ISO/IEC 11801-2:2017

Overview

ISO/IEC 11801-2:2017 - "Information technology - Generic cabling for customer premises - Part 2: Office premises" specifies the requirements for structured cabling systems used within and between buildings of office premises or office spaces inside other building types. First published in 2017, this part of the ISO/IEC 11801 series focuses on office-specific design, installation and performance considerations and is intended to be read together with ISO/IEC 11801-1 (general requirements).

Key Topics

The standard addresses practical and technical aspects of generic cabling for offices, including:

• System structure and hierarchy: Functional elements (work area, horizontal cabling, backbone/campus cabling, telecommunications rooms) and options such as centralized architectures.
• Cabling media: Requirements for balanced copper cabling and optical fibre cabling, and guidance on component selection.
• Channel and link performance: Transmission and environmental performance requirements for channels, permanent links and cords.
• Cabling components: Specifications for cables, connecting hardware (patch panels, outlets), cords (work area and equipment cords), jumpers and patch cords.
• Installation and accommodation: Guidance for telecommunications rooms, equipment rooms, consolidation points and space planning to accommodate functional elements.
• Reference implementations and modelling: Typical horizontal cabling models, backbone/horizontal channel examples and dimensioning principles used for design and verification.
• Conformance and documentation: Normative references, terms and definitions, and conformance considerations to ensure interoperability and consistent performance.

Applications and Who Uses It

ISO/IEC 11801-2:2017 is a practical resource for professionals involved in office network infrastructure:

• Network architects and designers - to define cabling topology and specify media for performance targets.
• Cabling contractors and installers - for installation practices, component selection and testing criteria.
• IT managers and facilities planners - to plan telecommunications rooms, consolidation points and future-proof office layouts.
• Procurement and compliance teams - to develop specifications, acceptance tests and supplier contracts.
• Consultants and auditors - to assess conformance, validate performance and document cabling systems.

Use cases include new office fit-outs, retrofits, multi‑building office campuses and upgrades to support higher-speed Ethernet and fibre deployments.

Related Standards

• ISO/IEC 11801-1 (General) - read in conjunction for channel and link specifications.
• ISO/IEC 11801-3 - industrial spaces.
• ISO/IEC 11801-5 - data centre spaces.
• ISO/IEC 11801-6 - distributed building services.
