Fibre management systems and protective housings to be used in optical fibre communication systems - Product specifications - Part 2-4: Sealed dome fibre splice closures for category S & A

1.1 Product definition This document contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements of a fully installed splice closure in order for it to be categorized as a European Standard product. 1.2 Operating environment The tests selected combined with the severity and duration are representative of an outside plant for subterranean and/or aerial environments defined by: EN IEC 61753 1 category S: subterranean environment category A: aerial environment 1.3 Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this specification does not guarantee the reliability of the product. This is predicted using a recognized reliability assessment programme. 1.4 Quality assurance Compliance with this specification does not guarantee the manufacturing consistency of the product. This is maintained using a recognized quality assurance programme. 1.5 Allowed fibre and cable types This closure standard allows both single-mode and multi-mode fibre to be used and covers all IEC standard optical fibre cables with their various fibre capacities, types and designs. This includes, but is not limited to, optical fibre cable standards EN 60794 2 (indoor) and EN 60794 3 (outdoor). The optical performance tests are carried out on test samples with EN IEC 60793 2 50 single-mode fibre (see Annex A). The selected fibre type for the optical test samples depends on the design of the fibre management system.

1.1 Produktdefinition Dieses Dokument enthält die Anfangs- und Maßanforderungen zu Beginn der Lebensdauer sowie die optischen, mechanischen und umweltbezogenen Betriebsverhaltensanforderungen an eine vollständig installierte Spleißmuffe, damit sie als ein europäisches Normprodukt eingestuft werden kann. 1.2 Betriebsumgebung Die ausgewählten Prüfungen in Kombination mit der Prüfschärfe und der Dauer sind repräsentativ für eine Außenanlage mit unterirdischer und/oder Luftumgebungen, die definiert sind in: EN IEC 61753-1:2018 Kategorie S: unterirdische Umgebung Kategorie A: Umgebung in Luft 1.3 Zuverlässigkeit Die erwartete Betriebslebensdauer des Produkts in dieser Umgebung beträgt 20 Jahre, wobei die Einhaltung dieser Norm die Zuverlässigkeit des Produktes nicht sichergestellt. Diese sollte unter Verwendung eines anerkannten Programms zur Bewertung der Zuverlässigkeit vorausgesagt werden. 1.4 Qualitätssicherung Die Einhaltung dieser Norm stellt nicht die Gleichmäßigkeit bei der Fertigung des Produktes sicher. Diese sollte unter Verwendung eines anerkannten Qualitätssicherungsprogramms aufrechterhalten werden. 1.5 Zulässige Faser- und Kabeltypen Obwohl die Prüfungen der Gebrauchseigenschaften an Prüflingen mit nicht dispersionsverschobener Faser nach EN 60793-2-50, B1.3 (siehe Anhang A) durchgeführt wird, ist die einmal nach dieser europäischen Norm geprüfte Muffe auch für andere Fasertypen geeignet, z. B. für nulldispersionsverschobene, nichtnulldispersionsverschobene sowie für Mehrmodenfasern. Diese Muffennorm ermöglicht sowohl die Verwendung von Einmoden- als auch Mehrmoden-Lichtwellenleitern und deckt die Lichtwellenleiterkabel aller IEC-Normen mit ihren unterschiedlichen LWL-Aufnahmekapazitäten, Kabeltypen und -Ausführungen ab. Dies schließt unter anderem die Normen für LWL-Kabel EN 60794-2 (Innenkabel) und EN 60794-3 (Außenkabel) ein.

1.1 Définition du produit Le présent document contient les exigences de performances initiales, de début de vie, dimensionnelles, optiques, mécaniques et environnementales d’un boîtier à épissure entièrement installé, afin d’être classé comme produit couvert par une Norme européenne. 1.2 Environnement de fonctionnement Les essais choisis, combinés avec les sévérités et les durées, sont représentatifs d’une installation extérieure pour les environnements souterrains et/ou aériens définis par les normes suivantes: EN IEC 61753 1 catégorie S: environnement souterrain catégorie A: environnement aérien 1.3 Fiabilité Bien que l’espérance de vie en service prévue du produit dans cet environnement soit de 20 ans, la conformité à cette spécification ne garantit pas la fiabilité du produit. Celle-ci est estimée en utilisant un programme reconnu d’évaluation de la fiabilité. 1.4 Assurance de la qualité La conformité à la présente spécification ne garantit pas la cohérence de fabrication du produit. Elle est maintenue en utilisant un programme reconnu d’assurance qualité. 1.5 Types de fibres et câbles autorisés La présente norme de boîtier permet d’utiliser tant la fibre unimodale que la fibre multimodale et couvre tous les câbles à fibres optiques des normes IEC avec leurs différents types, capacités et conceptions de fibres. Cela inclut notamment les normes de câbles à fibres optiques EN 60794 2 (intérieurs), EN 60794 3 (extérieurs). Les essais de performance optique sont effectués sur des échantillons d’essais avec des fibres unimodales selon l’EN IEC 60793 2 50 (voir Annexe A). Le type de fibre choisi pour les échantillons d’essais optiques dépend de la conception du système de gestion des fibres.
