Method for localizing an optical network termination in an optical access network

摘要

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.

1. A method for localizing an optical network termination in an optical access network, said optical access network comprising an optical line termination and a number of optical links, said optical network termination capable of being connected to said optical line termination by means of any of said optical links, comprising:
detecting that said optical network termination is connected to one of said optical links and retrieving therefrom a termination identifier univocally identifying said optical network termination; using said termination identifier for retrieving an optical link identifier associated with said termination identifier and univocally identifying a given optical link of said optical links; inducing a change in an optical connection between said optical line termination and said given optical link, thereby modifying an optical parameter of first optical signals received at said optical line termination through said given optical link; checking whether second optical signals received at said optical line termination from said optical network termination are affected by said change; in the affirmative, determining that said optical network termination is connected to said given optical link; and when not in the affirmative, determining that said optical network termination is not connected to said given optical link.
