Abstract

The invention provides a multistage light-splitting structure system based on TWDM-PON and wireless signal fusion. The multistage light-splitting structure system comprises a local side, a first stage far-end node, a second stage far-end node, an optical network unit, an RRU / CELL module and distributed fibers, wherein the local side, the first stage far-end node, the second stage far-end node and the optical network unit are sequentially connected through the distributed fibers, and the RRU / CELL module is connected with the first stage far-end node through the distributed fiber. By utilizing the feature that the power budget of each hierarchical node in a passive optical network transmission system is different, the multistage light-splitting structure system provides power to the terminal units with different power budget demands, that is, the optical network unit and the RRU / CELL module, thereby meeting the power budget demands of different terminals appropriately and saving the energy consumption, and reducing total power demand of the circuit; and meanwhile, at the time the power budget demands of the terminals are met, the system is green and energy saving, and the line power burden is reduced.

Description

technical field [0001] The present invention relates to the technical field of optical communication, in particular to a multi-stage optical splitting structure system based on fusion of TWDM-PON and wireless signals. Background technique [0002] As user demands for high-speed, high-quality services such as high-definition television, interactive games, video conferencing, P2P transmission, and sensor IoT increase, the demand for access network bandwidth grows rapidly, and FTTx has become a hot spot for construction. Optical fiber access and wireless access have their own advantages. The advantages of optical fiber include low loss, high bandwidth, and anti-electromagnetic interference, while wireless access does not require cables. Access has a high degree of freedom anytime, anywhere, and can bring users To access services more conveniently and quickly. In addition, the characteristic that the optical fiber is not easy to be bent at will leads to high cost when laying in...
