Fiber Sensing

The fiber as a distributed sensor

Distributed optical fiber sensing systems — temperature (DTS), strain (DTSS) and acoustic (DAS). Existing fiber becomes thousands of sensors.

[ 01 ] — About Fiber Sensing

The Fiber Sensing challenge

Distributed sensing turns optical fiber into a continuous sensor over kilometers — with no point sensors. It detects temperature, strain and vibration along the whole trace.

Tecnous brings fiber sensing technologies for critical infrastructure monitoring: pipelines, perimeters, energy and civil works.

Monitoring extensive assetsPipelines, lines and perimeters of kilometers are not covered with point sensors.
Early event detectionIntrusions, leaks or deformations require distributed real-time detection.
Cost of point-by-point instrumentationInstrumenting every point is unfeasible; already-laid fiber is the solution.

Three technologies, one single medium

We cover the three modes of distributed sensing over optical fiber.

01
DTS — Temperature
Distributed temperature sensing by Raman reflectometry along the fiber.

02
DTSS — Strain
Distributed strain and temperature sensing by Brillouin reflectometry.

03
DAS — Acoustic
Distributed acoustic sensing for real-time vibration and intrusion detection.
