Abstract
An optical access network employs a ring topology in which connections between the network units and between the network units and the optical line terminal are via a protection switch. The protection switch monitors connections from the optical network units to detect a loss of signal and, on detecting a loss of signal from an optical network unit, switches the respective optical network unit out of the ring, thus maintaining continuity of the ring topology.
