本技术报告定义了光纤通道端口的物理（FC-0）层和传输协议（FC-1）层之间的高速并行接口的功能和电气特性。该接口在2125,0或1062,5 Mbaud下运行。与先前发布为X3的iFibre通道-10位接口相比，该接口具有额外的功能和不同的电气特性。TR-18:1997，仅在1062,5 MBaud下运行。本文件完全适用于dhe FC-0和FC-1层作为单独设备实现的系统。对于集成了FC-0和FC-1设备的系统，仅本文件的功能特征适用。

This technical report defines the functions and electrical characteristics of the high-speed parallel interface between the physical (FC-0) layer and the transmission protocol (FC-1) layer of a Fibre Channel port. This interface operates at either 2 125,0 or 1 062,5 Mbaud. This interface has additional functions and different electrical characteristics compared to the iFibre Channel - 10-bit Interfacei, previously published as X3.TR-18:1997, which operated at 1 062,5 MBaud only. This document applies in full to systems where dhe FC-0 and FC-1 layer are implemented as separate devices. For systems where the FC-0 and FC-1 devices are integrated, only the functional characteristics of this document apply.
