标准摘要
[中文适用范围]： IEC 60793-2的本部分适用于A4类多模光纤及相关子类A4a、A4b、A4c、A4d、A4e、A4f、A4g和A4h。这些光纤具有塑料芯和塑料包层，并且可以具有阶跃折射率、多阶折射率或渐变折射率分布。这些光纤用于信息传输设备和其他采用类似光传输技术的应用，最后用于光纤电缆。 [外文原描述]： IEC 60793-2-40:2015 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 of this document summarizes some of the salient characteristics and applications of these fibres. This fourth edition cancels and replaces the third edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - harmonization of terminology within the IEC 60793-2 series; - added measurement parameters for numerical aperture and fibre geometry. Keywords: category A4 optical multimode fibres, information transmission equipment
