BS EN IEC 63267-3-61:2025

This standard BS EN IEC 63267-3-61:2025 Fibre optic interconnecting devices and passive components. Fibre optic connector optical interfaces for enhanced macrobend multimode fibres is classified in these ICS categories:

• 33.180.20 Fibre optic interconnecting devices

IEC 63267-3-61: 2025 defines the dimensional limits of an optical interface for reference connectors with 2,5 mm or 1,25 mm diameter cylindrical zirconia (ZrO2) ferrules necessary to meet specific requirements for fibre-to-fibre interconnection of non-angled polished multimode reference connections as defined in IEC 63267-2-2. Ferrule dimensions and features are contained in the IEC 61754 series of fibre optic connector interface standards. One grade of reference connector, Rm1, is defined in this document. The reference connector is terminated to restricted IEC 60793-2-10 using A1-OM2b to A1‑OM5b fibre in 850 nm band only. The geometrical dimensions and tolerances of the specified reference connector have been developed primarily to limit the variation in measured attenuation between multiple sets of reference connectors, and therefore to reduce the variation in measured attenuation between an arbitrarily chosen reference connector when mated with a connector in the field or factory. This first edition and the first edition of IEC 63267-2-2 cancel and replace the first edition of IEC 61755-6-2 published in 2018. This edition constitutes a technical revision. The document includes the following significant technical changes with respect to the previous edition: a) Definition of a reference grade, Rm1 interface; b) Inclusion of A1-OM2b to A1-OM5b fibres; c) Updates to normative references; d) The addition of Annex A, which describes the attenuation test limits of reference grade Rm1 connectors to grade Bm connectors; e) A new Annex B that describes the allowable fibre undercut.
