23、S EN 50411-3-6:2013 5 EN 50411-3-6:2013 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 splicewill meet in order for it to be categorised as an EN standa
24、rd 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 t
25、ypes. 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
26、); 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 con
27、centricity, 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 encl
28、osed 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 Reliab
29、ility 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 wi
30、th 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

43、ptical 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/
44、gel/glass interface. BS EN 50411-3-6:2013 7 EN 50411-3-6:2013 Some splices may have a limited reinstallation capability. In this case the re-installability shall be clearly stated and the re-installation test 9 in 8.3 shall be conducted. 3.2 Mechanical splice An optical fibre mechanical splice body
45、contains the following pre-assembled elements: null an alignment device; null a sealing and index matching gel inside; null a fibre alignment activation device like a spring, wedge or plunger; null a fibre clamping or fixing able to withstand axial fibre loads. Mechanical splices designed for use wi
46、th cables shall contain strain relief fixing. 3.3 Materials Materials which are not specified or which are not specifically described are left to the discretion of the manufacturer. However, the following requirements shall be met. null All materials that are likely to come in contact with personnel
47、 shall meet appropriate health and safety regulations. null The sealing and index matching materials shall be compatible with the materials of the fibres and the mechanical splice parts. null All components of the splice shall be resistant to solvents and degreasing agents that are typically used to
48、 clean and degrease fibres and cables. null Metallic parts shall be resistant to the corrosive influences they may encounter during the lifetime of the product. null Exterior polymer materials shall be resistant to mould growth. 3.4 Dimensions Outline dimensions are specified. All other dimensions a
49、re left to the discretion of the manufacturer. 3.5 Colour and marking Marking of the product or packaging shall be in the following order of precedence: a) identification of manufacturer; b) manufacturing date code: year/week; c) manufacturers part number; d) variant identification number. There is no preferred colour specified. BS EN 50411-3-6:2013EN 50411-3-6:2013 8 4 Variants Table
