2、r 10, 2007 American National Standards Institute, Inc.AbstractThis standard describes extensions to the Fibre Channel signaling and physical layer requirements de-fined in ANSI INCITS 404-2005, Information Technology - Fibre Channel - Physical Interfaces 2, to trans-port Fibre Channel over the commo
3、nly available 4-pair balanced copper cablings specified in ISO/IEC11801:2002 and TIA/EIA-568-B.2-2001. This standard is one of the Fibre Channel family of standards.Approval of an American National Standard requires review by ANSI that therequirements for due process, consensus, and other criteria f
4、or approval havebeen met by the standards developer.Consensus 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 necessar
5、ily unanimity. Consensus requires that allviews and objections 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 no
6、t, from manufacturing, marketing, purchasing, or usingproducts, 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
7、 have the right or authority to issue aninterpretation 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 Ame
8、rican National Standard may be revised orwithdrawn at any 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 standard
