Fiber Distributed Data Interface (FDDI) NICs are commonly used to connect host systems or file servers to FDDI network equipment using one connectin (single attachment) and to attach the network equipment to the FDDI cabling through two attachments (dual attachment).
FDDI is defined by the ANSI X3T9.5 standards committee and provides an access method to enable high-capacity data throughput on busy networks. It has a data throughput rate of 100Mbps, and is simliar to the token ring access method because it uses token passing for network communication.
FDDI 1 vs FDDI 2Fiber Distributed Data Interface (FDDI) is a data transmission standard for Local Area Networks (LAN) which uses fiber optic lines. A FDDI LAN can extend up to 200 kilometers and it can support thousands of users. The FDDI 1 protocol is based on the token ring protocol. FDDI 2 is an extended version of FDDI. It extends FDDI by adding capability to handle voice and video signals.Difference between FDDI 1 and FDDI 2 (FDDI ii)FDDI-2 is the second generation protocol of FDDI. The key difference between them is that, in addition to all the functionality FDDI provides, FDDI-2 provides the ability to handle voice signals and video. Even though both FDDI and FDDI-2 runs at 100 Mbits/sec on the fiber and transport asynchronous and synchronous types of frames, FDDI-2 can transport isochronous traffic using the newly developed hybrid mode. Further, FDDI and FDDI-2 stations can be operated in the same ring only in the basic FDDI mode
Typically FDDI runs at 100 Mbps
WANs can use FDDI networks
FDDI networks can be up to 124 miles (200 kilometers) in length
That is fiber optic cable, as FDDI stands for Fiber Distributed Data Interface
FDDI refers to Fiber Disturbed Data Interface. Most people will just say FDDI for short. Most hoping, that the person in conversation knows what it stands for.
Ring network
Both Token Ring and FDDI use the concept of a ring topology structure. However, Token Ring is used in a LAN, and FDDI is used in a MAN.Token Ring is implemented with copper cable (UTP cable) and FDDI uses Fiber Optic cable.Finally, the protocols are very different between the two. FDDI uses a synchronous type of transmission, where Token Ring uses an actual token (a 3 character packet) to control who has access to transmit or receive on the network. FDDI does not use this technique.
The acronym FDDI stands for Fiber Distributed Data Interface, which provides enhanced data transmission in a local area network.
token passing
Fddi can be further connected to other networks whereas token ring is individual network of computers.
