Abstract:

A method for a first optical transceiver to range one of a plurality of second optical transceivers. The method my include broadcasting a first ranging grant, determining whether a runt response is received in a quiet window, changing one of the desired delay or a timing of the quiet window in response to determining that no runt response was received, repeating the broadcasting and the determining in response to determining that no runt response was received, identifying one of the unranged second optical transceivers in response to determining that a runt response was received, and establishing a ranged state with the identified unranged second optical transceiver. The first ranging grant including a delay request indicating a first delay before unranged second optical receivers respond. The quiet window is a time when no responses are expected from the second optical transceivers.

Abstract:

A method of handling upstream data transmissions in a passive optical network includes determining signal power levels of a plurality of optical network units (ONUs); and scheduling transmissions of upstream data bursts of the plurality of ONUs by, assigning each of the upstream data bursts to one of two or more data burst groups based on the determined signal power levels, and selecting time intervals during which the upstream data bursts are transmitted in accordance with the two or more data burst groups such that the two or more data burst groups are scheduled to be transmitted sequentially.
