EN 50411-3-6:2013

Fibre organisers and closures to be used in optical fibre communication systems - Product specifications - Part 3-6: Multimode mechanical fibre splice for use in an outdoor protected environment (Cat U)

1.1 Product definition This European Standard contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements which a multimode mechanical splice will meet in order for it to be categorised as an EN standard product. Since different variants and grades of performance are permitted, product marking and identification details are given in 3.5. Although in this document the product is qualified for EN 60793-2-10 type A1a.1, A1a.2, A1a.3 and A1b multimode fibres, it may also be suitable for other fibre types. 1.2 Interoperability The installed mechanical splice fits into a fibre management system with optical fibre splice cassettes or splice trays. This European Standard 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 a mechanical splice is given with identical fibres only. Losses associated with 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 U in EN 61753-1. To ensure that the product can be used in closures, boxes or street cabinet for categories A, G and S (as defined EN 61753-1) the specified lower temperature is extended to -40 °C and requirements for temporary flooding have been added. 1.5 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. 1.6 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.

LWL-Spleißkassetten und -Muffen für die Anwendung in LWL Kommunikationssystemen - Produktnorm - Teil 3-6: Mechanische Spleiße von Mehrmoden-Faser für geschützte Freiluftanwendungen (Kategorie U)

Produktdefinition Diese Europäische Norm enthält die Anfangs- und Maßanforderungen zu Beginn der Lebensdauer sowie die optischen, mechanischen und umweltbezogenen Leistungsanforderungen, die ein mechanischer Spleiß einer Mehrmoden-Faser erfüllen wird, um als EN-Normprodukt eingestuft zu werden. Da verschiedene Varianten und Leistungsklassen zulässig sind, werden in 3.5 Einzelheiten zur Produktkenn¬zeichnung angegeben. Obwohl die nach diesem Dokument qualifizierten Produkte für Mehrmoden-Fasern des Typs A1a.1, A1a.2, A1a.3 and A1b gemäß EN 60793-2-10:2007 sind, können sie auch für andere Fasertypen geeignet sein. 1.2 Passfähigkeit Die installierten mechanischen Spleiße passen in ein Fasermanagementsystem mit LWL-Spleißkassetten oder LWL-Spleißwannen. In der vorliegenden Europäischen Norm werden die beiden folgenden physikalischen Schnitt¬stellenmaße festgelegt: – Querschnitt mit Breite, Höhe oder Durchmesser (in mm); – Länge (in mm). 1.3 Erwartetes Betriebsverhalten Das Betriebsverhalten eines mechanischen Spleißes ist nach dem vorliegenden Dokument nur bei identi-schen Fasern sichergestellt. Verluste im Zusammenhang mit einer Fehlanpassung von Fasermantel-durchmesser und Modenfelddurchmesser bleiben unberücksichtigt. Die gemessene Dämpfung ist eine Funk¬tion der Konzentrizität des Kerns, der Unrundheit des Mantels und der Ausrichtungsfähigkeit. Die optische Rückflussdämpfung ist eine Funktion des Gels mit angepasster Brechzahl und der Vorbereitung der Faser¬endflächen. 1.4 Betriebsumgebung Die ausgewählten Prüfungen in Kombination mit den Prüfschärfe und dauern sind repräsentativ für eine geschlossene Umgebung im Freien nach den Festlegungen für Kategorie U in IEC 61753 1:2007. Damit gewähr¬leistet ist, dass das Produkt in Muffen, Kästen oder Straßenschränken für die Kategorien A, G und S (nach den Festlegungen in EN 61753 1:2007) angewendet werden kann, wurde die festgelegte untere Temperatur auf –40 °C erweitert und es wurden Anforderungen für eine zeitweilige Überflutung aufgenommen. 1.5 Zuverlässigkeit Die erwartete Betriebslebensdauer des Produktes in dieser Umgebung beträgt 20 Jahre, wobei die Einhal-tung dieser Spezifikation die Zuverlässigkeit des Produktes nicht garantiert. Diese sollte mit einem aner-kannten Zuverlässigkeitsbewertungsprogramm vorhergesagt werden. 1.6 Qualitätssicherung Die Einhaltung dieser Spezifikation garantiert nicht die Beständigkeit der Herstellung des Produktes. Diese sollte mit einem anerkannten Qualitätssicherungsprogramm aufrechterhalten werden.

Organiseurs et boîtiers de fibres destinés à être utilisés dans les systèmes de communication par fibres optiques - Spécifications de produits - Partie 3-6: Epissure mécanique de fibres multimodales installée en environnement extérieur protégé (Cat U)

1.1 Définition du produit La présente norme européenne contient les exigences de performances initiales, dimensionnelles, optiques, mécaniques et environnementales, de début de vie, auxquelles une épissure mécanique multimodale satisfera, afin d'être classée comme produit conforme à une norme EN. Dans la mesure où différentes variantes et différentes classes de performances sont autorisées, les détails de marquage et d’identification des produits sont donnés en 3.5. Bien que, dans le présent document, le produit soit qualifié pour des fibres multimodales de types A1a.1, A1a.2, A1a.3 et A1b de l’EN 60793-2-10, il peut également convenir à d’autres types de fibres. 1.2 Interopérabilité Les épissures mécaniques installées s’adaptent à un système de gestion de fibres avec des cassettes ou des plateaux d'épissures de fibres optiques. La présente norme européenne 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 avec des fibres identiques uniquement. Les pertes associées au diamètre de la gaine de fibre et au 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 U dans l'EN 61753-1. Afin de garantir que le produit peut être utilisé dans des enveloppes, des boîtes ou des armoires pour les catégories A, G et S (telles que définies dans l'EN 61753-1), la température inférieure spécifiée est étendue à -40 °C, et des exigences relatives à une immersion temporaire ont été ajoutées. 1.5 Fiabilité Tandis que l'espérance de vie du produit en service prévue dans cet environnement est de 20 ans, la conformité à la présente 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. 1.6 Assurance de la qualité La conformité à la présente spécification ne garantit pas la cohérence de fabrication du produit. Il convient qu’elle soit suivie en utilisant un programme reconnu d'assurance de la qualité.

1 Scope
1.1 Product definition
This European Standard contains the initial, start of life dimensional, optical, mechanical and environmental

performance requirements which a multimode mechanical splice will meet in order for it to be categorised as
an EN standard product.
Since different variants and grades of performance are permitted, product marking and identification details
are given in 3.5.
Although in this document the product is qualified for EN 60793-2-10 type A1a.1, A1a.2, A1a.3 and A1b
multimode fibres, it may also be suitable for other fibre types.
1.2 Interoperability
The installed mechanical splice fits into a fibre management system with optical fibre splice cassettes or
splice trays. This European Standard 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 a mechanical splice is given with identical fibres only. Losses
associated with 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 U in EN 61753-1. To ensure that the product can be used in closures,
boxes or street cabinet for categories A, G and S (as defined EN 61753-1) the specified lower temperature is
extended to -40 °C and requirements for temporary flooding have been added.
1.5 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.
1.6 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.
