Which type of cable is primarily used for high-speed internet connections?

Fiber optic cables are primarily used for high-speed internet connections due to their ability to transmit data at much higher speeds and over longer distances than other types of cables. They use light to transmit information, which enables them to achieve bandwidths of several hundred Gbps, making them ideal for modern internet infrastructure and high-demand applications such as streaming and online gaming.

Moreover, fiber optic technology is less susceptible to interference compared to copper cables, which enhances reliability in data transmission. This quality makes fiber optic cables a preferred choice for ISPs (Internet Service Providers) when laying down the groundwork for new high-speed networks, enabling users to enjoy faster and more stable internet connections.

Coaxial cables are often used for cable television and some high-speed internet services but do not match the speed capabilities of fiber optics. Cat 5e Ethernet cables are suitable for local networks and can support speeds up to 1 Gbps over limited distances but fall short in comparison to fiber's performance. HDMI cables are primarily designed for transmitting high-definition video and audio between devices and are not used for internet connections.
