21、, (HIPPI-Serial) specifies a physical-level interface for transmitting digital data at800 Mbit/s or 1600 Mbit/s serially over fiber-optic cables across distancesof up to 10 km.

22、ces.HIPPI-Serial may be integrated as a hosts native interface, or used as anexternal extender for HIPPI-PH ports.This standard is based on the Serial-HIPPI Specification developed in anad hoc committee during 1990 through 1993. The ad hoc committeeincluded representatives from computer system manuf
23、acturers, peripheraldevice manufacturers, defense/aerospace equipment manufacturers, com-munications equipment manufacturers, users of data-processing systems,including National Laboratories and government agencies, as well as oth-ers who expressed an interest in developing such a specification. The
24、serepresentatives collectively possessed a considerable knowledge concern-ing computer interfacing in general, and the HIPPI standards in particular. Devices conforming to the Serial-HIPPI Specification are now available inthe commercial marketplace, and a desire to more formally document thespecifi
25、cation led to creating this standard. This standard includesenhancements beyond the Serial-HIPPI Specification, e.g., for short-wave-length optics, integrated native host interfaces, and clarifications to sometext.This document includes five annexes which are informative and are notconsidered part o

They should be sent to the NationalCommittee for Information Technology Standards (NCITS), ITI, 1250 EyeStreet, NW, Suite 200, Washington, DC 20005.This standard was processed and approv
27、ed for submittal to ANSI byNCITS. Committee approval of the standard does not necessarily implythat all committee members voted for approval.
