Optical fibre cables - Part 5-20: Family specification for outdoor microduct fibre units, microducts and protected microducts for installation by blowing

EN IEC 60794-5-20 is a family specification that covers outdoor microduct fibre units and corresponding microducts and protected microducts for installation by blowing. The protected microducts are intended for duct, directly buried or lashed applications. Microduct fibre units differ from microduct optical fibre cables (see IEC 60794-5-10) in that they provide less protection to the fibres that they contain. Specifically, microduct fibre units rely on the structure of the microduct, protected microduct or appropriate housing to support installation and to provide additional mechanical protection for the optical fibre over the lifetime of the product. Systems built with components covered by this standard are subject to the requirements of sectional specification IEC 60794-5 where applicable. Annex A gives examples of microduct optical fibre units and microducts. Annex B describes a blank detail specification for outdoor microduct fibre units 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 product constructions for microduct optical fibre units, microducts and protected microducts. 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 tested is intended to be representative of the microduct fibre unit design and should be agreed between the customer and supplier.

IEC 60794-5-20:2014 est une spécification de famille qui couvre les éléments fibres en microconduit extérieur, ainsi que les microconduits et microconduits protégés correspondants pour installation par soufflage. Les microconduits protégés sont destinés à des applications de conduits, d'enfouissement direct ou de câbles lacés.   Les éléments fibres en microconduit se différencient des câbles à fibres optiques en microconduit (voir l'IEC 60794-5-10) par une protection moindre des fibres contenues. De manière spécifique, les éléments fibres en microconduit reposent sur la structure du microconduit, du microconduit protégé ou du logement approprié pour supporter leur installation et pour fournir une protection mécanique supplémentaire à la fibre optique pendant la durée de vie du produit. Les systèmes intégrant des éléments couverts par la présente norme sont soumis aux exigences de la spécification intermédiaire IEC 60794-5, le cas échéant.

Optični kabli - 5-20. del: Skupinska specifikacija za mikrokanale za zunanjo uporabo za optične enote, mikrokanale in zaščitene mikrokanale za vgradnjo z vpihovanjem (IEC 60794-5-20:2014)

Standard EN IEC 60794-5-20 je skupinska specifikacija, ki zajema mikrokanale za zunanjo uporabo za optične enote, ustrezne mikrokanale in zaščitene mikrokanale za vgradnjo z vpihovanjem. Zaščiteni mikrokanali so namenjeni vgradnji v kanale, podzemeljske ali povezane naprave. Mikrokanali za optične enote se razlikujejo od mikrokanalov optičnih kablov (glejte IEC 60794-5-10) v tem, da vlaknom, ki jih vsebujejo, zagotavljajo manj zaščite. Predvsem so mikrokanali pri zagotavljanju dodatne mehanske zaščite optičnim vlaknom med življenjsko dobo izdelka odvisni od sestave mikrokanala, zaščitenega mikrokanala ali ustreznega ohišja, ki podpira namestitev. Za sisteme, zgrajene s komponentami, ki so zajete v tem standardu, veljajo zahteve področne specifikacije IEC 60794-5, kjer je to primerno. Dodatek A navaja primere mikrokanalov za optične enote za uporabo na prostem in mikrokanalov. Dodatek B opisuje okvirno podrobno specifikacijo za mikrokanale za optične enote za uporabo na prostem in povezane mikrokanale ter podaja nekatere minimalne zahteve. Podrobna specifikacija izdelka se lahko pripravi na osnovi te skupinske specifikacije z uporabo dodatka B kot vodnika. Dodatek C podaja normativne konstrukcije izdelka za mikrokanale za optične enote, mikrokanale in zaščitene mikrokanale. Na parametre, navedene v tem standardu, lahko vpliva merilna negotovost, ki se pojavi zaradi merilnih napak ali napak umerjanja zaradi pomanjkanja ustreznih standardov. Kriterije sprejemljivosti naj bi obravnavali ob upoštevanju teh pomislekov. Število preskušenih vlaken mora biti reprezentativno za načrtovanje mikrokanalov za optične enote, o čemer naj bi se dogovorila stranka in dobavitelj.

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 5-20: Family specification –
Outdoor microduct fibre units, microducts and
protected microducts for installation by blowing



1 Scope
This part of IEC 60794 is a family specification that covers outdoor microduct fibre units and
corresponding microducts and protected microducts for installation by blowing. The protected
microducts are intended for duct, directly buried or lashed applications.
Microduct fibre units differ from microduct optical fibre cables (see IEC 60794-5-10) in that
they provide less protection to the fibres that they contain. Specifically, microduct fibre units
rely on the structure of the microduct, protected microduct or appropriate housing to support
installation and to provide additional mechanical protection for the optical fibre over the
lifetime of the product.
Systems built with components covered by this standard are subject to the requirements of
sectional specification IEC 60794-5 where applicable.
Annex A gives examples of microduct optical fibre units and microducts.
Annex B describes a blank detail specification for outdoor microduct fibre units 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 product constructions for microduct optical fibre units,
microducts and protected microducts.
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 tested is intended to be representative of the microduct fibre unit design
and should be agreed between the customer and supplier.
