Natural Fiber Span Reflectometer Providing a Virtual Signal Sensing Array Capability

Abstract

The present invention relates generally to the field of time-domain reflectometers. More specifically, it relates to such reflectometers which are a part of a photonic system application in which the object of the reflectometry is a span of fiber which has an interrogation signal launch end and a remote end. The invention enables the provision of a linear array of virtual sensors along the span. One particular type of application toward which the invention is directed is an acoustic security alarm system in which the span serves as a perimeter intrusion monitoring line.
