This part of IEC 60793-2 is applicable to optical fibre categories A4a@ A4b@ A4c@ A4d@ A4e@ A4f@ A4g and A4h. These fibres have a plastic core and plastic cladding and may have stepindex@ multi-step index@ or graded-index profiles. The fibres are used in information transmission equipment and optical fibre cables. Table 1 summarizes some of the salient characteristics and applications of these fibres. In addition to the applications shown in Table 1@ other applications for A4 fibres include@ but are not restricted to@ the following: support for short reach high bit-rate systems in telephony@ distribution and local networks@ carrying data@ voice and/or video services and on-premises intrabuilding and interbuilding fibre installations@ including LANs@ PBXs@ video@ various multiplexing uses@ and miscellaneous related uses@ such as consumer electronics and industrial and mobile networks. Three types of requirements apply to A4 fibres: ? general requirements@ as defined in IEC 60793-2; ? specific requirements common to category A4 multimode fibres covered in this standard and that are given in Clause 3; ? particular requirements applicable to individual fibre types or specific applications and that are defined in this standard in the normative family specification annexes.
