2、pproved April 24, 2009American National Standards Institute, Inc.AbstractThis standard describes the point-to-point physical interface portions of Fibre Channel serial electrical andoptical link variants that support the higher level Fibre Channel protocols including FC-FS, HIPPI, IPI,SCSI and other

3、s. This standard is recommended for new implementations but does not obsolete existingFibre Channel standards.Approval of an American National Standard requires review by ANSI that therequirements for due process, consensus, and other criteria for approval havebeen met by the standards developer.Con

4、sensus is established when, in the judgement of the ANSI Board ofStandards Review, substantial agreement has been reached by directly andmaterially affected interests. Substantial agreement means much more thana simple majority, but not necessarily unanimity. Consensus requires that allviews and obj

5、ections be considered, and that a concerted effort be madetowards their resolution.The use of American National Standards is completely voluntary; theirexistence does not in any respect preclude anyone, whether he has approvedthe standards or not, from manufacturing, marketing, purchasing, or usingp

6、roducts, processes, or procedures not conforming to the standards.The American National Standards Institute does not develop standards andwill in no circumstances give an interpretation of any American NationalStandard. Moreover, no person shall have the right or authority to issue aninterpretation

7、of an American National Standard in the name of the AmericanNational Standards Institute. Requests for interpretations should beaddressed to the secretariat or sponsor whose name appears on the titlepage of this standard.CAUTION NOTICE: This American National Standard may be revised orwithdrawn at a

8、ny time. The procedures of the American National StandardsInstitute require that action be taken periodically to reaffirm, revise, orwithdraw this standard. Purchasers of American National Standards mayreceive current information on all standards by calling or writing the AmericanNational Standards

40、.1.8 average power: the optical power measured using an average-reading power meter when transmitting valid 8B/10B transmission characters.3.1.9 bandwidth: in FC-PI-4 context, the corner frequency of a low-pass transmission characteristic, such as that of an optical receiver.3.1.10 baud: a unit of s

41、ignaling speed, expressed as the maximum number of times per second the signal may change the state of the transmission line or other medium. (Units of baud are symbols/sec.)
