2、signed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, facilitating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for his particular need. Existence
3、 of such Specifications and Publications shall not in any respect preclude any member or nonmember of ECIA from manufacturing or selling products not conforming to such Specifications and Publications, nor shall the existence of such Specifications and Publications preclude their voluntary use by th
4、ose other than ECIA members, whether the standard is to be used either domestically or internationally. Specifications and Publications are adopted by ECIA in accordance with the American National Standards Institute (ANSI) patent policy. By such action, ECIA does not assume any liability to any pat
5、ent owner, nor does it assume any obligation whatever to parties adopting the Specification or Publication. This EIA specification is considered to have International Standardization implications, but the International Electrotechnical Commission activity has not progressed to the point where a vali
6、d comparison between the EIA standard and the IEC document can be made. This Specification does not purport to address all safety problems associated with its use or all applicable regulatory requirements. It is the responsibility of the user of this Specification to establish appropriate safety and
7、 health practices and to determine the applicability of regulatory limitations before its use. NOTE The users attention is called to the possibility that compliance with this standard may require use of an invention covered by patent rights. By publication of this standard, no position is taken with
8、 respect to the validity of any such claim(s) or of any patent rights in connection therewith. If a patent holder has filed a statement of willingness to grant a license under these rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain such a license, then
9、details may be obtained from the standards developer. Neither the standards developer nor ANSI is responsible for identifying patents for which a license may be required by an American National Standard or for conducting inquiries into the legal validity or scope of those patents that are brought to
10、 their attention.

This Specification is from EIA Standards Proposal No. 5331, formulated
41、 under the cognizance of EIA CE-2.0, Committee on Connector and Socket Standards. This project was conducted in liaison with the SFF Committee as representing the disk drive industry. Utilization of this Standard is intended to eliminate misunderstandings or confusion between a manufacturer and user
42、 with respect to product performance and testing requirements for this as well as other possible applications. The development work on this specification was done by the SFF Committee, an industry group. The membership of the committee since its formation in August 1990 has included a mix of compani
43、es which are leaders across the industry. viii Background Abstract: This specification defines the electrical (copper), the optical and the mechanical characteristics of the pluggable Quad SFP+ Module/direct attach cable plug and connector. This document provides a common specification for systems m
44、anufacturers, system integrators, and suppliers of drives. This specification is made available for public review, and written comments are solicited from readers. Comments received by the members will be considered for inclusion in future revisions of this specification. EIA-964 Page 1 Specificatio
