Fibre management systems and protective housings to be used in optical fibre communication systems - Product specifications - Part 3-1: Wall or pole mounted box for splices, for category C and A
1.1 Product definition This document contains the dimensional, optical, mechanical and environmental performance requirements of a fully installed optical fibre wall or pole mounted box for up to 288 fibre splices, in order for it to be categorized as a European standard product. The typical configuration is splicing of incoming fibres to optional splitters, connecting on the other side to outgoing fibres. A box is a protective housing containing a fibre management system with splice trays of various fibre separation levels. The box can contain one or more of the following: - storage and routing for fibre and cable; - uncut fibre cable storage; - splice trays; - passive optical devices (optical splitters or WDM). A box can be installed on a vertical indoor or outdoor surface above ground level. If the box is required to be relocatable with cables attached, the following additional tests are expected to be performed: - cable bending; - cable torsion. This document specifies the number of splice trays and splice capacity for each fibre separation level. The maximum capacity is 288 splices. For housings with a higher number of splices, EN 50411 4 1 (street cabinets) can be used. Boxes for fibre splice and patchcord connections are covered in EN 50411 3 4. 1.2 Operating environment The tests selected, combined with the severity and duration, are representative of indoor and outside plant for above ground environments defined by EN IEC 61753 1: - category C: Controlled (indoor) environment; - category A: Aerial (outdoor above ground) environment. 1.3 Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this document does not guarantee the reliability of the product. This is expected to be predicted using a recognized reliability assessment programme. 1.4 Quality assurance Compliance with this document does not guarantee the manufacturing consistency of the product. This is expected to be maintained using a recognized quality assurance programme. 1.5 Allowed fibre and cable types This box standard accommodates EN IEC 60793 2 50 single-mode fibres and EN IEC 60793 2 10 A1-OM2 to A1-OM5 and A1-OM1 multimode fibres and all EN 60794 series optical fibre cables with various fibre capacities, types and designs.

1.1 Définition du produit Le présent document contient les exigences de performance dimensionnelles, optiques, mécaniques et environnementales d’une boîte de fibres optiques murale ou montée sur poteau, entièrement installée, capable d’accueillir jusqu’à 288 épissures de fibres, ces exigences lui permettant d’être catégorisée comme produit à la norme européenne. La configuration type comprend l’épissurage de fibres entrantes sur des répartiteurs facultatifs, raccordées de l’autre côté sur des fibres sortantes. Une boîte est un coffret de protection contenant un système de gestion de fibres équipé de plateaux d’épissures offrant différents niveaux de séparation de fibres. La boîte peut offrir une ou plusieurs des fonctions suivantes: - stockage et acheminement pour les fibres et les câbles; - stockage de câble de fibres non découpées; - plateaux d’épissures; - dispositifs optiques passifs (répartiteurs optiques ou WDM). Une boîte peut être installée sur une surface intérieure ou extérieure verticale, au-dessus du niveau du sol. S’il est exigé que la boîte puisse être déplacée avec ses câbles déjà fixés, les essais supplémentaires suivants sont censés être effectués: - courbure de câble; - torsion de câble. Le présent document spécifie le nombre de plateaux d’épissures et la capacité en épissures pour chaque niveau de séparation de fibres. La capacité maximale est de 288 épissures. Pour les coffrets contenant davantage d’épissures, l’EN 50411-4-1 (baies urbaines) peut être utilisée. Les boîtes destinées aux raccordements d’épissures de fibres et de cordons de brassage sont traitées dans l’EN 50411-3-4. 1.2 Environnement de fonctionnement Les essais sélectionnés, combinés aux sévérités et aux durées, sont représentatifs d’une installation intérieure et extérieure au-dessus du niveau du sol définie par l’EN IEC 61753-1: - catégorie C: Environnement contrôlé (intérieur); - catégorie A: Environnement aérien (extérieur au-dessus du niveau du sol). 1.3 Fiabilité Tandis que l’espérance de vie du produit en service prévue dans cet environnement est de 20 ans, la conformité au présent document ne garantit pas la fiabilité du produit. Il est attendu que celle-ci soit estimée en utilisant un programme reconnu d’évaluation de la fiabilité. 1.4 Assurance de la qualité La conformité au présent document ne garantit pas la cohérence de fabrication du produit. Il est attendu qu’elle soit suivie au moyen d’un programme reconnu d’assurance de la qualité. 1.5 Types de fibres et câbles autorisés La présente norme concernant les boîtes contient l’EN IEC 60793-2-50 sur les fibres unimodales et l’EN IEC 60793-2-10 A1-OM2 à A1-OM5 et A1-OM1 sur les fibres multimodales et toute la série EN 60794 sur les câbles à fibres optiques avec différentes capacités de fibre, différents types et différentes conceptions.
