Abstract
The invention relates to a method of determining at least one characteristic of an optical fiber with the aid of a reflectometer, in which method the fiber to be characterized is connected at both ends to reference fibers and a reflectometer measurement is performed for each reference fiber. To determine if reflectometer data relating to the fiber to be characterized obtained after the two measurements is correct, reflectometer data corresponding to two equivalent points of the reference fibers is compared. The reflectometer data of the fiber to be characterized is retained only if the difference between the data compared is the same for both measurements. The reflectometer data compared for the two reference fibers consists of mean values for equivalent segments, for example.
