This part of ISO\/IEC 11801, which is a Technical Report, provides definitions for, and examples of, direct attach cabling configurations.<\/p>\n

This document provides performance specifications for Classes D, E, EA<\/sub>, F, FA<\/sub>, I and II direct attach cabling by reference to ISO\/IEC 11801-1.<\/p>\n

Informative limits for Class I direct attach cabling to support 5 m short reach mode application according to ISO\/IEC\/IEEE 8802-3:2017\/AMD3, i.e. 25GBASE-T and 40GBASE-T, are provided in Annex A.<\/p>\n

Test methods will be provided in the second edition of ISO\/IEC 14763-4.<\/p>\n

\n

NOTE ISO\/IEC 14763-4 is the test method for End to End (E2E) link. It can be also used for direct attach cabling. Test methods for Classes EA<\/sub>, F, FA<\/sub>, I, II will be provided in the second edition of ISO\/IEC 14763-4.<\/p>\n<\/blockquote>\n

Direct attach cabling connects two pieces of equipment, it has connectors at each end, and no intermediate connecting hardware.<\/p>\n
