What type of network cable is used for broadband cable Internet connections?

Coaxial cable is the correct choice for broadband cable Internet connections because it is specifically designed to carry high-frequency signals, which makes it ideal for transmitting cable television and data signals over long distances with minimal interference. This type of cable consists of a central conductor, an insulating layer, a metallic shield, and an outer insulating layer, allowing for effective signal transmission while protecting against external noise and interference.

When used in broadband applications, coaxial cable provides high bandwidth capacity necessary for delivering fast Internet speeds. It can support various services, including digital television and Internet, simultaneously through a single cable infrastructure. This versatility and reliability underlie its widespread use in home and commercial networking solutions associated with cable Internet services.

Other types of cables, while useful in different contexts, don’t serve the specific purpose of broadband cable Internet connectivity as effectively. For instance, fiber optic cables utilize light to transmit data and can provide very high speeds over longer distances, often used in backbone connections rather than standard home use. Twisted pair cables, though commonly used in local area networks (LANs), lack the bandwidth and shielding capabilities of coaxial cables for broadband Internet services. HDMI cables are fundamentally designed for transmitting high-quality audio and video signals between devices and are not used for Internet connectivity
