In order to achieve high-speed and reliable transmission of integrated services in HFC networks, fusion channel technology has become the trend of HFC network development. This paper focuses on the key technologies of bidirectional transmission in HFC network fusion channel, including frequency domain equalization, hybrid mode, redundant protection and so on. Through theoretical analysis and simulation, the key technologies of HFC network fusion channel are explored and evaluated. The results of this study can provide some reference and guidance for the application of HFC network in fusion channel technology.【Keywords】HFC network, fusion channel, bidirectional transmission, frequency domain equalization, hybrid mode, redundant protection
