UNE EN IEC 61280-4-1:2019
This document is applicable to the measurement of attenuation of installed optical fibre cabling plant using multimode optical fibre. This cable plant can include multimode optical fibres, connectors, adapters, splices, and other passive devices. The cabling may be installed in a variety of environments including residential, commercial, industrial, and data centre premises, as well as outside plant environments. The test equipment used in this standard has a single fibre connector interface to test one fibre at a time; or sometimes a duplex interface that may be used to test a pair of fibres, often testing one fibre of the pair in each direction. In this standard, the optical fibres that are addressed include sub-categories A1-OMx, where x = 2, 3, 4 and 5 (50/125 ¼m) and A1-OM1 (62,5/125 ¼m) multimode optical fibres, as specified in IEC 60793-2-10. The attenuation measurements of the other multimode categories can be made using the approaches of this standard, but the source conditions for the other categories have not been defined.
