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