In the 1980s, several token ring network implementations for LANs were developed.<ref>{{cite journal |title=Early Token Ring Work at MIT |author=J.

[[Fiber Distributed Data Interface]] (FDDI), a LAN standard, was considered an attractive campus [[backbone network]] technology in the early to mid 1990s since existing Ethernet networks only offered 10&nbsp;Mbit/s data rates and Token Ring networks only offered 4&nbsp;Mbit/s or 16&nbsp;Mbit/s rates. Thus it was a relatively high-speed choice of that era, with speeds such as 100&nbsp;Mbit/s.
By 1994, vendors included [[Cisco Systems]], [[National Semiconductor]], Network Peripherals, SysKonnect (acquired by [[Marvell Technology Group]]), and [[3Com]].<ref>{{Cite news |title= Wading Through Plethora of Options Poses Challenge for Life on the Fast LAN |work= Network World |pages= 41, 44, 46–49 |author= Mark Miller |date= March 21, 1994 |url= https://books.google.com/books?id=eA0EAAAAMBAJ&pg=PA47 |access-date= August 15, 2013 }}</ref> FDDI installations have largely been replaced by Ethernet deployments.<ref>{{Cite book |title= Optical Fiber Communication: Principles and Systems |pages= 241–249 |author=A.
