CATV, which originally called community antenna television is more commonly known as “cable TV” now. Since the early 1990s, CATV has taken on some new dimensions. In addition to bringing television programs to those millions of people throughout the world who are connected to a community antenna, CATV is becoming an increasingly popular way to interact with the World Wide Web and other new forms of multimedia information and entertainment services.
In order to full-fill the demand of bandwidth and make the large number of channels transmit through the optical fiber with high speeds, CATV transmission system continuous optimization. Many new network technology is gradually applied into it, including the The hybrid fiber coax (HFC) system.

What is The Hybrid Fiber Coax (HFC) System
Hybrid Fibre Coax (HFC), which incorporates both fiber optic transmission components and copper coaxial transmission components is a way of delivering video, voice telephony, data, and other interactive services over coaxial and fiber optic cables. Hybrid fiber coax (HFC) system is fast becoming a major transmission vehicle for interactive broadband access to the World Wide Web, CATV, and other multimedia applications. (Figure 2. )
Figure 2. Basic Elements of HFC system
As the advanced CATV transmission system, HFC system uses fiber optic cable for the headend and feeder distribution system and coax for the customers end connection. HFC is also called as the second generation of CATV systems. It offers high-speed backbone data interconnection lines (the fiber portion) to interconnect end user video and data equipment. In addition, HFC system provides high performance at low cost because they can be designed to match the asymmetrical bandwidth needs of most broadband distribution systems.
Advantages of HFC
CATV/HFC Network Application
AS the CATV/HFC network technology increasing, CATV/HFC is more widely applied in the data transmissions. There are some application examples, we can see the diagram (Figure 3~5) below, which can clearly describe some application of CATV/HFC network.
