Abstract: PURPOSE: An optical line terminal device for controlling power and an optical network end device are provided to include traffic monitoring units for monitoring uplink and downlink traffics of the optical line terminal. CONSTITUTION: A MAC(Media Access Control) block(120) converts port IDs and Ethernet packets into a downlink frame or converts an uplink frame into the port IDs and the Ethernet packets. A traffic monitoring unit(123) of the MAC block supplies ID information of an ONT(Optical Network Terminal) or an ONU(Optical Network Unit). A CPU(Central Processing Unit)(130) generates a control frame according to ID information.

Abstract: According to a method of reducing power in an optical access network, upon the application of power, an optical network terminal (ONT) operates normally in an activation mode. The ONT then determines whether the requirements for switching from activation mode to power-saving mode are satisfied. If the requirements are satisfied, the ONT transmits a sleep signal to an optical line terminal (OLT), which is a message notifying that the ONT will soon switch to power-saving mode. Thereafter, the ONT switches to power-saving mode and cuts off power for all functions except for power for monitoring and controlling external inputs. The ONT then determines whether the requirements for switching from power-saving mode to activation mode are satisfied. If the requirements are satisfied, the ONT transmits a wake-up signal to the OLT and switches to the activation mode for normal operation.
Abstract translation: 根据一种降低光接入网中的功率的方法，在通电时，光网络终端（ONT）以激活模式正常工作。 ONT然后确定是否满足从激活模式切换到省电模式的要求。 如果满足要求，则ONT将睡眠信号发送到光线路终端（OLT），该OLT是通知ONT将很快切换到省电模式的消息。 此后，ONT切换到省电模式并切断除监视和控制外部输入的电源以外的所有功能的电源。 ONT然后确定是否满足从省电模式切换到激活模式的要求。 如果满足要求，则ONT向OLT发送唤醒信号并切换到正常操作的激活模式。

Abstract: An automatic power control method for OLT(Optical Line Terminal) in PON(Point-To-Multipoint), and a storage media for performing the same are provided to operate an optical transmitter by selecting an optimal output level according to ODN(Optical Network Unit) structure of an associated PON(Passive Optical Network) and turns off the laser of the optical transmitter when all ONUs are non-operation state, thereby reducing unnecessary power consumption and manufacturing cost. An automatic optical output control method for OLT(Optical Line Terminal) in PON(Point-To-Multipoint) comprises the following steps of: measuring possible permission optical output ranges which can be normally performed on PON(101); selecting an optimal light signal level in the measured possible permission optical output ranges(103); and adjusting an output level of a transmitter by a pre-selected optimal light signal(104). The measuring step includes an ONU(Optical Network Unit) activating step, a step for confirming the number of activated ONU, and a power saving mode performing step.
