Full title and description

Information technology — Generic cabling systems for customer premises — Part 9901: Guidance for balanced cabling in support of at least 40 Gbit/s data transmission. This Technical Report provides guidance on channel descriptions and performance considerations for balanced copper cabling intended to support 40 Gbit/s and higher within customer premises, including recommended channel classes and component characterizations.

Abstract

ISO/IEC TR 11801-9901:2014 defines channel descriptions constructed from components with a nominal impedance of 100 Ω and gives guidance on designs intended to support at least 40 Gbit/s. The report describes Class I and Class II 30 m channels (based on Category 8.1 and 8.2 components respectively), and also covers channels based on Category 6A and Category 7A components characterized or length-corrected to 30 m and to extended frequency ranges (up to 1 600 MHz and with consideration up to 2 000 MHz). Informative annexes assess cabling capacity for 40 Gbit/s and provide characterisation guidance using standardised components.

Scope

This Technical Report gives guidance for balanced copper cabling channels intended to support at least 40 Gbit/s data transmission within customer premises. It specifies and compares channel descriptions based on emerging Category 8.1 (Class I) and Category 8.2 (Class II) component sets (30 m channels), and also addresses how Category 6A and Category 7A components can be length-corrected or characterized for 30 m channels and for operation beyond their then-current upper frequency limits. The report is informative: it provides assessment methodology and characterization guidance rather than normative requirements.

Key topics and requirements

• Definition of Class I (Category 8.1-based) and Class II (Category 8.2-based) 30 m channels intended to provide sufficient margin for ≥40 Gbit/s operation.
• Guidance on extending characterization of Category 6A and Category 7A components to 30 m channels and to higher frequencies (characterisation beyond existing upper limits).
• Emphasis on components with nominal 100 Ω impedance and how component-level performance aggregates into channel performance for high-speed Ethernet.
• Informative assessment methods (annexes) for evaluating cabling capacity and characterizing channels using standardised components.
• Practical considerations for installers and system designers about margin, reach (30 m reference), and the relationship between cabling class and PHY requirements for multi-gigabit operation.

Typical use and users

Intended users include cabling system designers, installers, ICT infrastructure planners, network architects, manufacturers of cables and connectors, test-equipment vendors, and standards committees who need guidance on designing or assessing balanced copper cabling to support 40 Gbit/s links (especially where short-reach high-speed Ethernet over copper is considered). The report is used as informative guidance alongside the core ISO/IEC 11801 parts when planning high-performance premises cabling.

Related standards

ISO/IEC TR 11801-9901:2014 is part of the broader ISO/IEC 11801 family (Generic cabling for customer premises). Closely related documents and parts include ISO/IEC 11801-1 (general requirements) and other Technical Reports/Parts in the 990x series covering modelling, end-to-end link configurations and specific evaluations (for example ISO/IEC TR 11801-9902, ISO/IEC TR 11801-9903, and later 990x parts addressing evaluation for 25 Gbit/s and single-pair cabling). Users typically consult the relevant part(s) of ISO/IEC 11801 together with this TR for complete design and verification guidance.

FAQ

Q: What is this standard?

A: ISO/IEC TR 11801-9901:2014 is a Technical Report that provides guidance on balanced copper cabling intended to support at least 40 Gbit/s data transmission within customer premises. It is informative guidance (not a prescriptive international standard) published in October 2014.

Q: What does it cover?

A: It covers descriptions and guidance for short-reach (30 m) channel classes based on Category 8.1 and 8.2 components (Class I and Class II), approaches to characterize and length-correct Category 6A and 7A components for 30 m channels, and informative assessment methods (annexes) for evaluating cabling capacity to support 40 Gbit/s.

Q: Who typically uses it?

A: Cabling designers, network architects, installers, manufacturers (cable, connector, and test equipment), and technical committees use this TR as guidance when planning, specifying, or testing premises cabling intended for multi‑gigabit Ethernet applications.

Q: Is it current or superseded?

A: The document was published in October 2014 (Edition 1). As of publication it served as guidance; users should check the ISO/IEC catalogue or later parts of the 11801 series for amendments, newer Technical Reports, or Technical Specifications that may update or supersede specific guidance. For related updates and newer 990x parts consult the ISO catalogue entries for the 11801 series.

Q: Is it part of a series?

A: Yes — it is part of the ISO/IEC 11801 family (Generic cabling for customer premises) and specifically one of the 990x Technical Report/Technical Specification parts that provide additional guidance and modelling for high-performance cabling beyond the core normative parts. Other 990x documents address modelling, end-to-end link configurations, evaluation for particular data rates, and newer single-pair/copper guidance.
