BS EN IEC 63267-1:2023

This standard BS EN IEC 63267-1:2023 Fibre optic interconnecting devices and passive components. fibre optic connector optical interfaces is classified in these ICS categories:

• 33.180.20 Fibre optic interconnecting devices
• 33.180.10 Fibres and cables

This part of IEC 63267 covers multimode fibre optic connection interfaces. It includes references, document structure details, definitions, and standardised optical connection grades. The grades are based on random mated connections between two optical connector populations according to prescribed characteristics including the core diameter and numerical aperture mismatches. The document describes the rules under which an optical interface is created. It also defines standardised test methods where appropriate.
