CSA ISO/IEC TR 11801-9905:19
Information technology — Generic cabling for customer premises — Part 9905: Guidelines for the use of installed cabling to support 25GBASE-T application (Adopted ISO/IEC TR 11801-9905:2018, first edition, 2018-02)
Standards development within the Information Technology sector is harmonized with international standards development. Through the CSA Technical Committee on Information Technology (TCIT), Canadians serve as the SCC Mirror Committee (SMC) on ISO/IEC Joint Technical Committee 1 on Information Technology (ISO/IEC JTC1) for the Standards Council of Canada (SCC), the ISO member body for Canada and sponsor of the Canadian National Committee of the IEC. Also, as a member of the International Telecommunication Union (ITU), Canada participates in the International Telegraph and Telephone Consultative Committee (ITU-T).
The ISO/IEC Technical Report was reviewed by the CSA TCIT under the jurisdiction of the CSA Strategic Steering Committee on Information and Communications Technology and deemed acceptable for use in Canada. From time to time, ISO/IEC may publish addenda, corrigenda, etc. The TCIT will review these documents for approval and publication. For a listing, refer to the Current Standards Activities page at standardsactivities.csa.ca. This Standard has been formally approved, without modification, by the Technical Committee and has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
This part of ISO/IEC 11801, which is a Technical Report
a) provides guidance on how to select and assess installed channels which conform to ISO/IEC 11801-1, and clarify if they also support ISO/IEC/IEEE 8802-3:2017/AMD3 for 25GBASE-T;
b) specifies the methods to assess whether installed channels constructed with Category 7A, 7, or 6A components meet the 25GBASE-T requirements;
c) provides guidance to identify which channels are likely to meet the 25GBASE-T requirements to avoid unnecessary testing;
d) provides mitigation techniques to improve the performance of installed channels to meet the 25GBASE-T requirements;
e) provides cabling recommendations for new installations.
NOTE 1 The channel transmission performance specified in this document is derived from the 25GBASE-T requirements in ISO/IEC/IEEE 8802-3:2017/AMD3.
NOTE 2 This document does not re-specify component or channel definitions of ISO/IEC 11801-1.
