Abstract
A method for localizing an optical network termination (ONT) of a passive optical network is disclosed. The passive optical network comprises an optical line terminal (OLT) and an optical distribution network (ODN) having a plurality of optical links. The ONT is connectable to the OLT by a given optical link of the optical distribution network. The method includes the steps of detecting that the ONT has been connected to the OLT by an optical link of the optical distribution network; determining length information indicative of a length of the optical link; comparing the length information with a reference length information indicative of a length of the given optical link; and if the length information matches the reference length information, localizing the ONT by confirming that it is connected to the OLT by the given optical link.
