This part of IEC60793‑2 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. Table1 summarizes some of the salient characteristics and applications of these fibres. Table1 Characteristics and applications of category A4 fibres Sub-category A4a A4b A4c A4d A4e A4f A4g A4h Core diameter (µm) See Note 1 See Note 1 See Note 1 See Note1 ≥500 200 120 62,5 Cladding diameter (µm) 1000 750 500 1000 750 490 490 245 Numerical aperture Naff 0,50 0,50 0,50 0,30 0,25 0,190 0,190 0,190 Operating wave- length (s) (nm) 650 See Note2 650 650 650 650 650 850 1300 650 850 1300 850 1300 Applica-tions Digital audio interface, automobile, industrial, sensor and data transmission Indus- trial and sen-sor Sen-sor Digital audiovisual interface and data transmission Digital audiovisual interface and data transmission Industrial and mobile; compatible with A3 transmission equipment Data transmission Data transmission; primarily used in ribbon structures NOTE1 Typically 15µm to 35µm smaller than the cladding diameter. NOTE2 Other potential wavelengths for A4a fibre are described in AnnexJ. In addition to the applications shown in Table1, 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 IEC60793‑2 ; specific requirements common to category A4 multimode fibres covered in this standard and which are given in Clause3; 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.
