scope:
This International Standard, IEC 61280-4-1, is applicable to the measurement of attenuation of installed fibre-optic cabling using multimode fibre, typically in lengths of up to 2 000 metres.
This cabling can include multimode fibres, connectors, adapters and splices.
Cabling design standards such as ISO/IEC 11801, ISO/IEC 24702 and ISO/IEC 24764 contain specifications for this type of cabling. ISO/IEC 14763-3 which supports these design standards makes reference to the test methods of this standard.
In this edition, the fibre types that are addressed include category A1a (50/125 µm) and A1b (62,5/125 µm) multimode fibres as specified in IEC 60793-2-10. The link attenuation measurements of the other multimode categories can be done using the approaches of this document, but the source conditions for the other categories have not been defined.
