Overview

EN IEC 60794-2-11:2019/A1:2021 is the CLC-endorsed amendment to the international standard that defines detailed specifications for indoor optical fibre cables - specifically simplex and duplex constructions intended for premises cabling. Amendment A1 updates guidance on minimum multimode fibre bandwidth and adds effective modal bandwidth guidance in the 840 nm to 953 nm wavelength range. This amendment aligns the European adoption (EN IEC) with IEC developments and clarifies multimode performance expectations for OM3, OM4 and OM5 fibres.

Key Topics

  • Scope: Detailed requirements for simplex and duplex indoor optical-fibre cables used in building and premises cabling applications.
  • Amendment focus: Updates to the minimum multimode fibre bandwidth table and new guidance for effective modal bandwidth in the 840 nm–953 nm range.
  • Multimode bandwidth guidance: The amendment references IEC 60793-2-10 for effective modal bandwidth guidance; the note in the amendment provides example guidance values at 953 nm (OM3 guidance 1 033 MHz·km; OM4 guidance 1 459 MHz·km).
  • Compliance and harmonization: The amendment was approved by CENELEC and adopted as EN IEC 60794-2-11:2019/A1:2021 to ensure consistent national implementation across CENELEC members.

Practical keywords: indoor optical fibre cables, simplex duplex, premises cabling, OM3 OM4 OM5, effective modal bandwidth, installation guidance, cable performance.

Applications

This standard and its amendment are directly relevant to organizations specifying, procuring, designing or installing fibre infrastructure within buildings and campuses. Typical applications include:

  • Office and enterprise LAN backbone and horizontal cabling
  • Educational and healthcare facility premises cabling
  • Retail and commercial building network installations
  • Small data room and telecom closet optical links where simplex or duplex fibres are deployed

Benefits for users:

  • Clear performance expectations for multimode fibre types (OM3/OM4/OM5), aiding component selection.
  • Improved interoperability and harmonized national implementation across European markets.
  • Better design guidance for installers and network designers via updated effective modal bandwidth information in the 840–953 nm range.

Related Standards

  • IEC 60794-2-11 (base publication): detailed specification for indoor simplex and duplex cables (this amendment updates that document).
  • IEC 60793-2-10: referenced for effective modal bandwidth guidance across the 840 nm–953 nm wavelength range.
  • IEC 60794 series: broader family covering optical fibre cables and their tests, constructions and performance characteristics.

For procurement, specification writing and installation planning, reference EN IEC 60794-2-11:2019/A1:2021 to ensure compliant indoor fibre cable selection and to take advantage of the updated multimode bandwidth guidance for modern premises cabling deployments.
