Which type of cable is typically used for high-speed data transmission?

Fiber optic cable is primarily utilized for high-speed data transmission due to its ability to carry data as light signals through thin strands of glass or plastic. This method of transmitting data allows for significantly higher bandwidth and faster speeds than traditional copper cables. Fiber optic cables are also less susceptible to electromagnetic interference, which can degrade signal quality in copper-based systems, making them an ideal choice for modern high-speed internet, telecommunications, and data networking applications.

The unique properties of fiber optic cables enable them to handle larger amounts of data over longer distances without the attenuation that can occur with other types of cables. This characteristic is essential for infrastructures that demand high-speed connections, such as those found in internet service providers and large organizations requiring robust data communication networks.
