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

  • Strain and temperature monitoring
  • Unique measurement speed: 1 km/1 s measurement
  • Single-ended
  • Optimized for harsh conditions
  • Easy to install and easy to use
  • On-demand software and interface development


The FEBUS G1-R device provides strain and temperature information typically every 1 m along several tens of 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-R, 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
