Describes Physical Layer, Medium Dependent requirements for the Fibre Distributed Data Interface. Provides a high-bandwith (100 Mbit/s) general-purpose interconnection among computers and peripheral equipment using fibre optics as the transmission medium. May be configured to support a sustained transfer rate of approximately 80 Mbit/s. May not meet the requirements of all unbuffered high-speed devices. It establishes the connection among many nodes distributed over distances of several kilometers. Default values were calculated on the basis of 1000 physical connections and a total fibre path length of 200 km. BS AMD 9267 RENUMBERS THIS STANDARD
