Abstract
An Optical Line Terminal (OLT) system configured to operate in a Passive Optical Network (PON) includes a transmitter configured to communicate with a plurality of Optical Network Units (ONUs) on a downstream channel that is shared by all of the plurality of ONUs; and one or more receivers configured to communicate with the plurality of ONUs on an upstream channel and on an out-of-band channel, wherein the upstream channel is Time Division Multiple Access (TDMA) such that one of the plurality of ONUs transmits at a time. Also, the OLT system can include circuitry configured to cache characteristics of the plurality of ONUs for configuring the receiver.
