A new method for monitoring metro/access optical networks with complex hybrid topologies based on a tunable OTDR and reference reflections produced by reflective elements located in the network. Using a particular configuration for a ring + tree network, the system is able to maintain surveillance of the channels characteristic, to detect the presence of any intrusion in our optical link and to locate failures in the physical links.
