These fibres are used or can be incorporated in information transmission equipment and optical fibre cables.<\/p>\n<p>Type A1a applies to 50\/125&nbsp;\u00b5m graded index fibre. Three bandwidth grades are defined as A1a.1, A1a.2 and A1a.3. Each of these bandwidth grades is defined for two levels of macrobend loss performance that are distinguished by \u201ca\u201d or \u201cb\u201d suffix. Those with suffix \u201ca\u201d are specified to meet traditional macrobend loss performance levels. Those with suffix \u201cb\u201d are specified to meet enhanced macrobend loss (i.e. lower loss) performance levels.<\/p>\n<p>Type A1b applies to 62,5\/125&nbsp;\u00b5m graded index fibre and A1d applies to 100\/140&nbsp;\u00b5m graded index fibre.<\/p>\n<p>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, local area networks (LANs), storage area networks (SANs), private branch exchanges (PBXs), video, various multiplexing uses, outside telephone cable plant use, and miscellaneous related uses.<\/p>\n<p>Three types of requirements apply to these
