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.

Methodology for efficient upstream multicast in PON networks

One embodiment of the present invention illustrates a high-speed PON converter ('HPC') configured to be a pluggable high-speed PON conversion device used for coupling a user equipment ('UE') to an optical network. HPC, in embodiment, includes a passive optical network (&#x201c;PON&#x201d;) interface, a high-speed electrical (&#x201c;HSE&#x201d;) interface, and a conversion component. The PON interface, which is coupled to an optical network via an optical fiber, is able to receive optical information from the optical fiber. The HSE interface is configured to be pluggable to the UE, such as a personal computer (&#x201c;PC&#x201d;), laptop, or tablet via a predefined removable connector. The conversion component converts and transmits signals between the HSE and PON interfaces.
