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 Temperature Sensing

febus t1-r

  • Temperature monitoring
    up to 30 km
  • 0.1 °C measurement repeatability (2σ)
  • Spatial resolution 1 m
  • Easy and robust calibration process
  • User-friendly interface and interoperability


FEBUS T1-R device offers very high performances. It provides temperature information every 1 m along several tens of kilometers of an optical fiber cable deployed on an infrastructure. The device can be connected to any type of multimode fiber optic cable including those adapted to run in harsh environments: high temperature, chemical aggressions, embedded or buried in concrete structures.

The FEBUS T1-R embedded sofware provides easy configuration and multiple visualization capabilities of your data. It is also easily integrable into your own solution.

Furthermore, FEBUS Optics offers, along with its FEBUS T1-R, personalized services such as:

  • Implementation survey
  • Access to raw data 
  • Interoperability with third party solution
  • Fiber-optic deployment (through specialized partner)
  • 3-years warranty included (parts and labor) and optional maintenance plan
