Distributed Fiber Optic Sensing (DFOS) is a technology that allows the monitoring of physical parameters along the length of an optical fiber in real-time. It transforms standard optical fibers into long and continuous sensors, enabling the measurement of various environmental and structural conditions. DFOS systems are widely used in industries such as oil and gas, civil engineering, transportation, and environmental monitoring.

Employing Telecom Fiber Cables as Sensing Media for Road Traffic Applications

/in /by

Distributed fiber optic sensing systems (DFOS) allow deployed fiber cables to be sensing media, not only dedicated function of data transmission. The fiber cable can monitor the ambient environment over wide area for many applications. We review recent field trial results, and show how artificial intelligence (AI) can help on the application of road traffic monitoring. The results show that fiber sensing can monitor the periodic traffic changes in hourly, daily, weekly and seasonal.

Field Trial of Cable Safety Protection and Road Traffic Monitoring over Operational 5G Transport Network with Fiber Sensing and On-Premise AI Technologies

/in /by

We report the distributed-fiber-sensing field trial results over a 5G-transport-network. A standard communication fiber is used with real-time AI processing for cable self-protection, cable-cut threat assessment and road traffic monitoring in a long-term continuous test.
