  • Optical fiber cable based intrusion detection system
    Patent number: 6980108
    Abstract: There is provided an electronic security system for a perimeter structure that incorporates a fiber optic cable secured to the perimeter structure. Typically the perimeter structure is a fence. A light pulse is transmitted down the fiber optic cable. Mechanical attenuation devices disposed at various locations along the fiber optic cable are responsive to intrusion attempts. The mechanical attenuation devices produce measurable attenuations to the light pulse. Using backscattering light detection technology an intrusion attempt and the location of an intrusion is detected.
