Abstract
An apparatus and method is disclosed for a fiber optic based fire detection and tracking system. An optical time domain reflectometer (OTDR) interrogates at least one optical fiber with a melting point defining a threshold temperature for fire detection. The OTDR measure the time of flight of a light pulse originating at each optical fiber input end and reflected back to determine the linear position of interruptions along an optical fiber which allows for fire detection and location.
