Abstract

PURPOSE:In detecting the borken part of an optical fiber of particularly a long length for optical signal transmission, high-sensitivity high-accuracy detection is made possible by changing the modulation frequency of the modulated light entering the optical fier and obtaining the peak of the change in receiving amplitudes.
