Method and system for testing a fibre optic network

Abstract

Method and System for Testing a Fibre Optic Network A method (500) of testing a fibre optic network (100) so as to locate a feature of said network using a Mechanically Induced Filter (200), MIF, comprising a grating (210), the method comprising the steps of: retrieving, from an optical reflectometry measuring device (120), a: first test result (600-1), from a first optical reflectometry test performed through a fibre optic cable (170-1) of the fibre optic network, said first test result comprising a reflection result (610) indicative of a feature within the fibre optic network (510); second test result (600-2), from a second optical reflectometry test performed whilst using a MIF to force the grating upon the fibre optic cable, at a selected location, so as to cause a filtering effect upon the second test result (520); comparing the first test result and the second test result so as to identify whether the reflection result is affected in the second test result by the filtering effect (530); and determining, along the fibre optic cable, a location range for the feature, in which said location range is determined to be: away from both the optical reflectometry measuring device and the selected location, in response to identifying that the reflection result is affected by the filtering effect (540); and between the optical reflectometry measuring device and the selected location, in response to identifying that the reflection result is not affected by the filtering effect (550).
