System for realizing wideband inserting in wireless Tv-set network

The system consists of HFC hub head end used as an interface between the RFC data access network and outside, TV set used as the terminal of cable TV network and user terminal. The system implements the data access function through receiving data signal from splitter by computer connected with it. The system also consists of converging light station connected with HFC data access network through RFC hub head end and also connected with IP MAN, duplex mixer whose numbers equals the numbers of access equipment; each duplex mixer is connected one to one with one of multi data access equipments, except connected with radio frequency amplifier; the duplex mixer mixes the CATV ratio frequency signal with data modulation radio signal, and de-mixes mixing radio frequency distribution network for making multi path distribution for the inputted radio frequency signal.
