Abstract

The invention discloses an optical network unit terminal with adjustable power and a control method thereof. The optical network unit terminal comprises a central control station, an optical line terminal unit, an optical distribution network unit and an optical network unit. The central control station is provided with a network management to receive adjustment of an alarm triggering pump light source power supply and realize different pump light power outputs. The optical line termination unit comprises an OLT device, and one end of the OLT device is connected with a network management of acentral control station. The optical distribution network unit comprises a beam splitter, and one end of the beam splitter is connected with an OLT device through a backbone optical cable; The opticalnetwork unit (ONU) consists of several new ONU terminal equipments, each ONU terminal equipments consists of an optical filter, optical coupler, erbium doped fiber, pump light source and traditionalONU terminal equipments. The invention solves the problem of insufficient optical power in the use process of the PON network.

Description

technical field [0001] The invention relates to an optical network unit terminal and a control method thereof, in particular to an optical network unit terminal with adjustable power and a control method thereof. Background technique [0002] PON (Passive Optical Network) means (in the optical distribution network) that it does not contain any electronic devices and electronic power supplies. ODN is composed of passive devices such as optical splitters (Splitters) and does not require expensive active electronic equipment. A passive optical network includes an optical line terminal (OLT) installed in a central control station, and a batch of supporting optical network units (ONUs) installed in user premises. The optical distribution network (ODN) between the OLT and the ONU includes optical fibers and passive optical splitters or couplers. For a typical network structure diagram, see figure 2 . [0003] ONU (Optical Network Unit) is the user-side device of the GEPON (Gigab...
