IEC 60793-2-30:2015（E9适用于A3a、A3b、A3c、A3d、A3e、A3f和A3g子类别。这些光纤用于或可并入不同的信息传输设备、采用类似光传输技术的其他应用以及光纤电缆。三类要求适用于这些光纤: -IEC 60793-2中定义的一般要求； -本标准涵盖的A3类多模光纤共有的具体要求，在第3条中给出； -适用于各个子类别或特定应用（例如汽车或工业应用）的特定要求，这些要求在规范性子类别附件中定义。第四版取消并取代了2012年出版的第三版，构成技术修订。与上一版相比，此版本包括以下重大技术变更: -增加了芯直径和NAff测量的指定试样长度和测量细节； -增加了两个新的子类别； -纳特被纳夫取代。 关键词:A3类多模光纤

IEC 60793-2-30:2015(E9 is applicable to sub-categories A3a, A3b, A3c, A3d, A3e, A3f and A3g. These fibres are used or can be incorporated in different information transmission equipment, other applications employing similar light transmitting techniques as well as fibre optic cables. Three types of requirements apply to these fibres:
- general requirements, as defined in IEC 60793-2;
- specific requirements common to the category A3 multimode fibres covered in this standard and which are given in Clause 3;
- particular requirements applicable to the individual sub-categories or specific applications (e.g. automotive or industrial applications), which are defined in the normative sub-category annexes. This fourth edition cancels and replaces the third edition published in 2012 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- specified test specimen length and measurement details for core diameter and NAff measurements have been added;
- two new sub-categories have been added;
- NAth is replaced by Naff. Keywords: category A3 multimode fibres
