Distributed Fibre Optics Sensor

Overview

iDFOS transmits a series of light pulses into a single length of fibre optic cable and detects changes caused by acoustic pressure at each point along the sensing fibre. The signals are analysed in real time and processed to produce an acoustic activity map along the length of the cable.

This information is used for various applications such as physical security, structural health monitoring, seismic monitoring, oil and gas pipeline monitoring, and well and reservoir monitoring.

idFOS (Fiber Distributed Fibre Optics Sensor) is a cutting-edge solution for real-time security and structural health monitoring, using advanced fiber optic technology to detect stress, vibration, and environmental changes with high precision.

Key Features

• 24×7 Real-Time Monitoring and Detection

  The sensor system operates 24×7 as it does not require interruption in infrastructure and facilities under monitoring.

• Precision Location of Disturbance Events

  The system provides the exact location of any disturbance along the fibre optic sensor line.

• Continuous Sensing of up to 20km Range

  One optical fibre cable delivers a sensing range of up to 20km, negating the need for multiple sensors.

• Simultaneous Detection of Disturbance Events

  iDFOS can detect and monitor various disturbance events concurrently along a single fibre optic cable.

Technology Benefits

• Early Warning Detection

  An early warning detection mechanism via acoustics from fibre optics reduces human and economic losses during disasters.

• Lower Cost of Investment and Downtime

  Standard telecom-grade fibre optics are used for sensing, and a power source is not required at the monitoring site, lowering costs and downtime.

• Ease of Integration with Fibre Optic Networks

  Existing fibre optics in underground and overhead infrastructures can be integrated into a communication and sensing network.

• Low Maintenance for Long-Term Monitoring Applications

  Fibre optics are resistant to extreme mechanical stress, high temperatures and chemical exposure, requiring minimal maintenance.
