• High channel count multi-component fibre-optic sensor array
• Designed for high reliability and robustness
• Proprietary optical architecture for maximum channel count per fibre and minimum number of optical components
• Lightweight cable and sensor packaging for safe, efficient deployment

The Fosar® system consists of a passive, fully fibre-optic array of Optical Sensor Units (OSU) connected by armoured fibre optic cable.

The array is installed subsea and connected through a riser to an interrogation device at the surface that communicates with the sensors by pulsing light into the array and receiving and decoding the returning signals.
