Abstract
Official abstract text for this publication.
An optical communication system connects a plurality of user-side optical line terminating apparatuses (hereinafter referred to as ONUs) to a station-side optical line terminating apparatus (hereinafter referred to as OLT) using a common optical fiber. At least a part of the ONUs includes a transceiver having a power saving function for inactivating a transmitting unit while supplying electric power to a receiving unit and a control apparatus that transmits support information of the power saving function to the OLT via the transceiver, and the OLT includes a control apparatus that generates transmission allowance information of upstream communication based on the support information of the power saving function and a transceiver that receives the support information of the power saving function and transmits the transmission allowance information to the ONU.
First claim
Opening claim text (preview).
The invention claimed is: 1. A communication system that connects a plurality of user-side optical line terminating apparatuses (Optical Network Units, hereinafter referred to as ONUs) to a station-side optical line terminating apparatus (Optical Line Terminal, hereinafter referred to as OLT) using a common optical fiber, wherein the ONUs each includes: an optical transceiver connected to the optical fiber, with the optical transceiver being configured to reduce power consumption…
