信息技术 光纤分布式数据接口（FDDI） 第20部分：FDDI物理层相关媒体一致性试验用抽象测试套(FDDI PMD ATS)

[中文适用范围]： ISO/IEC 9314 的这一部分规定了一系列测试，以验证 FDDI 站是否符合 ISO/IEC 9314-3:1990 的要求。 注：ISO/IEC 9314-3 规定了 FDDI 站以及电缆设备的光输入/输出端口的要求。 它规定，对于通过合格电缆设备相互连接的合格站，站到站链路的误码率不应超过 2.5 × 10。 [外文原描述]： The Fibre Distributed Data Interface (FDDI), ISO/IEC 9314, 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 Mbit/s. It uses a Token Ring Architecture with optical fibre as the transmission medium. FDDI provides for hundreds of stations operating over an extent of tens of kilometres. The FDDI Physical Media Dependent (PMD) standard, ISO/IEC 9314-3, specifies the lower sublayer of the Physical Layer for the FDDI, including the optical interface for multimode fibre FDDI stations. This part of ISO/IEC 9314 is an abstract test suite (ATS) conformance test for FDDI PMD. ISO/IEC 9314-3 specifies the optical interface of FDDI stations; it is not a protocol standard and this part of ISO/IEC 9314 requires the measurement of physical quantities such as optical power, wavelength and signal jitter. The intent of this part of ISO/IEC 9314 is to specify the tests as broadly as possible to allow measurement by various detailed test implementations.
