Abstract

Based on the measurement principle of optical time-domain reflectometry (OTDR), a method to improve the nonreflection-event locating accuracy is proposed. With this method, the experimental data collected by OTDR have been retreated and the locating accuracy has been increased by using injection pulse rising edge.
