Fibre management systems and protective housings to be used in optical fibre communication systems. Product specifications. Part 3-3: Singlemode optical fibre fusion splice protectors

Alkalmazási terület

1.1 Product definition This document contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements, which a single mode fusion splice protector need to meet in order for it to be categorized as an EN 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 fusion splice protection of multimode fibre with 125 mikrométer diameter glass cladding and other single mode fibres with 125 mikrométer diameter glass cladding. 1.2 Interoperability The installed fusion splice protector needs to fit into optical fibre splice cassettes or splice trays. This document specifies the following 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 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 representative of an outdoor enclosed environment defined as category OP in EN IEC 61753-1. The “assembly and disassembly” and the “dust” tests are not included since they are not relevant once the product is installed. 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 specification does not guarantee the reliability of the product. This should be predicted using a recognized 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 recognized quality assurance programme.
