Abstract
A fiber optic security sensor cable and system for using the cable. The cable includes a optical fiber encased in a first jacket, a power cable encased in a second jacket, and an overjacket encasing both the first jacket and the second jacket where the fiber is utilized to securely transmit data and provide a response to a sensed disturbance to the sensor cable. The system provides secure data transmission and power distribution via the sensor cable where one optical sensing fiber along the path of a data fiber responds to a sensed disturbance to the sensor cable. The system's sensor cable is enabled to detect disturbances at a processing unit where the sensor cable is either physically routed adjacent to the processing unit or within the processing unit. The system can further include more than one processing unit in the form of auxiliary units such as repeaters, power amplifiers, power outlets, data routers, and any similar electronic device. The system can also include a plurality of processing units which are arranged along the data path, wherein the sensor cable is physically routed within at least one of the processing units. The system's processing units may include at least one that is a microprocessor based signal processor.
