METHOD AND OPTICAL CABLE TRACKING DEVICE FOR MEASURING OPTICAL CABLE DISTANCE BY USING OPTICAL CABLE TRACKING DEVICE

摘要

The present invention relates to an optical cable tracking device and a method for measuring an optical cable distance by using the optical cable tracking device. The optical cable tracking device comprises a light source, an optical coupler, a phase modulator, delay optical fiber, and an optical signal demodulation module. The present invention distinguishes cables according to the interference generated between optical lines in an optical cable by tapping the optical cable. The present invention conveniently inspects and maintains the optical cable by determining the distance between a tapped point and a telephone office.;COPYRIGHT KIPO 2014;[Reference numerals] (1) Light source;(2) Light coupler 1;(5) Light coupler 2;(6) Measuring target light cable
