Abstract

PURPOSE:To detect the broken part of an optical fiber within a short time by entering sine wave modulated light into an optical fiber to be used in an optical communication apparatus by sweeping modulation frequency at a constant speed and counting the number of the ampli tude changed waves of a receiving signal.
