标准摘要
[中文适用范围]： 该国际标准描述了基于 ISO/IEC 14165-115 并对其进行补充的光纤通道物理接口。 它指定了 ISO/IEC 7498-1 中定义的 1000BASE-TX2/4 PHY 层的介质相关接口以及对物理层和 MAC (TBI) 接口的影响。 规定了提供 10 或更低误码率所需的加扰、编码和调制。 本标准还规定了介质（传输通道）的要求。 这些要求在专用平衡 F 类通道的最低性能范围内（通常由最长 100 m F 类平衡（双绞线）布线组成，如 ISO/IEC 11801:2002 中规定）。 该国际标准支持信令速率为 1 062.5 Mbit/s 的全双工传输。 该国际标准提供了一个低复杂度的媒体独立接口和用于 100 MB/s 传输的以太网物理层的功能描述，许多供应商可以轻松实现。 该标准利用了 ISO/IEC 11801:2002 中规定的 F 类平衡布线通道所提供的改进的传输特性。 [外文原描述]： Fibre Channel provides a general data transport vehicle for Upper Level Protocols (ULPs) such as Intelligent Peripheral Interface (IPI) and Small Computer System Interface (SCSI) command sets, the High-Performance Parallel Interface (HIPPI) data framing, IP (Internet Protocol), ANSI/IEEE 802.2, and others. This part of ISO/IEC 14165, FC-100-DF-EL-S, specifies a Media Dependent Interface for duplex Ethernet transmission of 100 MB/s--a physical layer interface for a signalling rate of 1 062,5 Mbit/s over two pairs--for operation over Class F balanced cabling channels, for up to 100 m of Category 7 balanced (twisted pair) cabling. It includes a functional description of an Ethernet physical layer for 100 MB/s transmission of low complexity that can easily be implemented by many vendors. Taking advantage of the improved transmission characteristics provided by balanced cabling channels Class F as specified in ISO/IEC 11801 (2002), it eliminates the need for implementation of the complex functions specified in ISO/IEC 8802-3 that cancel the effects of crosstalk and return loss. This provides a solution that can operate at a much lower power level, and that can be implemented at a lower cost than products that use Clause 40 of ISO/IEC 8802-3. Therefore it also has the potential for multiple ports per chip.
