ABSTRACT:
A light return loss measurement method and system with an optical time domain reflectometer (OTDR) which displays an output of an arithmetic circuit. The method and system permits measurement of the light return loss over an arbitrary interval of an optical fiber. The system's arithmetic circuit calculates light return loss across a measurement interval set in a display waveform data by dividing a predetermined light return loss and integrating the measured waveform by multiplying the set interval by a light interception correction constant. The integration performed is a quadrature of various sections of an optical fiber. The light return loss measurement method and system also permits easy calibration of the light return loss in the OTDR.
