Optical fiber based sensor system for monitoring of infrastructures

Febus Optics is an innovative company based in Pau (France) bringing a new generation of optical fiber based sensor system to the market, in particular for the maintenance and monitoring of infrastructures.

Distributed Strain and Temperature Sensing

FEBUS G1-R Distributed Strain and Temperature Sensing

> Strain and Temperature Monitoring

> Unique measurement speed: 1km/1s measurement

> Single Ended

> Optimized for harsh conditions

Easy to install and easy to use

> On demand software and interface development



FEBUS G1-R device provides Strain and Temperature information typically every 1 m along several tens of kilometers along an optical fiber deployed on the infrastructure. This system is specifically designed to meet harsh environment requirements with energy saving configuration and single- ended connection to the optical fiber sensing cable.

Furthermore, FEBUS OPTICS offers, along with its FEBUS G1-R, personalized services such as

> Implementation survey
> Fiber-optic deployment (through experienced partner)
> On demand specific analysis modules and customized GUI (guided user interface)
> Interoperability with SCADA or equivalent
> 2-years guaranty (part and labor) and optional
