Claim:
1. A system for protecting a border comprising: a fiber-optic cable extending from one end of a border to the other end of the border regardless of the terrain encountered along the length of the border, the cable being installed beneath a surface of the ground substantially throughout the length of the border, and the cable including a bundle of optical fibers extending the length of the cable; sensors installed at locations along the border for detecting an incursion or intrusion of the border, each sensor being connected to optical fibers of the cable; and, the cable further including a high voltage conductor also enclosed within the cable and extending throughout the length of the cable and by which high voltage AC is introduced into, and passes through the entire length of the cable for powering the sensors regardless of the sensor's location along the length of the cable, the provision of the high voltage conductor allowing power to be supplied to the sensors regardless of the sensors' location along the length of the cable and eliminating the need for other sources of power located anywhere along the length of the border; and, wherein the high voltage AC introduced into and passing through the fiber-optic cable is approximately 13,300 volts with the fiber-optic cable supplying all of the power required to power the sensors wherever the sensors are located along the length of the cable, and the fiber-optic cable further communicating outputs from each sensor, wherever located along the length of the cable, to a processing location where a sensor's output is evaluated and a threat assessment made with respect to a detected incursion.
