Charter Communications offers broadband Internet, TV, and phone service to consumers via their hybrid fiber coaxial (HFC) network.
Hybrid Fiber Coaxial is a broadband infrastructure that uses fiber optic cables as it’s backbone, only resorting to slower coaxial cables for the “last mile” between customer residences and a local “optical node.”
The optical node translates optic signals into electric signals, which are generally distributed via existing cable TV networks. A node may serve anywhere from 50-2,000 homes in an area.
This type of connection is widely called a “cable” internet connection due to the use of coaxial cable, which was historically used to offer “cable TV.”
