IEC 60794-6:2020

Optical fibre cables - Part 6: Indoor-outdoor cables - Sectional specification for indoor-outdoor cables

IEC 60794-6:2020 is a sectional specification covering general features of optical fibre cables applicable to outdoor as well as indoor environments, called "indoor-outdoor cables". Indoor-outdoor cables are deployed in outside plant environments as well as in premises thus fulfilling outdoor as well as indoor requirements. Typical application spaces are, for example, extension of a duct cable into a building or using this design for centralized cabling in the central office, the premises or local area network where the same cable is used for the entire length of the cabling link including both the indoor as well as the outdoor portions. Cables which generally possess the characteristics associated with outdoor cable designs having the thermal and mechanical robustness that makes them suitable for use in the outside plant, while simultaneously being relatively flexible, compact and lightweight and exhibiting the fire performance required in indoor premises are specified in IEC 60794-6-10. Flame retardant outdoor cables as specified in IEC 60794-6-20 are used when most of the cable length is deployed as an outdoor cable with a part of its length deployed indoors. The cable design can be derived from a typical outdoor cable design according to the product specifications described in IEC 60794-3. The specific performance related to bend radii according to the installation situation and fire performance according to the regional legislation mainly requires the appropriate selection of the jacket material in combination with other material and/or design considerations. Because of the use in buildings with tighter space restrictions, higher flexibility of the cable is often required for the installation. Often, smaller diameter cables are preferred. Indoor cables which are weatherised as specified in (IEC 60794-6-30) are used when an indoor cable is used outdoors over a short distance (few meters), for example when the network access point (NAP) is very close to the building. The indoor-outdoor fibre optical cable design can be derived from an indoor design (see IEC 60794-2 and IEC TR 62901 for typical applications) with specific outdoor performance features added. Critical parameters are UV stability, and resistance against exposure to humidity.

Câbles à fibres optiques - Partie 6: Câbles intérieurs/extérieurs - Spécification intermédiaire pour les câbles intérieurs/extérieurs

IEC 60794-6:2020 est une spécification intermédiaire qui couvre les fonctionnalités générales des câbles à fibres optiques destinés aussi bien aux environnements extérieurs qu'aux environnements intérieurs, ci-après désignés "câbles intérieurs/extérieurs". Les câbles intérieurs/extérieurs sont déployés dans les environnements d'usine extérieurs ainsi que dans les locaux, satisfaisant donc aux exigences d'utilisation en extérieur ainsi qu'aux exigences d'utilisation en intérieur. Les applications types sont par exemple: prolongation dans un bâtiment d'un câble installé dans un conduit, ou utilisation de cette conception pour réaliser un câblage centralisé dans le bureau central, les locaux ou le réseau local exploitant le même câble sur toute la longueur des liaisons de câblage, englobant les portions en intérieur ainsi que les portions en extérieur. Les câbles qui possèdent généralement les caractéristiques associées à des conceptions de câbles extérieurs, présentant la robustesse thermique et mécanique qui les rend appropriés pour une utilisation dans les environnements d'usine extérieurs, tout en restant relativement souples, compacts et légers et en présentant le comportement au feu exigé à l'intérieur des locaux, sont spécifiés dans l'IEC 60794-6-10. Les câbles extérieurs retardateurs de flamme spécifiés dans l'IEC 60794-6-20 sont utilisés lorsque la majeure partie de la longueur de câble est déployée dans un environnement extérieur, et que la portion restante est déployée dans un environnement intérieur. La conception de câble peut être déterminée à partir d'une conception de câble extérieur type, conformément aux spécifications de produit décrites dans l'IEC 60794-3. Les performances spécifiques relatives aux rayons de courbure, conformément à la situation d'installation et au comportement au feu, et conformément à la législation régionale en vigueur, exigent principalement de choisir de manière appropriée le matériau de la gaine, ainsi que son association à d'autres matériaux et/ou à d'autres considérations relatives à la conception. En raison d'une utilisation dans des bâtiments qui présentent des restrictions liées à des espaces plus confinés, une plus grande souplesse du câble est souvent exigée pour l'installation. Souvent, des câbles de diamètre réduit sont privilégiés.
Des câbles intérieurs qui sont conçus pour être résistants aux intempéries, spécifiés dans l'IEC 60794-6-30, sont utilisés lorsqu'un câble intérieur est utilisé en extérieur sur une courte distance (quelques mètres), par exemple lorsque le point d'accès au réseau (NAP, network access point) est très proche du bâtiment. La conception de câble à fibres optiques intérieur/extérieur peut être déterminée à partir d'une conception de câble intérieur (voir l'IEC 60794-2 et l'IEC TR 62901 pour des applications types), en y ajoutant des fonctionnalités spécifiques de comportement en extérieur. Les paramètres critiques sont la stabilité au rayonnement ultraviolet (UV) et la résistance à l'exposition à l'humidité.

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.
