Abstract: To allow for the characterization of a passive optical network, reflectometry data is closely analyzed to determine reflection events within the data, and to subsequently characterize the reflection events so the status, operating parameters and efficiency of the network can be monitored. The reflectometry data is analyzed using statistical techniques to identify and analyze reflection events, which will ultimately allow meaningful reports to be generated which characterize the operation of the passive optical network. The reports can thus be provided to operators and/or installers to determine the health of the network, and whether any revisions are necessary.
