Information technology - Fibre distributed data interface (FDDI) - Part 4: Single-mode fibre physical layer medium dependent (SMF-PMD)


Do you need a multi-user copy?




The Fibre Distributed Data Interface (FDDI) is intended for use in a high-performance general purpose multistation network and is designed for efficient operation with a peak data rate of 100 megabits per second. It uses a token ring architecture. This part of ISO/IEC 9314 extends the basic FDDI by allowing both multimode and single-mode fibre (MMF and SMF respectively) as transmission media. The basic FDDI provides for hundreds of stations operating over an extent of many kilometers. The individual link lengths supported by the basic FDDI are limited to two (2) kilometers by the characteristics of the multimode fibre it specifies. This extension to the basic FDDI standard allows links to about 60 kilometers depending on cable plant characteristics, by making it possible to include single-mode fibre links in a standard FDDI network.
