Twinaxial cables are typically used for short-distance connections between switches and servers within the same data center. This is because they provide high-speed data transmission with low latency and low interference, which is ideal for environments requiring high bandwidth over short distances. Fiber optic cables, though capable of high-speed data transmission, are generally used for longer distances due to their ability to transmit data over kilometers without significant loss. Coaxial cables are more commonly used in broadband connections, like cable internet services, not within data centers for connecting switches and servers. UTP cables are used widely in local area networks but do not match the speed and shielding advantages of twinaxial cables for data center applications.
