This part of IEC 60793\u20112<\/span> <\/span> is applicable to category A4 optical multimode fibres and the related sub-categories A4a, A4b, A4c, A4d, A4e, A4f, A4g and A4h. These fibres have a plastic core and plastic cladding and may have step-index, multi-step index or graded-index profiles. The fibres are used in information transmission equipment and other applications employing similar light transmitting techniques, and finally in fibre optic cables. Table 1<\/span> summarizes some of the salient characteristics and applications of these fibres.<\/p>\n

Other potential wavelengths for A4a fibre are described in Annex J<\/span>.<\/span><\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n

In addition to the applications shown in Table 1<\/span>, 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
  • \n

    general requirements, as defined in IEC 60793\u20112<\/span> <\/span> ;<\/p>\n<\/li>\n

  • \n

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

  • \n

    particular requirements applicable to individual fibre sub-categories and implementations or specific applications which are defined in this standard, in the normative family specification annexes.<\/p>\n<\/li>\n<\/ul>\n
