Description of 21/30391370 DC 20211.1 Product definition This document contains the dimensional, optical, mechanical and environmental performance requirements of a fully installed optical fibre wall or pole mounted box for up to 288 fibre splices, in order for it to be categorized as a European standard product. The typical configuration is splicing of incoming fibres to optional splitters, connecting on the other side to outgoing fibres. A box is a protective housing containing a fibre management system with splice trays of various fibre separation levels. The box can contain one or more of the following: — storage and routing for fibre and cable; — uncut fibre cable storage; — splice trays; — passive optical devices (optical splitters or WDM). A box can be installed on a vertical indoor or outdoor surface above ground level. If the box is required to be relocatable with cables attached, the following additional tests are expected to be performed: — cable bending; — cable torsion. This document specifies the number of splice trays and splice capacity for each fibre separation level. The maximum capacity is 288 splices. For housings with a higher number of splices, EN 50411 4 1 (street cabinets) can be used. Boxes for fibre splice and patchcord connections are covered in EN 50411 3 4. 1.2 Operating environment The tests selected, combined with the severity and duration, are representative of indoor and outside plant for above ground environments defined by EN IEC 61753 1: — category C: Controlled (indoor) environment; — category A: Aerial (outdoor above ground) environment. 1.3 Reliability Whilst the anticipated service life expectancy of the product in this environment is 20 years, compliance with this document does not guarantee the reliability of the product. This is expected to be predicted using a recognized reliability assessment programme. 1.4 Quality assurance Compliance with this document does not guarantee the manufacturing consistency of the product. This is expected to be maintained using a recognized quality assurance programme. 1.5 Allowed fibre and cable types This box standard accommodates EN 60793 2 50 single-mode fibres and EN 60793 2 10 A1-OM2 to A1-OM5 and A1-OM1 multimode fibres and all EN 60794 series optical fibre cables with various fibre capacities, types and designs.
