What does FDDI primarily utilize for network connections?

FDDI, or Fiber Distributed Data Interface, primarily utilizes fiber optics for network connections. This technology is designed to use optical fiber to transmit data, which significantly enhances the speed and distance capabilities of the network compared to traditional copper-based connections. Fiber optics allow for higher bandwidth and reduced signal attenuation, making them ideal for backbone networks or environments requiring high data transmission rates.

FDDI employs dual-ring architecture, which not only provides the main pathway for data but also offers redundancy, improving reliability in networking. This is particularly important as it allows data to be rerouted in case of a failure in one of the rings.

While other types of cabling, like coaxial and twisted-pair cables, exist and can be used in various network configurations, they do not match the performance standards set by FDDI utilizing fiber optics. Wireless technologies, while increasingly popular, operate on different principles and are not the foundation of FDDI network implementations. Overall, the use of fiber optics in FDDI enables faster, more reliable, and greater data carrying capacity than the alternatives mentioned.
