光纤通道为上层协议（ULP）提供了通用数据传输工具，如智能外围接口（IPI）和小型计算机系统接口（SCSI）命令集、高性能并行接口（HIPPI）数据帧、IP（互联网协议）、ANSI/IEEE 802.2等。ISO/IEC 14165 FC-100-DF-EL-S的这一部分规定了100 MB/S双工以太网传输的媒体相关接口——两对上1062,5 Mbit/S信令速率的物理层接口——用于F级平衡布线信道上的操作，用于高达100 m的7类平衡（双绞线）布线。它包括以太网物理层的功能描述，用于100 MB/s的低复杂度传输，可由许多供应商轻松实现。利用ISO/IEC 11801（2002）中规定的F类平衡布线信道提供的改进传输特性，无需实现ISO/IEC 8802中规定的复杂功能- 3消除串扰和回波损耗的影响。这提供了一种解决方案，可以在更低的功率水平下运行，并且与使用ISO/IEC 8802-3第40条的产品相比，可以以更低的成本实施。因此，它也有可能为每个芯片提供多个端口。

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.
