IEC 60794-2-30:2019

Optical fibre cables - Part 2-30: Indoor cables - Family specification for optical fibre ribbon cables for use in terminated cable assemblies

IEC 60794-2-30:2019 is a family specification which covers indoor optical fibre ribbon cables for use in terminated cable assemblies. The requirements of the sectional specification IEC 60794-2 are applicable to cables covered by this document. The requirements of this document are written to define flat ribbon cables. This document can be applicable to other cable constructions. Parts of IEC 60794-3 which are applicable for ribbon tests are the subject of IEC 60794-1-31. Annex B 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 11801-3.This third edition cancels and replaces the second edition published in 2008. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:
a) removal of Annex C;
b) reference to the most recent fibre standards;
c) reference to IEC 60794-1-21, IEC 60794-1-22, IEC 60794-1-23 and IEC 60794-1-24.
This standard is to be used in conjunction with IEC 60794-1-1, IEC 60794-1-2 and
IEC 60794-2.
Keywords: indoor optical fibre ribbon cables, flat ribbon cables

Câbles à fibres optiques - Partie 2-30: Câbles intérieurs - Spécification de famille pour les câbles à rubans de fibres optiques utilisés dans les assemblages de câbles connectorisés

IEC 60794-2-30:2019 est une spécification de famille qui couvre les câbles à rubans de fibres optiques intérieurs pour usage dans les assemblages de câbles connectorisés. Les exigences de la spécification intermédiaire IEC 60794-2 sont applicables aux câbles couverts par le présent document. Les exigences présent document sont écrites pour définir un câble à ruban plat. Le présent document peut être applicable à d’autres constructions de câbles. Les parties de l’IEC 60794-3 qui sont applicables pour les essais de rubans constituent le sujet de l’IEC 60794-1-31. L’Annexe B 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 11801-3. Cette troisième édition annule et remplace la deuxième édition parue en 2008. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:
a) retrait de l’Annexe C;
b) référence aux normes les plus récentes relatives aux fibres;
c) référence à l'IEC 60794-1-21, l'IEC 60794-1-22, l'IEC 60794-1-23 et l'IEC 60794-1-24.
La présente norme doit être utilisée conjointement avec l’IEC 60794-1-1, l’IEC 60794-1-2 et l’IEC 60794-2.

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
