efficiency, reducing maintenance time.

Composition of optical cable monitoring system

The optical cable monitoring system mainly includes the following parts: monitoring center, monitoring station and system terminal.

Monitoring center ------ serves as the central control hub of the system. Its primary function is to receive alerts and send test instructions to the optical switch. It then analyzes the results to pinpoint the fault or malfunction.

Monitoring station------mainly encompasses monitoring components and optical switches, and is split into two parts: monitoring and testing. The monitoring component works to monitor optical cables in real-time, while the testing component is responsible for testing the cables' status.

Monitoring client ------- It is mainly a system terminal including corresponding software. Users can use this terminal to perform all operations, including GIS software, which can easily manage and maintain various system resources.

Monitoring principle

Principle of online optical power monitoring

During the detection process, the working light is initially separated before entering the alarm collection module. This module continuously monitors the working light, providing real-time feedback on the optical fiber transmission information, while allowing for customizable attenuation rates on monitoring channels. In the event of a power drop below a certain level caused by environmental factors, the detection module triggers an alarm message, activating the OTDR to analyze the fault's location and cause by testing the fiber core.

Principle of optical power fiber preparation monitoring

In this alarm module, the offline approach can be utilized to test the backup optical fiber and conduct alarm monitoring at the same time. However, since there is no signal source in the fiber preparation, a light source must be included in the monitoring route during testing. After the testing, the optical power is detected by the test equipment. Generally, when there is a fault or abnormality in the fiber core, the light source signal will be disrupted and weakened. The system then transmits an alarm message and supervises the core wire to identify both the type and location of the fault.

The significance of optical cable monitoring system

1) Intelligent Maintenance: The implementation of an optical cable automatic monitoring system has enabled the transformation of optical cable maintenance from extensive to intensive, realizing a move towards intelligent maintenance that meets the actual needs of the industry.
2) Fast and Accurate Obstacle Location: The monitoring system enables the acquisition of the current transmission status of the optical fiber within just 20 seconds. Precise data analysis greatly improves the accuracy of obstacle location, thereby reducing the repair time.
3) Preventing obstacles: The system can detect the gradual changes in the transmission characteristics of the monitoring line, detect obstacles and hidden dangers in time, and prevent obstacles.

The development of optical communication technology will make the ability of optical fibers to transmit information greater and greater, and line interruption per unit time will cause greater losses. Therefore, the importance of optical cable line monitoring will become more prominent. How to further improve the reliability of optical fiber communications, how to monitor and manage optical cable lines in a more timely and effective manner, accurately capture fault signs, and prevent line blockage have become issues of concern. Therefore, the optical cable monitoring system has become an important factor in the power communication market. A new bright spot and unprecedented development.
