2、lApproved January 28, 2015American National Standards Institute, Inc.AbstractThis standard describes the point-to-point physical interface portions of Fibre Channel serial electricaland optical link variants that support the higher level Fibre Channel protocols. This standard is recom-mended for new
3、 implementations but does not obsolete existing Fibre 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.Consensus is established when, in the jud
4、gement 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 objections be considered, and that a conc
5、erted 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 usingproducts, processes, or procedures not
6、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 of an American National Standard in th
7、e 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 any time. The procedures of the America
8、n 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 Institute.American National StandardPu

However,
11、 nei-ther the developers nor the publisher have undertaken a patent search in order to identify which, ifany, patents may apply to this standard. As of the date of publication of this standard, followingcalls for the identification of patents that may be required for the implementation of the standa
12、rd,notice of one or more such claims has been received. By publication of this standard, no positionis taken with respect to the validity of this claim or of any rights in connection therewith. The knownpatent holder(s) has (have), however, filed a statement of willingness to grant a license underth
13、ese rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to ob-tain such a license. Details may be obtained from the publisher. No further patent search is con-ducted by the developer or publisher in respect to any standard it processes. No representation ismade or
14、implied that this is the only license that may be required to avoid infringement in the use ofthis standard.iContents1 Scope . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 12 Normative references . . . . . . . .
