Cable service primarily runs on which type of cables?

Cable service primarily runs on TV coaxial cables because these cables are specifically designed to carry a broad range of frequencies, including the radio frequency signals used for cable television. Coaxial cables have a central conductor that transmits the data, surrounded by insulation and metallic shielding, which helps to reduce interference and maintain signal quality over long distances. This design allows cable providers to deliver multiple channels and high-speed internet through the same infrastructure.

In contrast, telephone wires are mainly used for voice transmission and are not suitable for large quantities of data like cable service. Optical fiber cables, while providing superior speed and bandwidth, are typically used for internet and telephone services rather than traditional cable television. Ethernet cables are primarily utilized for local area networks (LANs) and connecting devices within a building, not for delivering cable service to homes. Therefore, the choice of TV coaxial cables as the primary medium for cable service is based on their effectiveness in delivering a stable and high-quality signal for television broadcasts and internet access.
