ISO/IEC 11801-1:2017

Overview

ISO/IEC 11801-1:2017 - Information technology - Generic cabling for customer premises - Part 1: General requirements specifies the common, multi-vendor requirements for structured cabling on customer premises. This consolidated edition (including the April 2018 corrigendum and Amendment 1) defines a generic cabling system that can be implemented with components from single or multiple suppliers and that supports a wide range of services - voice, data, video and the provision of power.

Keywords: ISO/IEC 11801-1:2017, generic cabling, structured cabling standard, customer premises cabling, cabling performance.

Key topics and technical requirements

The standard establishes foundational requirements that apply across the ISO/IEC 11801 series. Major technical topics include:

• Structure of generic cabling - functional elements, interfaces, cabling subsystems (horizontal, backbone, common subsystems, tie cabling), channels and permanent links.
• Channel and link performance - specifications for balanced copper, coaxial and optical-fibre channels; link-level parameters and conformance criteria.
• Transmission parameters and tests - return loss, insertion loss/attenuation, NEXT, ACR (near- and far-end), alien crosstalk, propagation delay, delay skew, DC loop resistance and resistance unbalance.
• Cable types and categories - balanced copper categories (Category 5 to 7, 8.1, 8.2 and BCT-B), coaxial, optical fibre classes and single-pair cabling. Includes cable sharing and environmental classifications.
• Connecting hardware requirements - mechanical, electrical and environmental requirements for connectors and outlets, with references to IEC connector families (e.g., IEC 60603‑7, IEC 61076, IEC 61169, IEC 61754, IEC 63171).
• Reference backbone implementations - guidance on component selection and dimensions for backbone subsystems.
• Conformance, terminology and installation practice - definitions, test methods, marking, mounting and installation considerations.

Practical applications and users

ISO/IEC 11801-1 is used to design, specify, procure and verify structured cabling for:

• Commercial offices, multi-tenant buildings and campus networks
• Data centres and telecommunications rooms (backbone and horizontal cabling)
• Industrial and smart-building installations where cabling must support power delivery and diverse services
• Network integrators, cabling installers and test laboratories for acceptance testing and compliance
• Specifiers, facility managers, consultants and manufacturers for product development and documentation

Related standards

This Part 1 sets the general requirements that complement other parts of the ISO/IEC 11801 series (which address specific environments and cabling technologies). It also references connector and component standards from the IEC family (e.g., IEC 60603‑7, IEC 61076 series, IEC 61169, IEC 61754, IEC 63171).

For professionals seeking a vendor-neutral, standards-based approach to structured cabling, ISO/IEC 11801-1:2017 is the authoritative starting point to ensure interoperability, performance and future serviceability.
