Research on PFTTH technology and four-network fusion technology

PFTTH(power fiber to the home) has become an urgent demand for the development of smart power grid.In order to achieve the goal of safe and reliable power consumption and whole-process optical fiber data transmission for the community users.In this paper, the concept, characteristics and functions of two key technologies of fiber optic composite low-voltage cable and passive optical network in PFTTH project are analyzed in detail,and the method of PFTTH engineering networking is obtained.The network architecture and networking design principles of the PFTTH in the smart power residential community were established, and the fiber-optic composite low-voltage cable home network configuration scheme based on the Ethernet passive optical network was developed and put into application. In the process of implementation, the content of network structure design of power fiber project in smart power residential area is clarified, Node configuration and the configuration of the three-network fusion and power information acquisition equipment are clarified, at the same time, the configuration of fiber cable and the way of fiber connection are described. The results show that the network structure of the power fiber optic-fiber project in the smart community is reasonable, safe and stable, which lays a foundation for promoting the construction of smart power grid.
