IEC 60875-1 Ed. 7.0 b:2024 PDF

This part of IEC 60875 applies to non-wavelength-selective fibre optic branching devices, all exhibiting the following features:
– they are passive, in that they contain no optoelectronic or other transducing elements;
– they have three or more ports for either the entry or exit, or both, of optical power, and share optical power among these ports in a predetermined fashion;
– the ports are optical fibres, or optical fibre connectors.

This document establishes uniform requirements for the optical, mechanical and environmental properties.
