Energy-saving method and device of optical network unit, optical network unit and storage medium

Abstract

The invention discloses an energy-saving method and device for an optical network unit, the optical network unit and a storage medium, and the method comprises the steps: obtaining the parameter information of a transmission interval in a data uplink transmission process of the optical network unit when accessing the transmission interval between two data packets, wherein the parameter informationof the sending interval comprises a starting moment, an ending moment and duration of the sending interval; when judging that the duration of the sending interval is greater than a preset time threshold, setting a sleep period according to the parameter information of the sending interval and a preset condition, wherein the starting time and the ending time of the dormancy period are not earlierthan the starting time of the sending interval and not later than the ending time of the sending interval; controlling an optical module of the optical network unit to stop emitting light in the sleeptime period; and controlling the optical module to recover normal light emission at the end of the sleep period. The power consumption of the optical network unit can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to an energy-saving method and device for an optical network unit, an optical network unit and a storage medium. Background technique [0002] In the architecture of a PON network (Passive Optical Network, passive optical network), an OLT (Optical Line Terminal, optical line terminal) is connected to multiple ONUs (Optical Network Unit, optical network unit) through an optical splitter. In the upstream data transmission, the ONU transmits in a burst state, and at the same time, only the ONU that has been assigned a time slot emits light upstream. [0003] At present, in the ONU time slot allocated by the current OLT, the ONU is always in a light-emitting state, thereby realizing uplink data transmission. However, in the process of implementing the present invention, the inventor found that currently in the data uplink transmission process of the optical networ...

Problems solved by technology

However, the inventor found in the process of implementing the present invention that at present, during the uplink data transmission process of the optical network unit, the uplink data packets of the optical network unit are all transmitted strictly according to the allocated time, between every two uplink data packets There is a certain sending interval, but the optical network unit still keeps lighting whether it is sending data packets or in the sending interval between data packets, resulting in a waste of energy
