| Abstract: | The technological problems of the bidirectional hybrid fiber/coaxial(HFC) net in cable TV transmitting upwards are studied in detail. The concepts and causes of the special problems,such as collection interference and collection balance,in the passage of the net are described.Feasible plans are put forward to solve these problems that exist in the signals of the bidirectional HFC net,and security measures to strengthen upward transmission in cable TV are also discussed. |

| Keywords: | bidirectional HFC net upward transmission collection interference collection balance |
