PD ISO/IEC TR 11801-9905:2018

This part of ISO/IEC11801, which is a Technical Report, provides guidance on how to select and assess installed channels which conform to ISO/IEC11801‑1, and clarify if they also support ISO/IEC/IEEE8802‑3:2017/AMD3 for 25GBASE-T; specifies the methods to assess whether installed channels constructed with Category7A, 7, or 6A components meet the 25GBASE-T requirements; provides guidance to identify which channels are likely to meet the 25GBASE-T requirements to avoid unnecessary testing; provides mitigation techniques to improve the performance of installed channels to meet the 25GBASE-T requirements; provides cabling recommendations for new installations. NOTE1 The channel transmission performance specified in this document is derived from the 25GBASE-T requirements in ISO/IEC/IEEE8802‑3:2017/AMD3. NOTE2 This document does not re-specify component or channel definitions of ISO/IEC11801‑1.
