FOGrid: FEBUS Optics' cable monitoring solution applied to an offshore wind turbine farm
CABLE MONITORING USING DISTRIBUTED FIBER OPTIC SENSING
FOGrid is FEBUS Optics' comprehensive and easy to deploy solution to ensure a continuous real-time monitoring of the integrity of buried or overhead cables, whether offshore or onshore.
FEBUS' distributed fiber optic sensing devices use a single mode optical fiber already present in the cable. Based on reflectometry, FEBUS interrogators only need to be connected to one end of the fiber. This way, the deployment of our cable monitoring solution is simplified.
Our interrogators address long distances (several tens of kilometers) while providing spatially continuous measurements. By coupling with our REM (Range Extension Module), the range increases and investments are optimized as less interrogators are required for complete cable network coverage. Additionally, if a break occurs in the fiber length, measurements are taken up to the point of breakage.
Our devices FEBUS A1 (Rayleigh, DAS - Distributed Acoustic Sensing), and FEBUS G1-R (Brillouin, DTS - Distributed Temperature Sensing) provide with precise, reliable, and accurately localized data.
Continuous monitoring over the entire length of the cables is ensured.
- Thermal monitoring of the cable with the FEBUS G1-R
- Detection of any fault with the FEBUS A1

FEBUS CABLES MONITORING APPLICATIONS
MONITOR THE INTEGRITY OF POWER CABLES
FOGrid, a distributed fiber optic sensing solution for cable monitoring, offers integrity control of a power cable during its deployment and all along its operation. Any failure or risk occuring on or near the cable is detected in real-time: suspicious temperature changes, third-party intrusion, cable strain. An alert with the precise location and nature of the event is generated. The cable lifespan is optimized.
MONITORING OF TELECOMMUNICATION CABLE
FEBUS Optics' telecom cable monitoring solution performs continuous spatial and temporal measurements and provides real-time accurate data on the cable fatigue, its potential optical losses, and third-party intrusions. Any failure is quickly detected to promptly initiate a maintenance operation.
PARTIAL DISCHARGE DETECTION
The FOGrid solution from FEBUS Optics enables real-time and continuous detection of cables partial discharges. An alert is instantaneously generated, indicating the precise location of the incident on a geolocated map.
ENVIRONMENTAL MONITORING
Cables can be an environmental monitoring tool. FOGrid, a cable monitoring solution, provides information on temperature changes, seismic activity and underwater acoustics. These data help to better understand our environment.
MONITORING OF DYNAMIC CABLES
Based on our interrogators state-of-the-art performance and dedicated algorithms, FOGrid is a solution for monitoring and estimating fatigue and temperature of dynamic cables. The lifespan of these sensitive and critical parts is optimized.
REAL-TIME THERMAL RATING
FOGrid allows coupling of cable integrity monitoring with RTTR (Real-Time Thermal Rating). This advanced modeling technique provides key information on the cable to estimate its maximum electrical load threshold above which it may be damaged.
OPTIMIZING CABLE MONITORING INVESTMENTS WITH FEBUS SOLUTION
FEBUS Optics interrogators enables rationalized investments, whether in purchasing than during maintenance operations, by covering long distances.
The FEBUS A1 (DAS - Distributed Acoustic Sensing) and the FEBUS G1-R (DTSS - Distributed Temperature and Strain Sensing) can address up to 100 kilometers of cable.
To cover longer distances, FEBUS interrogators can be combined with the FEBUS REM (Range Extension Module) to extend their range. The entire installation is thus controlled at minimal cost and maintenance expenses are reduced.
