Fiber Distributed Data Interface (FDDI) is a standard for data transmission in a local area network. It uses optical fiber as its standard underlying physical medium. It was also later specified to use copper cable, in which case it may be called CDDI (Copper Distributed Data Interface), standardized as TP-PMD (Twisted-Pair Physical Medium ...
FDDI was established under the aegis of the Ministry of Commerce and Industry, Government of India in 1986 with an objective to provide human resource and technical services to the industry. FDDI was upgraded to an Institute of National Importance by an act of parliament in 2017.

It is an improvement of an older standard (also created by ANSI) which used the Fiber distributed data interface (FDDI) network structure. The FDDI-based standard failed due to its expensive implementation and lack of compatibility with current LAN standards. The IEEE 802.6 standard uses the Distributed Queue Dual Bus (DQDB) network form. This ...
On legacy FDDI multimode fiber it can reach up to 300 m while on single-mode fiber it can reach up to 10 km. After these specifications have been laid out, they are then completed with local area network and wide area network specifications using different physical coding sublayer standards.

In the 802.3 standard, reference is made to FDDI-grade MMF fiber. This has a 62.5 μm core and a minimum modal bandwidth of 160 MHz·km at 850 nm. It was originally installed in the early 1990s for FDDI and 100BASE-FX networks. The 802.3 standard also references ISO/IEC 11801 which specifies optical MMF fiber types OM1, OM2, OM3 and OM4. OM1 ...
The Fiber Optic Technical Advisory Group was to create a LAN standard for fiber optic media used in token passing computer networks like FDDI. [1] This was part of the IEEE 802 group of standards. The group had given up and disbanded itself and is no longer a part of IEEE standards.
