The traditional power line carrier communication (PLC) is developing towards the direction of large capacity and high speed, and at the same time it turns to adopt the low-voltage distribution network for carrier communication, laying the fiber composite low-voltage cable along the low-voltage power line, realizing the low-voltage power communication will become the future development trend.

Due to its advantages of high integration and resource saving in low-voltage communication access network, power optical fiber to the home has become the preferred technology to support smart power grid and revitalize power communication.Power fiber into the home is one of the signature technologies of smart power grid. It is a new power communication means proposed by state grid for strong smart power grid, realizing smart power grid function, and carrying out "three networks integration" business of telecommunication network, broadcasting network and Internet content transmission.Fiber optic communication has become an irresistible trend for its high speed stability and reliability, dry stability and reliability, and strong anti-interference ability.At present, the cost of optical fiber is very low, and the fiber composite low-voltage cable can greatly reduce the cost and avoid the waste of resources caused by the secondary construction.

As one of the effective ways to support smart power grid, power fiber to the home can optimize the energy structure, ensure the safe supply of energy, improve the power grid's ability to optimize the allocation of resources, and enhance the clean energy acceptance ability of the power grid system.Develop low-carbon economy, promote green energy access, adjust energy structure and promote smart city construction;To promote economic development, create a harmonious and beautiful life, and with the progress of science and technology and the change of social electricity demand, the development of smart homes, smart buildings, smart communities, smart cities, integrated information services and other business expansion.
