Optical fibre cables - Part 3: Sectional specification - Outdoor cables
IEC 60794-3:2014 specifies the requirements for optical fibre cables and cable elements which are intended to be used externally in communications networks. Other types of applications requiring similar types of cables can be considered. Requirements for cables to be used in ducts, for directly buried applications, aerial cables and cables for lake and river crossings are included in this standard. Also included are cables for specialized use in sewers and in water and gas pipes. For aerial application, this standard does not cover all functional aspects of cables installed in the vicinity of overhead power lines. For such applications, additional requirements and test methods may be necessary. Moreover, this standard excludes optical ground wires and cables attached to the phase or earth conductors of overhead power lines. For cables for lake and river crossings, this standard does not cover methods of cable repair, nor repair capability, nor does it cover cables for use with underwater line amplifiers. This fourth edition cancels and replaces the third edition, published in 2001, and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - the specification has been streamlined by cross-referencing with IEC 60794-1-1; - soft strippable tubes introduced into the "polymeric" tube heading and metal tubes have been added; - ribbon clauses have been simplified; - more precise outer sheath details have been added; - cable element tests and cable tests have been simplified by the use of tables instead of text; - Annex A on PMD has been removed, to avoid duplication with IEC TR 61282-3. Keywords: outdoor cables, requirements for optical fibre cables and cable elements

Câbles à fibres optiques - Partie 3: Câbles extérieurs - Spécification intermédiaire
L'IEC 60794-3:2014 spécifie les exigences relatives aux câbles et aux éléments de câble à fibres optiques destinés à être utilisés à l'extérieur dans des réseaux de télécommunication. D'autres types d'applications nécessitant des câbles d'un type similaire peuvent être envisagés. La présente norme comporte des exigences concernant les câbles destinés à être installés dans des conduites, les câbles directement enterrés, les câbles aériens et les câbles pour traversées de lacs et de rivières. Elle comporte également des câbles destinés à des utilisations spécialisées, dans les égouts et dans les conduites d'eau et de gaz. Pour ce qui est des applications aériennes, la présente norme ne couvre pas tous les aspects fonctionnels des câbles installés à proximité de lignes aériennes de transport d'énergie. De telles applications peuvent nécessiter l'adjonction d'exigences et de méthodes d'essai. En outre, la présente norme exclut les câbles de garde avec fibres optiques et les câbles liés aux conducteurs de phase ou de terre des lignes aériennes de transport d'énergie. Pour les câbles pour traversées de lacs et de rivières, la présente norme ne couvre pas les méthodes de réparation du câble, ni de capacité de réparation, et ne couvre pas les câbles utilisés dans les amplificateurs de lignes pour traversées de lacs et de rivières. Cette quatrième édition annule et remplace la troisième édition, parue en 2001, dont elle constitue une révision technique. Cette édition contient les modifications techniques majeures suivantes par rapport à l'édition précédente: - la spécification a été simplifiée en introduisant des références croisées avec l'IEC 60794-1-1; - des tubes souples dénudables introduits en tête de tubes polymères et des tubes métalliques ont été ajoutés; - les articles relatifs aux rubans ont été simplifiés; - des informations plus précises sur les gaines extérieures ont été ajoutées; - les essais sur les éléments de câble et les essais sur les câbles ont été simplifiés en remplaçant le texte par des tableaux; - l'Annexe A sur la PMD a été retirée pour éviter une redondance avec l'IEC TR 61282-3. Mots clés: câbles extérieurs, exigences relatives aux câbles et aux éléments de câble à fibres optiques
