Which type of Internet service uses coaxial cables for transmission?

Cable internet service utilizes coaxial cables to transmit data. Coaxial cables are designed to carry high-frequency signals, which is ideal for the high-speed transmission required for internet access. The structure of coaxial cables, consisting of a central conductor surrounded by insulation and a metal shield, allows for effective resistance to interference and maintains signal integrity over longer distances.

In contrast, DSL (Digital Subscriber Line) uses existing telephone lines (twisted pair copper cabling) for internet service, which limits its speed and bandwidth compared to cable options. Fiber optic internet relies on strands of glass or plastic for data transmission, allowing for faster speeds and greater bandwidth capabilities, but it does not use coaxial cables at all. Satellite internet relies on satellites to deliver data, which inherently involves different technology and equipment entirely, such as dish antennas rather than coaxial connections.

Consequently, cable internet is distinct in that its infrastructure is specifically based on coaxial cables designed to carry broadband signals effectively to customers.
