FDDI is a dual-ring structure, usually found in MANs (metropolitan area networks). Although it has a physical ring structure it is not the same as a token ring network.

Which network is FDDI?
Ring network
How is a FDDI network like a Token Ring network How is it different?
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.
What is difference between fddi and 802.5 token ring?
Fddi can be further connected to other networks whereas token ring is individual network of computers.
What is the transmission speed of token ring and FDDI?
16mbps
What is the difference between fddi-i and fddi-ii?
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
What are the advantages of FDDI over token ring?
Although they both use a rotating ring setup, the FDDI uses two to achieve better results and less chance of failure. FDDI also uses a timed protocol that leads to differences in frame format and how station traffic is controlled.
What is the logical topology used for ethernet architecture?
Topology: physical ring of trees, logical ring
Which network architecture can automatically correct for cable failures?
Token Ring and FDDI networks can.
Advantages and disadvantages of the Fiber Distributed Data Interface FDDI?
FDDI Advantages: ~Supports real time allocation of network bandwidth. ~Supports a lot of different types of network traffic. ~Is fault-tolerant because it uses dual fiber cables. If one cable fails FDDI moves the data to the other dual cable. FDDI Disadvantages: ~It's expensive ~There is always a chance of multiple ring failures and as the ring grows, that chance increases. ~It's not used frequently due to cost, companies prefer to use copper (CDDI) if they are taking the ring approach.
Which technologies use token passing method and a physical star but logical ring topology?
token ring uses a physical star and a logical ring ,while FDDI uses a physical star/ring and a logical ring.
What type of Physical layer is required for FDDI?
Uses a dual ring of single-mode or multimode fiber-optic.
What uses a double ring of multimode or single-mode fiber to transmit data at speeds of 100 Mbps?
FDDI
