A method of monitoring a temperature condition includes inputting a light pulse into a fiber optic cable and receiving a reflection signal that arises from said input light pulse in said fiber optic cable. A temperature condition along the fiber optic cable and a location of the temperature condition along the fiber optic cable is determined based on said reflection signal.
