Fiber distributed data interface (FDDI), which is an optical data communication standard used for long distance networks provides communication with fiber optic lines up to 200 kilometers at a speed of 100 megabit per second (Mbps).
It should be noted that relatively recently, a related copper specification, called Copper Distributed Data Interface (CDDI) has emerged to provide 100-Mbps service over copper. CDDI is the implementation of FDDI protocols over twisted-pair copper wire.
FDDI uses a dual-ring architecture with traffic on each ring flowing in opposite directions (calledcounter-rotating). The dual-rings consist of a primary and a secondary ring. During normal operation, the primary ring is used for data transmission, and the secondary ring remains idle and available for backup. The primary purpose of the dual rings, as will be discussed in detail later in this chapter, is to provide superior reliability and robustness. FDDI was later extended to FDDI-2 for long distance voice and multimedia 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

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.
