Systems and methods for efficient upstream multicast in passive optical networks. An upstream multicast source communicates an upstream multicast packet to the network. Subsequent downstream packet management achieved through use of source filters prevents a reflected copy of the original upstream multicast packets from being received by the upstream multicast source.
