Abstract

The invention discloses a passive optical network and a low-power-consumption control method thereof and an optical network unit. The low-power-consumption control method comprises the following steps that: an OLT (Optical Line Terminator) determines to send a low-power-consumption instruction to the ONU according to a preestablished strategy after an ONU (optical netunit) enters a low-power-consumption mode; and after receiving the low-power-consumption instruction, ONU system equipment of the ONU controls an ONU optical module of the ONU to enter the low-power-consumption mode. Because the OLT indicates to the ONU to enter the low-power-consumption mode according to the preestablished strategy, the OLT can master the situation of the ONU in the whole passive optical network and avoids confusion; and after the ONU optical module enters the low-power-consumption mode, the purposes of saving power consumption and saving energy sources can be achieved.

Description

technical field [0001] The invention relates to optical fiber communication technology, in particular to a passive optical network, its low power consumption control method and an optical network unit. Background technique [0002] In the current domestic market and international market, the optical fiber communication direction of high bandwidth, high speed and multi-service integration has begun to be applied; among many solutions, the emergence of fiber-to-the-home (FTTH) is considered to be the ultimate broadband access solution. The domestic market has been widely used. [0003] Among many FTTH solutions, GPON (Gigabit Passive Optical Network) has a maximum transmission rate of 2.5Gbps and supports multiple services, including ATM, Ethernet, TDM, and CATV. It can be said that it is the most functional solution at present. Perfect PON network technology is also a very economical and broadband-oriented network access method. Therefore, GPON network has attracted much at...
