1.1 Product definition This European Standard covers wall boxes for up to 288 fibre splices. Wall boxes for connectors will be covered in a future part of the EN 50411-3 series. This European Standard covers two environmental service requirements, for use inside a building under category C and externally of buildings under category G both to EN 61753-1:2007. This European Standard contains the initial, start of life dimensional, optical, mechanical and environmental performance requirements of a fully installed optical fibre wall box, in order for it to be categorised as an EN standard product. The wall box must be suitable for fixing to a vertical internal or external surface above ground level. The wall box is a housing containing a fibre management system, containing splice trays of various fibre separation levels, and may contain one or more of the following: • storage and/or routing of cable; • through-box/uncut fibre, cable storage; • passive devices. This document specifies the number of splice trays for each fibre separation level. 1.2 Operating environment The tests selected combined with the severity and duration is representative of indoor and outside plant for above ground environments defined by: EN 61753-1: - category C: Controlled environment - category G: Ground level environment 1.3 Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this European Standard does not guarantee the reliability of the product. This should be predicted using a recognised reliability assessment programme. 1.4 Quality assurance Compliance with this European Standard does not guarantee the manufacturing consistency of the product. This should be maintained using a recognised quality assurance programme. 1.5 Allowed fibre and cable types All types of fibre are permitted for a FMS with a minimum bend radius of 30 mm. A minimum bend of 20 mm can only be used with a B 6 fibre. The box, once tested according to this product specification, will be also suited for other fibre types, for example bend insensitive, dispersion shifted, non-zero dispersion shifted and multimode fibres. This wall box standard allows both single-mode and multi-mode fibre to be used and covers all IEC standard optical fibre cables with their various fibre capacities, types and designs as long as fitting in the box does not contravene the minimum bend radius. The minimum bend radius of fibre depends on its type, and is applicable for all operational wavelengths: • EN 60793-2-10, Type A1 multimode fibre is 30 mm; • EN 60793-2-50, Type B 1.1 and B 1.3 singlemode fibre is 30 mm; (20 mm is accepted for total lengths less than 2 m) • EN 60793-2-50, Type B6-a1, B6-a2 singlemode fibre (ITU-T G.657) is 20 mm (15 mm is accepted for total lengths less than 0,5 m)
