光纤通道为 上层协议（ULP），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的这一部分定义了支持光纤通道的结构的要求 独立于特定结构拓扑的物理和信令接口（FC-PH）。 FC-PH及其第二代（FC-PH-2）和第三代（FC-PH-3）描述了 a的点对点物理接口传输协议和信令协议 支持更高级别协议的高性能串行链路。

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 defines requirements for Fabrics supporting the Fibre Channel Physical and Signaling Interface (FC-PH) that are independent of specific Fabric topologies. FC-PH, together with its second generation (FC-PH-2) and third generation (FC-PH-3), describes the point-to-point physical interface transmission protocol and signaling protocol of a high-performance serial link for the support of higher level protocols.
