What does FDDI primarily use for networking?

FDDI, or Fiber Distributed Data Interface, primarily utilizes fiber optics for networking. This technology enables high-speed data transmission over long distances with minimal loss of signal quality, making it ideal for backbone connections within metropolitan area networks. Fiber optics can support higher bandwidths compared to copper cabling, which is crucial for maintaining performance in environments where large amounts of data need to be transmitted quickly and efficiently.

The use of fiber optics in FDDI allows for greater distances between devices without degradation of the signal, which is a significant advantage over other cabling options. Additionally, fiber optics provide enhanced security against eavesdropping and are less susceptible to electromagnetic interference. These characteristics make FDDI a robust choice for enterprise-level networking.
