NEC and OFS Demonstrate Intrusion Detection using AcoustiSens® Enhanced Rayleigh Backscattering Enhanced Fiber in Telecom Cables as Sensing Backhaul


NEC and OFS are pleased to report field test results of facility perimeter intrusion detection with distributed-vibration-sensing technology and AcoustiSens Rayleigh backscattering-enhanced-fiber with deployed telecom fiber cables as sensing backhaul. Various intrusive activities, including walking and jumping, are detected at greater than 100 feet (30.5 meters) from the perimeter of the cable. The use of AcoustiSens backscattering-enhanced fiber enables the use of existing telecom fiber to backhaul signals from remote sensing installations….an order of magnitude increase in backscattering over telecom-grade fiber.

"The ability to identify operational threats from a distance is key to the security of our nation's critical infrastructure," said Dr. Kathleen Kiernan, President of NEC National Security Systems. "NEC's Intelligent Optical Fiber Sensing solution increases and improves the ability to monitor the millions of miles of ubiquitous, invisible fiber optic cable that transmits all manner of information that is essential to the well-being of our global community."
