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 (DSS / DTS)
Dynamic Distributed Strain and Temperature Sensing

FEBUS G1-D

Dynamic strain, static strain and 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

The FEBUS G1-D device provides dynamic strain or static strain and temperature information typically every 1 m along several kilometers of 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
