IEC 60793-2-30:2012

Optical fibres - Part 2-30: Product specifications - Sectional specification for category A3 multimode fibres

IEC 60793-2-30:2012 is applicable to sub-categories A3a, A3b, A3c, A3d and A3e. 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 third edition cancels and replaces the second edition, published in 2007. It constitutes a technical revision and includes the following significant technical changes with respect to the previous edition:
- addition of a new sub-category A3e;
- changed unit for core-cladding concentricity error and proof stress level. Keywords: A3 multimode fibres, sub-categories A3a, A3b, A3c, A3d and A3e

La CEI 60793-2-30:2012 est applicable aux sous-catégories A3a, A3b, A3c, A3d et A3e. Trois types d'exigences s'appliquent à ces fibres:
- les exigences générales, comme définies dans la CEI 60793-2;
- des exigences spécifiques communes aux fibres multimodales de catégorie A3, couvertes par la présente norme, et qui sont données dans l'Article 3;
- des exigences particulières applicables à des sous-catégories particulières ou à des applications spécifiques (comme des applications automobiles ou industrielles), qui sont définies dans les annexes normatives relatives aux sous-catégories. Cette troisième édition annule et remplace la deuxième édition publiée en 2007. Elle constitue une révision technique La présente édition contient les modifications techniques significatives suivantes par rapport à l'édition précédente:
- l'ajout d'une nouvelle sous-catégorie A3e;
- modification d'unité concernant l'erreur de concentricité entre le coeur et la gaine et le niveau de contrainte d'essai. Mots clés: multimodales de catégorie A3, sous-catégories A3a, A3b, A3c, A3d et A3e

with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
