Optical fibre cables - Part 6-10: Indoor-outdoor cables - Family specification for universal indoor-outdoor cables

IEC 60794-6-10:2020 is a family specification covering features of optical fibre cables applicable to outdoor as well as indoor environments, called "universal indoor-outdoor cables". These cables generally possess the characteristics associated with outdoor cable designs (according to IEC 60794-3, however typically less stringent, and typically "non armoured") having the thermal and mechanical robustness that makes them suitable for use in the outside plant, while simultaneously being flexible enough, compact and lightweight and exhibiting the fire performance required in indoor premises. A typical application is for example the centralized cabling in central office and the premises or local area network where the same cable design is used for the entire length of the cabling link including both the indoor as well as the outdoor portions.

Câbles à fibres optiques - Partie 6-10 : Câbles intérieurs/extérieurs - Spécification de famille pour les câbles intérieurs/extérieurs universels

IEC 60794-6-10:2020 est une spécification de famille qui couvre les fonctionnalités des câbles à fibres optiques destinés aussi bien aux environnements extérieurs qu'aux environnements intérieurs, ci-après désignés "câbles intérieurs/extérieurs universels". Ces câbles possèdent généralement les caractéristiques associées à des conceptions de câbles extérieurs (conformément à l'IEC 60794-3, appliquée cependant habituellement de manière moins rigoureuse, et en général "non armés"), présentant la robustesse thermique et mécanique qui les rend appropriés pour une utilisation dans les environnements d'usine extérieurs, tout en restant suffisamment souples, compacts et légers, et en présentant le comportement au feu exigé à l'intérieur des locaux. Une application type est par exemple la réalisation d'un câblage centralisé dans le bureau central et les locaux ou le réseau local exploitant la même conception de câble sur toute la longueur des liaisons de câblage, englobant les portions en intérieur ainsi que les portions en extérieur.

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
