Abstract

The invention discloses a power adjustable passive optical fiber network system and a control method thereof. The power adjustable passive optical fiber network system comprises a central control station, an optical line terminal unit, an optical distribution network unit and an optical network unit, wherein the central control station is provided with a network manager, receives an alarm to trigger adjustment of power supply of a pump light source, and realizes output of different pump light power; the optical line terminal unit comprises OLT equipment, a first optical filter, an optical coupler, an optical isolator and the pumping light source; the optical distribution network unit comprises an erbium-doped optical fiber, a second optical filter and an optical splitter; and the optical network unit comprises a plurality of sets of ONU terminal equipment. The power adjustable passive optical fiber network system and the control method thereof solve the problem of insufficient opticalpower that occurs in the using process of a user ONU terminal.

Description

technical field [0001] The invention relates to a passive optical fiber network system and its control method, in particular to a passive optical fiber network system with adjustable power and its control method. 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] An optical splitter, also known as an optical splitter, is one of the ...
