LWL-Spleißkassetten und -Muffen für die Anwendung in LWL Kommunikationssystemen - Produktnorm - Teil 3-6: Mechanische Spleiße für Mehrmoden-Fasern

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 -- Part 3-6: Epissure mécanique de fibres multimodales

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.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated references,

3 Description
3.1 General
A multimode mechanical fibre splice is a passive optical interconnection component which provides optical
and mechanical continuity between two optical fibres. The products described in this specification are based
on mechanical alignment of two cleaved fibres. The fibres are protected against ingress of dust or water by a
sealing material, generally an index matching gel, to both minimise reflections and to improve attenuation at
the glass/gel/glass interface.

42 1 Scope
43 1.1 Product definition
44 This standard contains the initial, start of life dimensional, optical, mechanical and environmental

45 performance requirements, which a multimode mechanical splice must meet in order for it to be categorised
46 as an EN standard product.
47 Since different variants and grades of performance are permitted, product marking and identification details
48 are given in 3.5.
49 Although in this document the product is qualified for EN 60793-2-10:2007, type A1a.1, A1a.2, A1a.3 and A1b
50 multimode fibres it may also be suitable for other fibre types.
51 1.2 Interoperability
52 The installed mechanical splice fits into a fibre management system with optical fibre splice cassettes or
53 splice trays. This standard specifies the following two physical interface dimensions:
54 • cross sectional profile with width, height or diameter (in millimetres);
55 • length (in millimetres).
56 1.3 Expected performance
57 In this document, the performance of a mechanical splice is given with identical fibres only. Losses
58 associated with fibre cladding diameter and mode field mismatch are not taken into account. The measured
59 attenuation is a function of the core concentricity, cladding non-circularity and alignment capability.
60 The optical return loss performance is a function of the index matching gel and the fibre end face preparation.
61 1.4 Operating environment
62 The tests selected combined with the severities and durations are representative of an outdoor enclosed
63 environment defined as category U in EN 61753-1:2007. To ensure that the product can be used in closures,
64 boxes or street cabinet for categories A, G and S (as defined EN 61753-1:2007) the specified lower
65 temperature is extended to -40 °C and requirements for temporary flooding have been added.
66 1.5 Reliability
67 Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with
68 this specification does not guarantee the reliability of the product. This should be predicted using a
69 recognised reliability assessment programme.
70 1.6 Quality assurance
71 Compliance with this specification does not guarantee the manufacturing consistency of the product.
72 This should be maintained using a recognised quality assurance programme.

77 3 Description
78 A multimode mechanical fibre splice is a passive optical interconnection component which provides optical
79 and mechanical continuity between 2 optical fibres or cables. The products described in this specification are
80 based on mechanical alignment of 2 cleaved fibres. The fibres are protected against ingress of dust or water
81 by a sealing material, generally an index matching gel, to both minimise reflections and to improve
82 attenuation at the glass/gel/glass interface.
83 Some splices may have a limited reinstallation capability. In this case the re-installability shall be clearly
84 stated and the re-installation test 9 in 8.3 shall be conducted.
85 3.1 Mechanical splice
86 An optical fibre mechanical splice body contains the following pre-assembled elements:
87 – an alignment device;
88 – a sealing and index matching gel inside;
89 – a fibre alignment activation device like a spring, wedge or plunger;
90 – a fibre clamping or fixing able to withstand axial fibre loads.
91 Mechanical splices designed for use with cables shall contain strain relief fixing.
92 3.2 Materials
93 Materials which are not specified or which are not specifically described are left to the discretion of the
94 manufacturer. However, the following requirements shall be met:
95 – all materials that are likely to come in contact with personnel shall meet appropriate health and safety
96 regulations;
97 – the sealing and index matching materials shall be compatible with the materials of the fibres and the
98 mechanical splice parts;
99 – all components of the splice shall be resistant to solvents and degreasing agents that are typically used
100 to clean and degrease fibres and cables;
101 – metallic parts shall be resistant to the corrosive influences they may encounter during the lifetime of the
102 product;
103 – exterior polymer materials shall be resistant to mould growth.
104 3.3 Dimensions
105 Outline dimensions are specified. All other dimensions are left to the discretion of the manufacturer.
106 3.4 Colour and marking
107 Marking of the product or packaging shall be in the following order of precedence:
108 a) identification of manufacturer;
109 b) manufacturing date code: year/week;
110 c) manufacturers part number;
111 d) variant identification number.
112 There is no preferred colour specified.
