scope:

This European Standard covers wall boxes for up to 144 fibre connectors. Wall boxes for fibre splices are covered in EN 50411-3-1:2012. 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. If the wall box is required to be relocated, with cables attached, this would be conditional on meeting the following additional tests: - Cable bending; - Cable torsion. The wall box is a housing containing a fibre management system, containing splice trays of various fibre separation levels, and connector mounting plates. The wall box may contain one or more of the following: - storage and/or routing of cable; - through-box/uncut fibre, cable storage; - connectors; - passive devices. This document specifies the number of splice trays for each fibre separation level.
