本美国国家标准规定了一种媒体级、点对点、12通道、全双工、电/光接口，每个通道以500 Mbit/s或1 Gbit/s的速度工作。多模（MM） 当承载HIPPI-6400-PH协议时，光缆和单模（SM）光缆可用于长达1公里的距离。差分信号用于电气侧。

This American National Standard specifies a media-level, point-to-point, 12-channel, full-duplex, electrical/optical interface, with each channel operating at 500 Mbit/s or 1 Gbit/s. Multimode (MM) fiber cables, and single-mode (SM) fiber cables, are used for distances up to 1 km when carrying the HIPPI-6400-PH protocol. Differential signals are used on the electrical side.
