30、 for it to be categorised as an EN standard product. Although in this document the product is qualified for EN 60793-2-50 type B1.1 and B1.3 singlemode fibres it may also be suitable for fusion splice protection of multimode fibre with 125 m diameter glass cladding and other singlemode fibres with 1
31、25 m diameter glass cladding at other wavelengths. 1.2 Interoperability The installed fusion splice protector needs to fit into optical fibre splice cassettes or splice trays. This European Standard specifies the following physical interface dimensions: cross sectional profile with width, height or
32、diameter(in millimetres); length (in millimetres). 1.3 Expected performance In this European Standard, the performance of the fusion splice protector is given with selected fibres as specified in Annex A. 1.4 Operating environment The tests selected combined with the severities and durations are rep
33、resentative 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 C, A, G and S (as defined EN 61753-1) the specified lower temperature is extended to -40 C and requirements for temporary flo
34、oding have 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 specification does not guarantee the reliability of the product. This should be predicted using a recognised reliability assessment prog
35、ramme. 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 referenced documents are indispensable for the application o

46、rds (IEC 61753-1:2007) 3 Description 3.1 Fusion splice protector 3.1.1 General A singlemode fibre fusion splice protector is a passive component, which provides mechanical and environmental protection to a single fibre or ribbon fibre fusion splice. The fused fibres are protected against ingress of
47、dust or temporary flooding by a sealing material, generally a polymer material like hot melt adhesive or mastic. BS EN 50411-3-3:2011EN 50411-3-3:2011 - 8 - The products described in this standard are based on various protection types: heat shrinkable splice protector; fold over splice protector (al
48、so called clam shell splice protector). 3.1.2 Heat shrinkable splice protector type Prior to the splicing, the splice protector is put over one of the fibre or ribbon ends. After the fusion of the fibres, the splice protector is placed over the spliced area. After visual centring over the fused area the splice protector is shrunk by heating equipment. The typical fusion splice protector is composed of three elements: 123Key 1 a reinforcement member to give rigidity after the protector is installed in the he
