FDDI Connector Hot Selling Model
FDDI was considered an attractive campus backbone network technology in the early to mid 1990s since existing Ethernet networks only offered 10 Mbit/s data rates and Token Ring networks only offered 4 Mbit/s or 16 Mbit/s rates. Thus it was a relatively high-speed choice of that era, with speeds such as 100 Mbit/s. By 1994, vendors included Cisco Systems, National Semiconductor, Network P. OverviewFiber Distributed Data Interface (FDDI) is a standard for in a. It uses as its standard underlying physical medium. It was also later specified to use cable, in w. FDDI provides a 100 optical standard for in that can extend in length up to 200 kilometers (120 mi). Although FDDI logical topology is a ring-based token network, it did not use.
