IEC 60794-2-30:2019 PDF

Overview

IEC 60794-2-30:2019 is an IEC family specification for indoor optical fibre ribbon cables intended for use in terminated cable assemblies. Focused on defining flat ribbon cables, this third edition (replacing the 2008 edition) provides construction, dimension, performance and test requirements specific to ribbon-style indoor cabling used in premises and data‑centre environments. Annex B adds alternative requirements where cables are installed under the MICE environmental classification.

Key topics and technical requirements

The standard addresses the full ribbon-cable lifecycle from design to verification, including:

• Construction and materials
  • Ribbon structure, optical fibres and primary coating, buffers, sheath, ripcord, strength/anti‑buckling members and identification/colour coding.
• Dimensions and geometry
  • Defined ribbon and cable geometry for flat ribbon constructions and related dimension limits.
• Mechanical tests
  • Cable tensile performance, crush, impact, bending (including repeated and bending under tension), flexing, torsion and kink tests.
• Environmental tests
  • Temperature cycling and related environmental requirements; Annex B provides alternative conditions for MICE-classified installations.
• Transmission requirements
  • Cabled attenuation and transmission limits for multiple single-mode and multimode fiber categories (tables in the standard define applicable values).
• Fire performance
  • Fire behaviour and marking requirements relevant to indoor deployment and terminated assemblies.
• Documentation and family specification
  • Blank detail specification templates in Annex B for family-based product definition (enables product variants under a single family spec).

Notable editorial/technical updates in this edition: removal of Annex C, references updated to the most recent fibre standards, and added cross-references to IEC 60794-1-21/1-22/1-23/1-24.

Practical applications and users

IEC 60794-2-30:2019 is used by:

• Cable manufacturers designing and certifying indoor flat ribbon cables for patch cords, trunking and terminated assemblies.
• System designers and specifiers selecting ribbon cables for premises cabling, data centres, central offices and telecom rooms.
• Installers and contractors ensuring installed ribbon cables meet mechanical, environmental and fire requirements for indoor spaces.
• Test laboratories and conformity bodies performing the mechanical, environmental and transmission tests described. Practical use cases include high-density backbone/trunk cabling, MPO/MTP terminated assemblies, and horizontal/cross‑connect installations where rapid mass-fibre termination is required.
