STI-B Series Brillouin Optical Time Domain Reflectometry / Analyzer

Source: ShinewayTech     Date: 2024-11-06     Read: 133

    Brillouin optical time domain reflectometry/Analyzer (B-OTDR or B-OTDA) is a distributed optical fiber sensing system based on Brillouin scattering technology which can measure temperature and strain along a fiber optic cable. With light as the carrier of signal acquisition and optical fiber as the sensing and communication medium, it has outstanding advantages such as good durability, no zero drift, no live work, anti-electromagnetic interference and large transmission bandwidth. Widely used in submarine cable monitoring and early warning, pipeline leakage, geological settlement, communication and power lines, building structure health and other quasi-static monitoring. The development of long-distance, high-precision Brillouin distributed fiber optic sensor monitoring and early warning equipment, based on the principle of Brillouin temperature stress demodulation, combined with temperature measurement data, carries out temperature stress decoupling, monitors the stress of the uninterrupted operation of the submarine cable, and alarms and locates the stress, which can realize the stress alarm function. It lays the foundation for the monitoring and early warning of mechanical faults such as excavation machinery or ship anchor, and can be widely used in the stress and temperature monitoring of industrial places such as communications and power cables, offshore wind power, drilling platforms, nuclear power safety, and building structural health.

 

Key Features

●High Precision: BOTDA or BOTDR can achieve temperature and strain measurement of optical fibers, with high precision temperature and strain monitoring capabilities.

●Strong Real-time: It can realize real-time monitoring of the stress state of optical fiber and cable, and timely find the deformation and stress of the cable and the change of temperature.

●Easy Installation: It can be directly arranged on the optical cable, easy installation.

●Strong Anti-interference Capability: it has good anti-interference capability and can work normally in harsh environments such as high voltage transmission. In order to expand according to the actual demand, to achieve the monitoring and management of multiple optical cables.

●Strong Scalability: It can be expanded according to actual requirements to realize the monitoring and management of multiple optical cables.

●Remote Monitoring: The stress state of the optical cable can be monitored remotely, and the data transmission and management can be achieved through the Internet, which is convenient for users to carry out remote monitoring and management.

●Data Analysis: The system can analyze and process the collected data, generate reports and early warning information, and provide decision support for users.
