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 Acoustic Sensing

FEBUS A1-R Distributed Acoustic Sensing

> Vibration Monitoring

> Single-ended

> Phase and amplitude monitoring

> Easy to install and easy to use

> Optimized for harsh conditions

> On demand software and interface development



FEBUS A1-R device provides Acoustic sensing typically every 2 m along several tens of kilometers with optical fiber cable deployed on the infrastructure. The FEBUS A1-R device can be connected to optical fiber cables already in place. The only requirement is for the optical fiber to be single-mode. This system is specifically designed to meet harsh environment requirements with single-ended connection to the optical fiber sensing cable.

Furthermore, FEBUS OPTICS offers, along with its FEBUS A1-R, 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
