Optical fibre cables - Part 5-10: Family specification - Outdoor microduct optical fibre cables, microducts and protected microducts for installation by blowing

IEC 60794-5-10:2014 is a family specification that covers outdoor microduct optical fibre cables for installation by blowing and the associated microducts, which together make up a microduct optical fibre cable system. Although primarily designed for use with outdoor microduct applications, the cable products specified herein may be used individually for short lengths in other applications as agreed upon between supplier and customer. These may include short runs inside a building or in other outdoor applications, such as a transition between separate (unconnected) microduct systems, or from a microduct system to some other protective structure such as a cable conduit or tray. Systems built with components covered by this standard are subject to the requirements of IEC 60794-5 where applicable. Keywords: outdoor microduct optical fibre cables, installation by blowing

Câbles à fibres optiques - Partie 5-10: Spécification de famille - Câbles extérieurs à fibres optiques en micro-conduit, micro-conduits et micro-conduits protégés pour installation par soufflage

IEC 60794-5-10:2014 est une spécification de famille qui couvre les câbles extérieurs à fibres optiques en micro-conduit destinés à être installés par soufflage, et les micro-conduits associés, constituant ensemble un système de câbles à fibres optiques en micro-conduit. Bien qu'ils soient principalement conçus pour être utilisés avec des applications pour micro-conduit extérieur, les produits câbles ici spécifiés peuvent être utilisés individuellement sur de courtes longueurs dans d'autres applications, après accord entre le fournisseur et le client. Ceux-ci peuvent inclure de courtes longueurs à l'intérieur d'un bâtiment ou dans d'autres applications à l'extérieur, telles qu'une transition entre des systèmes de micro-conduits séparés (non connectés), ou un système de micro-conduit vers une autre structure protectrice telle qu'un conduit ou un chemin de câble. Les systèmes intégrant des éléments couverts par la présente norme sont soumis aux exigences de l'IEC 60794-5, le cas échéant. Mots clés: câbles extérieurs à fibres optiques en micro-conduit, installés par soufflage

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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

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.

OPTICAL FIBRE CABLES –
Part 5-10: Family specification –
Outdoor microduct optical fibre cables, microducts and protected
microducts for installation by blowing
1 Scope

This part of IEC 60794 is a family specification that covers outdoor microduct optical fibre

cables for installation by blowing and the associated microducts, which together make up a

microduct optical fibre cable system. Although primarily designed for use with outdoor

microduct applications, the cable products specified herein may be used individually for short

lengths in other applications as agreed upon between supplier and customer. These may

include short runs inside a building or in other outdoor applications, such as a transition

between separate (unconnected) microduct systems, or from a microduct system to some

other protective structure such as a cable conduit or tray.

Systems built with components covered by this standard are subject to the requirements of

IEC 60794-5 where applicable.

Annex A shows examples of microduct optical fibre cables and microducts. Annex B describes

a blank detail specification for outdoor microduct optical fibre cables and the associated

microducts, and incorporates some minimum requirements. Detail product specifications may

be prepared on the basis of this family specification using Annex B as a guide. Annex C

provides normative requirements for microduct optical fibre cables.

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 should be interpreted with respect to this consideration.

The number of fibres and microducts tested shall be representative of the microduct optical

fibre cable design and should be agreed between customer and supplier.
