Description

IEC 60793-2-40:2015(E) 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
