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.

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


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 specialized partner)
  • On-demand specific analysis modules and customized GUI (Guided User Interface)
  • Interoperability with SCADA or equivalent
  • 3-years warranty (parts and labor) and optional


Acquisition frequency Up to 100 Hz (50 microns/m repeatability at 500 m)
Sampling interval From 0.1 m to 20 m
Spatial resolution

From 1 m to 20 m

Measurement repeatability Down to 0.1°C or 2 microns/m
