Abstract

A method includes generating a sequence of multiple optical pulses, for transmission into an optical fiber (12) having an array of multiple equally spaced reflectors (14) embedded therein, the sequence having a pulse duration and a pulse repetition interval (PRI) that guarantee that reflections of any of the optical pulses from any of the reflectors do not overlap. The sequence of optical pulses is transmitted into the optical fiber. The reflections of the optical pulses from the reflectors are extracted from the optical fiber. One or more events affecting the optical fiber are identified by analyzing the reflections.
