Hybrid fiber coaxial network (HFC network) is a telecommunications technology that transmits broadband content such as video, data, and voice by mixing fiber and coaxial cables at different proportions. Hybrid fiber coaxial network (HFC network) is a telecommunications technology that transmits broadband content such as video, data, and voice by mixing fiber and coaxial cables at different proportions.
Using a hybrid fiber coaxial network, a local limited television (CATV) operator can connect to switching centers and commercial network nodes with fiber optics, as well as close individual users, using coaxial cables to connect small companies and other individual users. The advantage of this networking approach is that it can take advantage of the high bandwidth and low noise characteristics of fiber optics without replacing existing coaxial cables on the user side.
