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.

FEBUS G1-D

FEBUS G1-D Dynamic Distributed Strain and Temperature Sensing

Dynamic Strain and Static Strain/Temperature Monitoring

> Dynamic measurement up to 100 Hz for 500 m fiber length and 50 Hz for 1 km fiber length

> Single Ended

> Optimized for harsh conditions

Easy to install and easy to use

> On demand software and interface development

.

FEBUS G1-D GENERAL PRINCIPLE

FEBUS G1-D device provides Dynamic Strain or Static Strain and Temperature information typically every 1 m along several 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-D, 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
