Thousands of Koheras low-noise lasers keep large scale data network secure
In the project, NKT Photonics will deliver low-noise Koheras fiber lasers to power the FFT-designed fiber-optic intrusion detection and location system.
The initial network deployment is projected to need in excess of 2,000 Koheras lasers over the next 9-12 months. Additional lasers will be delivered during the seven-year spares and maintenance period following the initial three-year warranty period.
The lasers are the key component in the Distributed Acoustic Sensing (DAS) system that monitors the several thousand km long network. DAS systems of this scale put very high demands on the lasers. They must have very low intensity- and phase noise to enable the maximum distance between system points and ensure incident detection with a minimum of false alarms. Meanwhile, the lasers must be extremely reliable while operating in a harsh and often unpredictable environment.
“This project is a testament to the unrivaled performance and quality of our industrial Koheras low-noise fiber laser platform. We have worked with FFT for many years, and we are proud to be the laser supplier for this important flag-ship project” says Søren Løvgreen, Koheras Product Line Manager.
NKT Photonics is the leading supplier of low-noise lasers for remote sensing and there are more than 10,000 Koheras lasers deployed in applications like pipeline security, seismic monitoring, vibrometry, as well as LIDAR for wind turbine applications.back to overview
