Overview

IEC 60793-2-40:2015 - Optical fibres - Part 2-40: Product specifications - Sectional specification for category A4 multimode fibres - defines product and test requirements for category A4 optical multimode fibres (and sub-categories A4a–A4h). These fibres feature a plastic core and plastic cladding and may use step‑index, multi‑step index or graded‑index refractive profiles. The 2015 (4th) edition replaces the 2009 edition and is a technical revision that harmonizes terminology across the IEC 60793-2 series and adds measurement parameters for numerical aperture and fibre geometry.

Key topics and technical requirements

The standard organizes requirements into clear, testable sections:

Dimensional requirements - geometry, core/cladding dimensions and measurement methods.
Mechanical requirements - tensile strength, elongation/tensile load tests and other mechanical attributes.
Transmission requirements - attenuation, bandwidth and modal performance for multimode operation.
Environmental requirements - exposure tests and limits for stability under temperature, humidity and mechanical stress.
Family/sub-category specifications (Annexes A–H) - tailored attributes and limits for A4a through A4h fibres.
Mode scrambler specification (Annex I) - requirements for mode scramblers used with A4a–A4d fibres to ensure repeatable modal launch conditions.
Additional transmission rules (Annex J) - extra requirements for A4a fibres operating below 650 nm.

Tables throughout the document summarize characteristics, measurement methods and pass/fail criteria to support consistent testing and procurement.

Applications and who uses this standard

IEC 60793-2-40:2015 is intended for stakeholders involved in the design, manufacture, testing and procurement of plastic optical multimode fibres and related systems:

Fibre manufacturers - to design and certify A4 family fibres to defined product specifications.
Cable and connector producers - to ensure component compatibility and mechanical robustness.
Test laboratories and QA teams - to perform dimensional, mechanical, transmission and environmental tests per standardized methods.
Systems integrators and equipment designers - especially for information transmission equipment and other light‑transmitting applications using plastic multimode fibres.
Procurement and compliance officers - to specify clear acceptance criteria in contracts and product datasheets.

Measurement and test standards referenced within IEC 60793-2-40 for attenuation, numerical aperture and geometry measurements.

IEC 60793-2-40:2015 is the authoritative reference for specifying and verifying category A4 optical multimode fibres in commercial and industrial optical transmission applications.
