Abstract
Official abstract text for this publication.
In a PON system, an ONU includes a receive buffer that stores therein a signal in a downstream direction transmitted from an OLT and a PON control unit that controls transition to a power-saving state and transition to a normal state for the reception buffer. The OLT includes a transmission buffer that stores transmission data to be transmitted to the ONU and the PON control unit that transmits the downstream power-saving-state transition request that requests the ONU to transition to the downstream power-saving state when it is determined that transmission data addressed to the ONU is not present in the transmission buffer. The PON control unit sets the reception buffer to a power-saving state for a predetermined downstream sleep time requested based on the downstream power-saving-state transition request.
First claim
Opening claim text (preview).
The invention claimed is: 1. A passive optical network (PON) system in which a station-side terminal apparatus and a subscriber-side terminal apparatus are connected by using an optical line, wherein: the subscriber-side terminal apparatus includes: an optical transmitter that transmits an optical signal to the station-side terminal apparatus, and an upstream-data processor that performs processing on upstream data that is to be transmitted to the station-side terminal apparatu…
