Abstract
A communication system comprises a passive optical network (PON) having an optical line terminal (OLT) coupled to a plurality of optical network terminals (ONTs) through a power splitter. Each ONT is coupled to the power splitter via a subscriber line. A switch is coupled to each subscriber line, and all of the switches are coupled to a control element. A power element is configured to receive optical signals communicated by the PON and to convert the optical signals into electrical power for use by the control element. The OLT is configured to detect a rogue ONT and to communicate with the control element for opening the switch that is coupled to the subscriber line of the rogue ONT, thereby optically isolating the rogue ONT from the rest of the PON.
