Introduction to the Optical Fiber Sensing and Optical Monitoring Systems

Products of the Optical Fiber Sensing and Optical Monitoring Systems

OTDR Fiber Auto-Monitoring System

OTDR (Optical Time Domain Reflectometer) Fiber Auto-Monitoring System is used for monitoring systems in optical communication network maintenance. It utilizes backscattered light generated during fiber propagation to analyze attenuation and detect faults.

Distributed Fiber Optic Temperature Sensing System (DTS)

Distributed Fiber Optic Temperature Sensing System is used for real-time temperature monitoring along optical fibers. It applies Raman scattering and OTDR technology to detect temperature changes and accurately locate fire hazards in long-distance and hazardous environments.

Distributed Acoustic Sensing System (DAS)

Distributed Acoustic Sensing System is used for continuous acoustic and vibration monitoring along optical fibers. Based on coherent OTDR technology, it detects sound waves and micro-strain with high sensitivity for long-distance distributed sensing applications.

Optical Fiber Distributed Vibration Monitoring System （DVS）

Optical Fiber Distributed Vibration Monitoring System is used for continuous vibration monitoring and precise event localization along optical fibers. It enables real-time detection of vibration signals for perimeter security and infrastructure protection.

Features of the Optical Fiber Sensing and Monitoring Systems

Distributed and Real-Time Measurement

Through optical fiber sensing, multiple events along the same fiber can be monitored simultaneously, enabling 24/7 distributed detection of vibration, temperature, and strain without signal interference.

High Sensitivity and Accuracy

Fiber-based sensing enables detection of minor physical changes with millisecond-level or faster response, supporting accurate event identification and localization.

Wide Coverage and Long Distance

Supports distributed fiber sensing with DTS coverage up to 25 km and DVS/DAS coverage up to 50 km, enabling large-area infrastructure monitoring over long-distance optical fiber links.

Intelligent Monitoring and Early Warning

Advanced algorithms support real-time analysis, anomaly recognition, and alarm generation via Web, SNMP, or graphical interfaces, reducing reliance on manual inspection..

Flexible Deployment and Modular Design

Modular sensing units and boards allow flexible system expansion and seamless integration with existing optical fiber infrastructure.

Rugged and Intrinsically Safe

Fiber-based sensing ensures operation in harsh environments (heavy snow, flood, and lightning) without electrical hazards or interference, ensuring reliable long-term operation.

Applications of the Optical Fiber Sensing and Monitoring Systems

The Optical Fiber Sensing and Monitoring Systems are widely deployed across diverse scenarios where large capacity, long reach, and operational reliability are essential.
