    Abstract: System and method for providing fast protection in a passive optical network (“PON”) including two central hubs and a plurality of network nodes, wherein the network nodes are connected to a first of the central hubs by a first optical path and to a second of the central hubs by a second optical path. The method comprises setting the first and second central hubs to master mode and slave mode, respectively, such that only the first central hub transmits traffic to and from the network nodes; detecting a failure in the first optical path; exchanging status information between the first and second central hubs; and if no failure has occurred in the second optical path, setting the first and second central hubs to slave mode and master mode, respectively, such that only the second central hub transmits traffic to and from the network nodes.
