This part of IEC 60793 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.Type A1a fibre is a 50/125 ?m graded index fibre. Type A1a.1 (which was defined in the previous edition of this standard as type A1a) applies to 50/125 ?m fibre@ while A1a.2 applies to 850 nm laser-optimised 50/125 ?m fibre. Type A1b applies to 62@5/125 ?m graded index fibre and A1d applies to 100/140 ?m graded index fibre.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 and on-premises intra-building and inter-building fibre installations@ including LANs@ PBXs@ video@ various multiplexing uses@ outside telephone cable plant use@ and miscellaneous related uses.Three types of requirements apply to these fibres:?C general requirements@ as defined in IEC 60793-2;?C specific requirements common to the category A1 multimode fibres covered in this standard and which are given in Clause 3;?C particular requirements applicable to individual fibre types or specific applications@ which are defined in the normative family specification annexes.
