BS EN 50411-3-4:2019

This standard BS EN 50411-3-4:2019 Fibre management systems and protective housings to be used in optical fibre communication systems. Product specifications is classified in these ICS categories:

• 33.180.20 Fibre optic interconnecting devices

1.1 Product definition

This document contains the dimensional, optical, mechanical and environmental performance requirements of a fully installed optical fibre wall or pole mounted box, in order for it to be categorized as a European Standard product.

The typical configuration is splicing of incoming fibres to optional splitters and/or to pigtails, connecting pigtail plugs on one side to patchcord plugs on the other side, using adapters.

A box is a protective housing containing a fibre management system with splice trays of various fibre separation levels and connector mounting plates. The box may contain one or more of the following:

• storage and routing for fibre and cable;

• uncut fibre cable storage;

• splice trays;

• adapters and connectors;

• 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 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 splices. For housings with a higher number of splices and connectors, EN 50411-4-1 (street cabinets) can be used.

Boxes for fibre splices only are covered in EN 50411-3-1.

1.2 Operating environment

The tests selected, combined with the severity and duration, are representative of indoor and outside plants for above ground environments defined by EN IEC 61753-1:

• category C: Controlled (indoor) environment;

• category A: Aerial (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 can 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 can be maintained using a recognized quality assurance programme.

1.5 Allowed fibre and cable types

This box standard accommodates EN IEC 60793-2-50 singlemode 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.
