What technology does FDDI rely on mostly?

The technology that FDDI (Fiber Distributed Data Interface) predominantly relies on is fiber optic cabling. This choice is correct because FDDI is designed to utilize optical fibers to achieve high-speed data transmission over local area networks. Fiber optic cabling allows for greater bandwidth and data transfer rates compared to other media, making FDDI capable of supporting data rates up to 100 Mbps.

This technology also minimizes signal degradation over long distances and is less susceptible to electromagnetic interference, which is a significant advantage in network design. FDDI typically uses a dual-ring topology, enhancing redundancy and reliability in network connections. The use of fiber optics is fundamental to the FDDI standard, distinguishing it from other networking technologies that may utilize different forms of cabling, such as coaxial cables or twisted pair wiring.
