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.<\/p>\n

NOTE 1 Typically 15\u03bcm to 35 \u03bcm smaller than the cladding diameter.<\/p>\n<\/blockquote>\n

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.<\/p>\n

Three types of requirements apply to A4 fibres:<\/p>\n

  • \n

    general requirements, as defined in IEC 60793-2;<\/p>\n<\/li>\n

  • \n

    specific requirements common to category A4 multimode fibres covered in this standard and that are given in Clause 3;<\/p>\n<\/li>\n

  • \n

    particular requirements applicable to individual fibre types or specific applications and that are defined in this standard in the normative family specification annexes.<\/p>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"
