本标准描述了链路服务要求。描述了物理接口要求 在光纤通道物理接口-2（FC-PI-2）中。框架和信号要求如下: 光纤通道物理帧和信令-2（FC-FS-2）中描述。建议使用本标准 适用于新的实施，但不会过时现有的光纤通道标准。

This standard describes the Link Services requirements. The Physical Interface requirements are described in Fibre Channel-Physical Interfaces - 2 (FC-PI-2). The Framing and Signaling requirements are described in Fibre Channel-Physical Framing and Signaling - 2 (FC-FS-2). This standard is recommended for new implementations but does not obsolete the existing Fibre Channel standards.
