Abstract
A method for localizing an optical network termination in an optical access network including an optical line termination and a number of optical links. The method includes: detecting that the optical network termination is connected to an optical link and retrieving from it a termination identifier univocally identifying the optical network termination, using the termination identifier for retrieving an optical link identifier associated with the termination identifier and univocally identifying a given optical link of the optical links; inducing a change in an optical connection between the optical line termination and the given optical link, thus modifying an optical parameter of first optical signals received at the optical line termination through the given optical link; checking whether second optical signals received at the optical line termination from the optical network termination are affected by the change; and in the affirmative, determining that the optical network termination is connected to the first optical link.
