This European Standard contains the dimensional, optical, mechanical and environmental performance  requirements of a fully installed optical fibre wall box, in order for it to be categorized as an EN standard  product.  The typical configuration is splicing of incoming fibres to optional splitters and/or to pigtails, connecting  pigtails plugs on one side to patchcord plugs on the other side, using adapters.  A wall box is a protective housing containing a fibre management system with splice trays of various  fibre separation levels and connector mounting plates. The wall box may contain one or more of the  following:  - storage and routing of fibre and cable;  - uncut fibre cable storage;  - splice trays;  - adaptors and connectors;  - passive optical devices (optical splitters or WDM).  A wall box can be installed on a vertical indoor or outdoor surface above ground level. If the wall box is  required to be relocatable with cables attached, the following additional tests shall be performed:  - cable bending;  - cable torsion.  This document specifies the number of splice trays and splice/connector capacity for each fibre  separation level. The maximum capacity is 144 connectors and splice. For housings with a higher  number of splices and connectors the document prEN 50411-4-1 (Cabinets) should be used.  Wall boxes for fibre splices only are covered in EN 50411-3-1:2012.
