ISO/IEC 11801-1:2017/Amd 1:2025/Cor 1:2025

Overview

ISO/IEC 11801-1:2017/Amd 1:2025/Cor 1:2025 is a technical corrigendum to the international standard for Generic Cabling for Customer Premises. This amendment updates the general requirements specified in Part 1 of ISO/IEC 11801-1:2017. The corrigendum mainly addresses clarifications and corrections to the documented specifications, ensuring enhanced accuracy and consistency in the implementation of generic cabling systems.

Maintained by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC), this standard is critical for designers, installers, and users of structured cabling systems in commercial, residential, and industrial premises.

Key Topics

• Amendment 1 Updates
  The amendment revises existing clauses to improve technical precision and resolve inconsistencies in the original 2017 edition.

• Technical Corrigendum 1 Adjustments
  Specific corrections include modifying Table 181 by deleting certain footnotes (c, d, and e) related to power sum alien attenuation to crosstalk ratio (ACR-F) values (PS AACR-F). This correction impacts the way Class parameters are referenced and used.

• Power Sum Alien ACR-F (PS AACR-F)
  This parameter relates to the performance characteristics of cabling systems combating interference and crosstalk between connectors and cables, ensuring reliable high-speed data transmission.

Applications

• Structured Cabling Design
  Provides detailed guidance on the design of generic cabling infrastructure in customer premises, supporting networking stability and scalability.

• Installation and Compliance
  Helps installers comply with internationally recognized standards, reducing errors during deployment and ensuring compatibility across various cabling components.

• Network Performance Assurance
  By updating definitions and measurement criteria, this corrigendum helps maintain optimal cabling performance, essential for high-speed communication systems in data centers, office buildings, and smart facilities.

• Future-Proofing Cabling Systems
  The amendments align cabling specifications with current technology trends, enhancing the capability of supporting emerging applications such as IoT, 5G infrastructure, and cloud computing.
