What type of cable is primarily used for internet service installation?

Coaxial cable is primarily used for internet service installation, especially in cable internet systems. This type of cable consists of a central conductor surrounded by insulation, a metallic shield, and an outer cover, allowing for the transmission of data at high speeds over long distances. Coaxial cable is particularly effective for carrying television signals and internet data simultaneously, making it a popular choice among internet service providers.

While fiber optic cable is increasingly being deployed for high-speed internet due to its superior bandwidth capacity and faster speeds, coaxial remains the standard for many existing infrastructures, particularly in residential areas. Twisted pair cable and Ethernet cable are more commonly associated with local area networks (LANs) and internal wiring rather than the main conduit for internet service installation.
