Fibre management systems and protective housings to be used in optical fibre communication systems - Product specifications - Part 3-2: Single-mode mechanical fibre splice
1.1 Product definition This document contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements, which single mode mechanical splice needs to meet in order for it to be categorized as a European standard product. Although, in this document, the product is qualified for EN IEC 60793 2 50 type B-652.D single mode fibres, it is also suitable for mechanical splicing of other single mode fibres with 125 µm diameter glass cladding. Also mechanical splices designed for connections of buffered or secondary coated fibres and cords according to EN 60794 2 50:2008 are covered by this document. 1.2 Interoperability The installed mechanical splice fits into optical fibre management system with optical splice cassettes or splice trays as defined in EN IEC 61756 1. This document specifies the following two physical interface dimensions: - cross sectional profile with width, height or diameter (in millimetres); - length (in millimetres). 1.3 Expected performance In this document, the performance of the mechanical splice is given with identical fibres only as specified in Annex A. Losses associated with tolerances in fibre cladding diameter and mode field mismatch are not taken into account. The measured attenuation is a function of the core concentricity, cladding non-circularity and alignment capability. The optical return loss performance is a function of the index matching gel and the fibre end face preparation. 1.4 Operating environment The tests selected combined with the severities and durations are representative of an outdoor enclosed environment defined as category OP in EN IEC 61753 1. To ensure that the product can be used in outdoor closures, boxes or street cabinets for categories A, G or S (as defined in EN IEC 61753 1) the specified lower temperature is extended to −40 °C and a water immersion requirement for temporary flooding conditions has been added. 1.5 Reliability Whilst the anticipated service life expectancy of the product in this environment is at least 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. 1.6 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.

Systèmes de gestion des fibres et boîtiers de protection destinés à être utilisés dans les systèmes de communication par fibres optiques - Spécifications de produit - Partie 3-2: Épissures mécaniques de fibres unimodales
1.1 Définition du produit Le présent document contient les exigences de performances initiales, dimensionnelles, optiques, mécaniques et environnementales, de début de vie, auxquelles une épissure mécanique unimodale est tenue de satisfaire, afin d’être classée comme produit conforme à une norme EN. Bien que, dans le présent document, le produit soit qualifié pour des fibres unimodales de type B-652.D de l’EN IEC 60793 2 50, il peut également convenir à l’épissurage mécanique d’autres fibres unimodales de diamètre de gaine de verre 125 µm. 1.2 Interopérabilité Les épissures mécaniques installées s’adaptent à un système de gestion de fibres optiques avec des cassettes ou des plateaux d’épissures de fibres optiques tels que définis dans l’EN IEC 61756 1. Le présent document spécifie les deux dimensions d’interface physique suivantes: — profil transversal avec largeur, hauteur ou diamètre (en millimètres); — longueur (en millimètres). 1.3 Performance attendue Dans le présent document, la performance d’une épissure mécanique est donnée uniquement avec des fibres identiques, comme spécifiée dans l’Annexe A. Les pertes associées aux tolérances sur le diamètre de la gaine de fibre et le défaut d’adaptation du champ de mode ne sont pas prises en compte. L’affaiblissement mesuré dépend de la concentricité du cœur, de la non-circularité de la gaine et de la capacité d’alignement. La performance de l’affaiblissement de réflexion optique dépend du gel permettant de conserver l’indice et de la préparation de l’extrémité de la fibre 1.4 Environnement de fonctionnement Les essais choisis, combinés avec les sévérités et les durées, sont représentatifs de l’environnement extérieur enfermé défini comme catégorie OP dans l’EN IEC 61753 1. Afin d’assurer que le produit puisse être utilisé dans des boîtiers extérieurs, des boîtes ou des armoires d’environnement urbain pour les catégories A, G et S (telles que définies dans l’EN IEC 61753 1), la température inférieure spécifiée est étendue à -40 °C, et des exigences relatives à l’immersion dans l’eau en cas d’inondation temporaire ont été ajoutées. 1.5 Fiabilité Tandis que l’espérance de vie du produit en service prévue dans cet environnement est d’au moins 20 ans, la conformité à la présente spécification 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. 1.6 Assurance de la qualité La conformité à la présente spécification 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.
Sistemi za upravljanje z optičnimi vlakni in zaščitna ohišja za optične komunikacijske sisteme - Specifikacije izdelka - 3-2. del: Enorodovna mehanska optična spojnica
Ta dokument vsebuje začetne dimenzijske, optične, mehanske in okoljske zahteve, ki jih mora na začetku svoje življenjske dobe izpolnjevati enorodna mehanska spojnica, da se lahko kategorizira kot izdelek v skladu z evropskim standardom.
Čeprav je v tem dokumentu izdelek kvalificiran za enorodovna vlakna po standardu EN 60793 2 50 kategorije B-652.D, je lahko prav tako ustrezen za mehansko spajanje drugih enorodovnih vlaken s steklenim plaščem debeline 125 μm.
1.2 Interoperabilnost
Vgrajena mehanska spojnica se prilega sistemu za upravljanje optičnih vlaken s kasetami ali pladnji s spojnicami, kot je opredeljeno v standardu EN IEC 61756 1. Ta dokument določa naslednji dve dimenziji fizičnega vmesnika:
– prečni profil s širino, višino ali premerom (v milimetrih);
– dolžino (v milimetrih).
1.3 Pričakovana zmogljivost
V tem dokumentu je zmogljivost mehanske spojnice podana samo z enakimi vlakni, kot je določeno v dodatku A. Izgube, povezane s tolerancami premera oplaščenih vlaken in neusklajenostjo polja načina, se ne upoštevajo. Izmerjeno slabljenje je funkcija koncentričnosti jedra, neokrožnosti obloge in sposobnosti poravnave. Zmogljivost optične povratne izgube je funkcija gela za ujemanje indeksa in priprave končne površine vlakna.
1.4 Delovno okolje
Izbrani preskusi v kombinaciji z resnostjo in trajanjem so reprezentativni za zunanje zaprto okolje, ki je v standardu EN IEC 61753 1 opredeljeno kot kategorija OP. Za zagotovitev, da je izdelek mogoče uporabljati v zunanjih ohišjih, škatlah ali uličnih omaricah za kategorije A, G ali S (kot je opredeljeno v standardu EN IEC 61753 1), je razpon najnižje temperature razširjen na –40 °C in dodana je bila zahteva v zvezi s potopitvijo v vodo za začasne poplavne razmere.
1.5 Zanesljivost
Medtem ko znaša pričakovana tehnična življenjska doba izdelka v tem okolju vsaj 20 let, skladnost s to specifikacijo ne zagotavlja zanesljivosti izdelka. Pričakuje se, da naj bi to napovedali v okviru priznanega programa za oceno zanesljivosti.
1.6 Zagotavljanje kakovosti
Skladnost s to specifikacijo ne zagotavlja doslednosti izdelave izdelka. Pričakuje se, da naj bi to vzdrževali v okviru priznanega programa za zagotavljanje kakovosti.

1 Scope
1.1 Product definition
This document contains the initial, start of life dimensional, optical, mechanical and environmental performance
requirements, which single mode mechanical splice needs to meet in order for it to be categorized as a
European standard product.
Although, in this document, the product is qualified for EN IEC 60793-2-50 type B-652.D single mode fibres, it
is also suitable for mechanical splicing of other single mode fibres with 125 µm diameter glass cladding.
Also mechanical splices designed for connections of buffered or secondary coated fibres and cords according
to EN 60794-2-50:2008 are covered by this document.
1.2 Interoperability
The installed mechanical splice fits into optical fibre management system with optical splice cassettes or splice
trays as defined in EN IEC 61756-1. This document specifies the following two physical interface dimensions:
— cross sectional profile with width, height or diameter (in millimetres);
— length (in millimetres).
1.3 Expected performance
In this document, the performance of the mechanical splice is given with identical fibres only as specified in
Annex A. Losses associated with tolerances in fibre cladding diameter and mode field mismatch are not taken
into account. The measured attenuation is a function of the core concentricity, cladding non-circularity and
alignment capability. The optical return loss performance is a function of the index matching gel and the fibre
end face preparation.
1.4 Operating environment
The tests selected combined with the severities and durations are representative of an outdoor enclosed
environment defined as category OP in EN IEC 61753-1. To ensure that the product can be used in outdoor
closures, boxes or street cabinets for categories A, G or S (as defined in EN IEC 61753-1) the specified lower
temperature is extended to −40 °C and a water immersion requirement for temporary flooding conditions has
been added.
1.5 Reliability
Whilst the anticipated service life expectancy of the product in this environment is at least 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.
1.6 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.
