Fencing Fiber Wire

A security system is described that includes an optical fiber net woven from an optical fiber wire. A light generator introduces an incident light signal into the optical fiber wire. A light receiver receives an exigent light signal from the optical fiber wire. An optical sensor wire is connected to the optical fiber net and is displaced when a force is applied to the optical fiber net. The optical sensor wire receives a patterned incident light signal that is altered upon application of the force applied to the optical fiber net, thereby producing an altered patterned exigent light signal. The light receiver initiates an alarm either (1) if the exigent light signal from the optical fiber wire terminates, or (2) after comparing the exigent patterned light signal with the incident patterned light signal in the optical sensor wire and establishing a deviation, if the deviation exceeds a predetermined threshold
