  • Strain and temperature monitoring
  • Compact and autonomous
  • Single-ended
  • Optimized for harsh conditions
  • Easy to install and easy to use
  • On-demand software and interface development


The FEBUS G1-C device provides strain and temperature information every 1 m along several tens of kilometers of an optical fiber deployed on the infrastructure. This system is specifically designed for services purposes allowing quick and easy Brillouin measurement wherever it is required. The FEBUS G1-C meets the harsh environment requirements with energy saving configuration and single-ended connection to the optical fiber sensing cable.
