Optical fibre cables - Part 3-20: Outdoor cables - Family specification for self-supporting aerial telecommunication cables

IEC 60794-3-20:2008(E) covers optical self-supporting aerial telecommunication cables. Requirements of the sectional specification IEC 60794-3 for duct, buried and aerial cables are applicable to cables covered by this standard. This second edition cancels and replaces the first edition published in 2002. It constitutes a technical revision. The main changes are listed below: - the fibres specification clause (Clause 5) has been enlarged to include fibre Types B5 and B6.a; - an annex has been added for additional requirements according to the MICE table.

Câbles à fibres optiques - Partie 3-20: Câbles extérieurs - Spécification de famille pour les câbles de télécommunication aériens autoporteurs

IEC 60794-3-20:2009 s'applique aux câbles optiques de télécommunication aériens autoporteurs. Les exigences de la spécification intermédiaire IEC 60794-3 pour les câbles installés dans des conduites, enterrés et aériens sont applicables aux câbles couverts par la présente norme. Dans ce contexte, on entend par câble de télécommunication aérien autoporteur un câble dont la construction intègre suffisamment d'éléments de renfort pour qu'il puisse être suspendu à des poteaux et des dispositifs analogues sans l'aide d'un autre fil ou conducteur de support. Les câbles ADSS et d'autres constructions destinées aux applications en haute tension ne sont pas couverts par la présente norme. Des spécifications particulières peuvent être établies en se basant sur la présente spécification de famille. L'Article A.2 contient des exigences qui remplacent les exigences normales dans le cas où les câbles sont destinés à être utilisés dans une installation régie par le tableau MICE de l'ISO/IEC 24702. Les paramètres spécifiés dans la présente norme peuvent être affectés par l'incertitude de mesure provenant soit d'erreurs de mesure, soit d'erreurs d'étalonnage en raison du manque de normes appropriées. Les critères d'acceptation doivent être interprétés en tenant compte de cela (voir l'IEC 60794-3, Article 8). Le nombre de fibres soumises aux essais doit être représentatif de la conception du câble et doit faire l'objet d'un accord entre le client et le fournisseur. Cette deuxième édition annule et remplace la première édition parue en 2002. Elle constitue une révision technique. Les modifications majeures sont: - l'article sur les spécifications de fibres (Article 5) a été développé pour inclure les fibres des types B5 et B6.a; - une annexe a été ajoutée pour des exigences supplémentaires conformément au tableau MICE.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
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 reason
