Fibre organisers and closures to be used in optical fibre communication systems - Product specifications - Part 2-4: Sealed dome fibre splice closures Type 1, for category S & A
1.1 Product definition This specification 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 categorised as an EN 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: ETS 300 019 class 8.1: underground locations (without earthquake requirement) 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 should be predicted using a recognised reliability assessment programme. 1.4 Quality assurance Compliance with this specification does not guarantee the manufacturing consistency of the product. This should be maintained using a recognised quality assurance programme. 1.5 Allowed fibre and cable types Although the performance tests are carried out on test samples with dispersion unshifted single mode fibre (see Annex A), the closure, once tested according to this product specification, will be also suited for other fibre types like dispersion shifted, non-zero dispersion shifted and multi-mode fibres. This closure standard allows both singlemode and multimode 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), EN 60794-3 (outdoor).

1.1 Définition de produit La présente spécification contient les exigences de performances initiales, dimensionnelles, de début de vie, optiques, mécaniques et environnementales d’un boîtier à épissure entièrement installé, afin d'être classé comme produit couvert par une norme EN de produit. 1.2 Environnement de fonctionnement Les essais sélectionnés, 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: ETS 300 019 classe 8.1: emplacements souterrains (sans exigence sismique) CEI 61753-1 catégorie S: environnement souterrain - catégorie A: environnement aérien 1.3 Fiabilité Tandis que l'espérance de vie en service prévue du produit dans cet environnement est de 20 ans, la conformité avec cette spécification ne garantit pas la fiabilité du produit. Il convient que celle-ci soit estimée en utilisant un programme reconnu d'évaluation de la fiabilité. 1.4 Assurance de la qualité La conformité à cette spécification ne garantit pas la cohérence de fabrication du produit. Il convient qu’elle soit maintenue en utilisant un programme d'assurance de la qualité reconnu. 1.5 Types de fibres et câbles autorisés Bien que les essais de performance soient effectués sur des échantillons d’essai avec des fibres monomodales à gaines compensées avec dispersion non décalée (voir Annexe A), le boîtier, une fois essayé conformément à cette spécification de produit, sera également adapté à d’autres types de fibres tels que les fibres à dispersion décalée, à dispersion non-nulle décalée et multimodales. La norme de boîtier permet tant à la fibre monomodale qu’à la fibre multimodale d’être utilisée et couvre tous les câbles à fibres optiques des normes CEI avec leurs diverses capacités, types et conceptions de fibres. Ceci inclut les, mais ne limite pas aux, normes de câbles à fibres optiques EN 60794-2 (intérieurs), EN 60794-3 (extérieurs).

1 Scope
1.1 Product definition
This specification 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 categorised as an EN
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:
ETS 300 019 class 8.1: underground locations (without earthquake requirement)
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 should be predicted using a
recognised reliability assessment programme.
1.4 Quality assurance
Compliance with this specification does not guarantee the manufacturing consistency of the product. This
should be maintained using a recognised quality assurance programme.
1.5 Allowed fibre and cable types
Although the performance tests are carried out on test samples with dispersion unshifted single mode fibre
(see Annex A), the closure, once tested according to this product specification, will be also suited for other
fibre types like dispersion shifted, non-zero dispersion shifted and multi-mode fibres.
This closure standard allows both singlemode and multimode 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), EN 60794-3 (outdoor).
