Which cable type is known for being used in high-speed data transmission over long distances?

Fiber-optic cables are recognized for their superior ability to transmit data at high speeds over long distances. This type of cable works by using light to transmit data, which allows for greater bandwidth and less signal degradation compared to other types of cables. The core of a fiber-optic cable, typically made of glass or plastic, carries the light signals, and because light can travel much faster and more efficiently than electrical signals, fiber-optic cables can support very high data rates.

Furthermore, fiber-optic cables are less susceptible to electromagnetic interference, which can be a significant issue for other cable types like coaxial and twisted pair. This makes fiber-optic cables the preferred choice for long-distance telecommunications and internet backbones, as they can maintain signal integrity over large distances without the need for frequent signal boosters.

In summary, fiber-optic technology is pivotal in modern networking, making it the best option for high-speed data transmission over extensive distances.
