标准摘要
[中文适用范围]： ISO/IEC 9314 的这一部分规定了光纤分布式数据接口 (FDDI) 的单模光纤物理层介质相关 (SMF-PMD) 要求。 FDDI 使用光纤波导作为传输介质，在计算机和外围设备之间提供高带宽（每秒 100 兆比特）的通用互连。 FDDI 可配置为支持大约每秒 80 兆位（10 兆字节）的持续传输速率。 FDDI 可能无法满足所有无缓冲高速设备的响应时间要求。 FDDI 在分布在数公里范围内的许多站点之间建立连接。 FDDI 的默认值是根据 1000 个物理连接和 200 公里的总光纤路径长度计算的（请参阅 MAC 标准 – ISO/IEC 9314-2 或 ISO/IEC 9314-8）。 [外文原描述]： 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.
