| Abstract: | One of the key problems on the nonreflective event locating accuracy is tomake a reasonable judgment based on the collected data with OTDR,In this paper,suchproblem has been discussed,and a efficient method has been presented. The method proposed here is suitable for the cases of both good signal-noise ration and poor signal-noiseratio. |
