Fiber Distributed Data Interface is a standard for data transmission in a local area network. It uses optical fiber as its standard underlying physical medium.

Ethernet is a family of wired computer networking standards designed for local area networks, access networks, and metropolitan area networks. It was commercially introduced in 1980 and first standard

…single ring can extend the maximum distance; a dual ring can extend 100 km (62 mi). FDDI had a larger maximum frame size (4,352 bytes) than the standard Ethernet family, which only supports a maximum frame size of 1,500 bytes, allowing better effective data rates in some cases. Designers normally constructed…
First pages of Xerox PARC memo authored by Metcalfe in 1973 establishing the basic principles of Ethernet.
Accton Etherpocket-SP parallel port Ethernet adapter (c. 1990). Supports both coaxial (10BASE2) and twisted pair (10BASE-T) cables. Power is drawn from a PS/2 port passthrough cable.

Older Ethernet equipment. Clockwise from top-left: An Ethernet transceiver with an in-line 10BASE2 adapter, a similar model transceiver with a 10BASE5 adapter, an AUI cable, a different style of transceiver with 10BASE2 BNC T-connector, two 10BASE5 end fittings (N connectors), an orange vampire tap installation tool (which includes a specialized drill bit at one end and a socket wrench at the other), and an early model 10BASE5 transceiver (h4000) manufactured by DEC. The short length of yellow 10BASE5 cable has one end fitted with an N connector and the other end prepared to have an N connector shell installed; the half-black, half-grey rectangular object through which the cable passes is an installed vampire tap.
