IEC 60793-2-10:2011 is applicable to optical fibre types A1a, A1b, and A1d. These fibres are used or can be incorporated in information transmission equipment and optical fibre cables. Other applications include, but are not restricted to, the following:
- short reach,
- high bit-rate systems in telephony,
- distribution and local networks carrying data,
- voice and/or video services;
- on-premises intra-building and inter-building fibre installations including Data Centres, LANs, Storage Area Networks, PBXs, video, various multiplexing uses, outside telephone cable plant use, and miscellaneous related uses. The major changes with respect to the previous edition are:
- addition of type A1a.3 fibre;
- reduction of core diameter tolerance from 3,0 to 2,5 mum for A1a fibres.
