Abstract
There is provided a method, system and computer program for detecting duplicate OTDR measurements performed on a same fiber. It is determined whether OTDR traces are likely to have been acquired over the same optical fiber link by comparing the backscattering pattern associated with a given fiber span along the OTDR traces, which corresponds to a continuous optical fiber section.
