At present, the radio and television network is facing the change of digital television. With the continuous development of network technology, the advent of new services has promoted the change of business and the continuous improvement of radio and television network technologies. At the same time, it has brought new market opportunities and development possibilities, So that the operation of radio and television network is facing new opportunities and challenges. By using EPON technology to build a two-way network, fiber-to-the-home can be realized and the informationization process of the entire people can be greatly accelerated. The author briefly introduces the concept and history of EPON, and discusses the key technologies of EPON from the aspects of the basic theory and standardization, the key technology points of EPON and the research and development of its devices. Finally, the application of EPON technology in CATV .
