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.
10BASE-F, or sometimes 10BASE-FX, is a generic term for the family of 10 Mbit/s Ethernet standards using fiber-optic cable.In 10BASE-F, the 10 represents a maximum throughput of 10 Mbit/s, BASE indicates its use of baseband transmission, and F indicates that it relies on a medium of fiber-optic cable.
FDDI-style MMF An updated version of the FOIRL standard for end nodes, 2 km reach over FDDI-style multi-mode fiber, 850 nm wavelength 10BASE-FB: 802.3j-1993 (15&17) 2000 m Intended for backbones connecting a number of hubs or switches as a direct successor to FOIRL; deprecated 2011. [11] 10BASE‑FP: 802.3j-1993 (15&16) 1000 m
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 ...
The 100BASE-FX physical medium dependent (PMD) sublayer is defined by FDDI's PMD, [24] so 100BASE-FX is not compatible with 10BASE-FL, the 10 Mbit/s version over optical fiber. 100BASE-FX is still used for existing installation of multimode fiber where more speed is not required, like industrial automation plants.
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 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 ...
