Optical fibre cables - Part 3-20: Outdoor cables - Family specification for self supporting aerial telecommunication cable (IEC 60794-3-20:2009)

This part of IEC 60794 which is a family specification 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. Self-supporting aerial telecommunication cable in this context means a cable construction with sufficient strength members designed to be suspended on poles and similar devices without the aid of another supporting wire or conductor. ADSS cables and other constructions intended for high-voltage applications are not covered by this standard. Detail specifications may be prepared based on this family specification. Clause A.2 contains requirements that supersede the normal requirements in case the cables are intended to be used in installation governed by the MICE table of ISO/IEC 24702. The parameters specified in this standard may be affected by measurement uncertainty arising either from measurement errors or calibration errors due to lack of suitable standards. Acceptance criteria shall be interpreted with respect to this consideration (see IEC 60794-3, Clause 8). The number of fibres tested shall be representative of the cable design and shall be agreed between the customer and the supplier.

Câbles à fibres optiques - Partie 3-20: Câbles extérieurs - Spécification de famille pour les câbles de télécommunication aériens autoporteurs (CEI 60794-3-20:2009)

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 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.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60794-3-20 has been prepared by Subcommittee 86A: Fibres and
cables, of IEC Technical Committee 86: Fibre optics.
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.

OPTICAL FIBRE CABLES –

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



1 Scope
This part of IEC 60794 which is a family specification 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.
Self-supporting aerial telecommunication cable in this context means a cable construction
with sufficient strength members designed to be suspended on poles and similar devices
without the aid of another supporting wire or conductor. ADSS cables and other constructions
intended for high-voltage applications are not covered by this standard.
Detail specifications may be prepared based on this family specification.
Clause A.2 contains requirements that supersede the normal requirements in case the cables
are intended to be used in installation governed by the MICE table of ISO/IEC 24702.
The parameters specified in this standard may be affected by measurement uncertainty
arising either from measurement errors or calibration errors due to lack of suitable standards.
Acceptance criteria shall be interpreted with respect to this consideration (see IEC 60794-3,
Clause 8).
The number of fibres tested shall be representative of the cable design and shall be agreed
between the customer and the supplier.
