1 Scope
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 the entry and/or exit of optical power, and share optical power among these ports in a predetermined fashion;
-
– the ports are optical fibres, or optical fibre connectors.
This standard establishes uniform requirements for the optical, mechanical and environmental
properties.
