A high-speed (100Mb/s) LAN standard. The underlying medium is fibre optics, and the topology is a dual-attached, counter- rotating token ring. See also: Local Area Network, token ring. [Source: RFC1208

A method used to send data over an optical fibre network. This type of network supports data transfer rates in the order of 200 Mbps. This is more efficient at transferring data across a network than Ethernet networks (as the header used is smaller), and therefore allows greater amounts of data to be sent in the packets. See Ethernet and Packet.

A 100Mb/s LAN standard. The underlying medium is fibre optics, and the topology is a dual-attached, counter- rotating token ring. Fibre Optic Cable. This is the solution to the Backbone, and it is also, quite literally, a tunnel of light. Fiber Optic Cable is formed of a very fine strand of very pure glass. Signals are transmitted as pulses of light rather than as electrical current. There has to be a device at the end of the cable that translates these signals into the electrical current used by computers. However, the higher level structure of digital data is identical. It is still Bits (now represented by light pulses) strung together to form bytes, characters, data Packets, headers, etc. Fiber provides higher quality data transmission over longer distances with less chance of interference than copper wire.
