Title: Multimode fiber optic intrusion detection system
Inventor: VOKEY DAVID E
IPC: G08B13/186
Filed: 2004-07-02
Granted: 2012-04-03
Abstract: A method and system of intrusion detection system for a multimode fiber optic cable. A light signal is launched into the cable fiber to establish a narrow spectral width, under-filled non-uniform mode field power distribution in the cable. A  small portion of the higher order signal modes arriving at the remote end of the cable is sampled and monitored for transient changes in the mode field power distribution.  The power distribution changes with physical disturbance of the cable. When those changes are detected as being characteristic of fiber intrusion, the system activates an alarm. This method can sense and alarm any attempt to access the optical fibers in a fiber optic communication cable. In preferred embodiments, the active signal of a multimode optical fiber is monitored for both signal degradation and transient power disturbance patterns that could indicate fiber damage or physical intrusion.  Using adaptive filtering, normal background disturbances from heating/cooling systems, motors, fans and other building systems can be learned and filtered out.
