What isFiber Distributed Data Interface

Fiber Distributed Data Interface (FDDI) is a high-speed network that is based on optical transmissions. It is designed for connecting high-end computers and workstations that require high-speed transmission of large amounts of data. The technology transport data at speeds of 100 megabits per second and supports up to 500 stations on a single network.

How Does FDDI Work?

FDDI uses fiber-optic cables that carry pulses of light to transmit information between stations. However, it can also operate on copper lines with electrical signals. An FDDI network can include up to 500 stations connected in a physical ring, with the transmitter port of one station generating a light signal that is transmitted over the fiber to the receiver port of the next station. The stations are interconnected in a star configuration using a concentrator.

Applications of FDDI

FDDI is commonly used as a network backbone to connect high-end computers such as mainframes and peripherals. It is also used for local area networks connecting powerful technical, graphics, and other workstations that require high-speed transmission of large amounts of data. FDDI is relatively expensive to implement due to the use of fiber optic cables, but the combination of fiber and copper cables can keep costs down.

FDDI vs. Ethernet and Token Ring

An operating system uses FDDI in the same way as 802.3 Ethernet or 802.5 Token Ring. The key difference is that FDDI uses fiber optic cables for transmission, while Ethernet and Token Ring use copper cables. This makes FDDI faster and more reliable over long distances, but also more expensive to implement.

Conclusion

FDDI is a high-speed network based on optical transmissions. It is designed for connecting high-end computers and workstations that require high-speed transmission of large amounts of data. FDDI uses fiber optic cables for transmission and can support up to 500 stations on a single network. Although FDDI is relatively expensive to implement, it provides faster and more reliable transmission compared to copper-based networks.
