Optical fibres - Part 2-40: Product specifications - Sectional specification for category A4 multimode fibres
IEC 60793-2-40:2021 is available as IEC 60793-2-40:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60793-2-40:2021 is applicable to category A4 optical multimode fibres and the related subcategories A4a, A4b, A4c, A4d, A4e, A4g, A4h and A4i. 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 in fibre optic cables. Table 1 summarizes some of the salient characteristics and applications of these fibres. This fifth edition cancels and replaces the fourth edition published in 2015. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - revision of NA range of A4a.2; - addition of a new subcategory A4i; - deletion of the subcategory A4f and of Annex F.

IEC 60793-2-40:2021 est disponible sous forme de IEC 60793-2-40:2021 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 60793-2-40:2021 s'applique à la catégorie de fibres optiques multimodales A4 et à ses sous-catégories A4a, A4b, A4c, A4d, A4e, A4g, A4h et A4i. Ces fibres possèdent un cœur et une gaine en plastique et elles peuvent avoir des profils de type en saut d'indice, en sauts multiples d'indice ou en gradient d'indice. Les fibres sont utilisées dans les équipements destinés à la transmission de l'information et dans d'autres applications utilisant des techniques similaires de transmission du rayonnement lumineux, et dans des câbles fibroniques. Le Tableau 1 résume certaines des caractéristiques et applications principales de ces fibres. Cette cinquième édition annule et remplace la quatrième édition parue en 2015 dont elle constitue une révision technique. La présente édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - révision de la plage d'ouvertures numériques des fibres A4a.2; - ajout d'une nouvelle sous-catégorie A4i; - suppression de la sous-catégorie A4f et de l'Annexe F.
