Optical fibres - Part 2-20: Product specifications - Sectional specification for category A2 multimode fibres

IEC 60793-2-20:2015(E) is applicable to sub-categories A2a, A2b, and A2c. These fibres are used or can be incorporated in information transmission equipment and optical fibre cables (typically up to 2 km). Three types of requirements apply to these fibres: - general requirements as defined in IEC 60793-2; - specific requirements common to the category A2 multimodal fibres covered in this standard and which are given in Clause 3; - particular requirements applicable to individual sub-categories or specific applications, which are defined in the normative family specification annexes. This third edition cancels and replaces the second edition, published in 2007. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - Nath has been replaced by NAff; - specified test specimen length and measurement details for core diameter and NAff measurements. Keywords: information transmission equipment, optical fibre cables, category A2 multimodal fibres

Fibres optiques - Partie 2-20: Spécifications de produits - Spécification intermédiaire pour les fibres multimodales de catégorie A2

L'IEC 60793-2-20:2015 est applicable aux fibres optiques des sous-catégories A2a, A2b, et A2c. Ces fibres sont utilisées ou peuvent être intégrées dans des équipements pour la transmission de l'information et dans des câbles à fibres optiques (typiquement jusqu'à 2 km). Trois types d'exigences s'appliquent à ces fibres: - les exigences générales, qui sont définies dans l'IEC 60793-2; - des exigences spécifiques communes aux fibres multimodales de catégorie A2, couvertes par la présente norme, et qui sont données dans l'Article 3; - des exigences particulières applicables à des sous-catégories particulières de fibres ou à des applications données, qui sont définies dans les spécifications de famille figurant en annexe. Cette troisième édition annule et remplace la deuxième édition parue en 2007. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - NAth a été remplacé par NAff; - la longueur du spécimen d'essai et les détails de mesure spécifiés pour la mesure du diamètre du coeur et de NAff. Mots clés: des équipements pour la transmission de l'information, des câbles à fibres optiques, fibres multimodales de catégorie A2

Optična vlakna - 2-20. del: Specifikacije izdelka - Področna specifikacija za večrodna mehanska vlakna kategorije A2 (IEC 60793-2-20:2015)

Ta del standarda IEC 60793 se uporablja za podkategorije A2a, A2b in A2c. Ta vlakna se uporabljajo oziroma jih je mogoče vgraditi v opremo za prenos informacij in optične kable (običajno do največ 2 km).
Za ta vlakna veljajo tri vrste zahtev:
• splošne zahteve, kot so opredeljene v standardu IEC 60793-2;
• posebne zahteve, ki so skupne večrodnim vlaknom kategorije A2 iz tega standarda in so navedene v točki 3;
• posebne zahteve, ki veljajo za posamezne podkategorije ali posebne načine uporabe in so opredeljene v normativnih dodatkih o skupinski specifikaciji.
