ABSTRACT
In order to meet the demand of people for interactive television at this stage, cable television of area need to be established with two-way HFC network system. With the actual situation of the model community, planned the entire access network options, including two parts of the design as optical fiber access networks, coaxial cable distribution network, give out the design principles, design method, topology, equipment selection, parameters and so on to a detailed description. Finally research the HFC network uplink channel noise source, nature and uplink channel noise and interference solution.
