- 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;
