ISO/IEC 11801-6:2017

Overview

ISO/IEC 11801-6:2017 - "Information technology - Generic cabling for customer premises - Part 6: Distributed building services" specifies generic cabling for premises that comprise single or multiple buildings on a campus. The standard addresses both balanced cabling (twisted-pair) and optical fibre cabling, defining architecture, performance, components and implementation guidance for distributed building services and campus/backbone topologies.

Key topics and technical requirements

• Scope and structure: Defines the generic cabling system structure, including Type A and Type B generic cabling models, functional elements and hierarchical relationships for campus and building deployments.
• Cabling subsystems: Covers campus/building backbone cabling and service distribution cabling (Type A and Type B), with guidance on design objectives and accommodation of service outlets and concentration points.
• Performance requirements: Specifies channel and link performance requirements for balanced cabling and optical fibre cabling, including environmental performance parameters and test interfaces.
• Dimensioning and configuration: Provides rules for dimensioning cabling systems, positioning of telecommunications rooms, service concentration points (SCPs), and the layout of service outlets (SOs). Reference implementations and maximum channel lengths are supplied to support planning.
• Components and hardware: Details requirements for cables, connecting hardware, and cords/jumpers-including electrical, mechanical and environmental performance expectations.
• Reference implementations & annexes: Includes practical reference models, implementation recommendations (including optical fibre in Type B subsystems), and informative annexes on services, overlay architectures and SCP grid densities.

Practical applications and intended users

ISO/IEC 11801-6 is used whenever a standardized, vendor-neutral cabling design is required across multi-building or complex premises. Typical users include:

• Network designers and system architects planning campus and multi-building networks
• Cabling contractors and installers implementing balanced and fibre systems
• Facility and building managers specifying cabling for building services (security, building management, AV, energy and environmental control)
• IT integrators, consultants and spec writers creating procurement documents and compliance evidence

The standard helps ensure predictable performance, interoperability, maintainability and future-proofing of building services cabling.

Related standards

• ISO/IEC 11801 (the overall generic cabling family) and its other parts (see Figure 1 in the document for relationships).
• Produced under ISO/IEC JTC 1/SC 25 (standards committee for information technology cabling).
