1 Scope
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)

4.1 Optical fibre wall box housing
An optical fibre wall box comprises a housing that is attached to wall and the ends of the joined cable sheath.
The wall box has a means of containing and protecting the fibres, splices, and other passive optical devices.

Wall boxes used for blowing cable or fibre comprises an access housing that allows the interconnection of cable
microducts or tubes where the ends of the microducts or cables containing empty tubes are contained. The wall
box also contains an FSM.
- 9 - EN 50411-3-1:2012
The fibre management wall box provides facilities for the environmental protection, housing for fibre
management systems and sealing of input and output optical cables for category G. In order to comply with the
standard, the optical functionality, physical, geometrical and mechanical requirements are defined.

The following table illustrates the concept of a single wall box design/size being able to accommodate various
fibre separation levels in a splice wall box for SC and SE.

The design of the wall box housing shall allow the jointing of two or more cable ends in the following
configurations or applications:

Common wall boxes covering:
(T) Track wall box configuration used on customer feed cable with a minimum of 2 cable entries specified for
each wall box size in the tables, typical when joining two cables along a track.

(S) Spur wall box configuration used on local feeder cable with minimum of 3 cable entries, typically a cable
drop off point to along a track feeder cable.

(D) Distribution wall box configuration used on a local feeder cable with a minimum of 6 cable entries to
distribute smaller cables to different locations.

NOTE Cable entries can be more than one cable per cable entry port.

The design of the wall box housing shall allow the joining together of at least one pair of cables which are not at
the end of a cable section, without cutting all fibres between both cable openings. This application is generally
known as distribution joint or external node, but also called a mid-span or balloon splice wall box.

It is desirable that the wall box can be re-opened when necessary without interruption or disturbance of the
traffic of the live circuits.
4.2 Cable seals/fixings
For category G the cable entry or exit ports in the wall box must have a sealing and fixing system that can be
either:
a) Dedicated heat activated with heat source, for example, electrical, infrared, hot air or flame:
1) thermo-shrinkable materials;
2) hot melt adhesives;
3) polyethylene injection welding;
b) Cold applied:
1) mastic, tapes, pastes, potting compounds, gels and cold adhesives;
2) o-rings, grommets, rubber shapes, pre-expanded tubing are cold processes;
c) Combined heat activated and cold applied:

1) The optical fibre wall box allows for a physical housing structure that provides for optical cable fixing,
sealing, anchoring, water and gas blocking, storage and routing up to the input and output fibres of
the fibre or microduct management system.

4.3 FMS organiser system
The organiser system provides means for routing, storing and protecting of fibre splices or other passive optical
devices in a predetermined order, from one cable sheath opening to another.

Fibre circuits may be separated to an appropriate separation level. This will limit the risk of interruption of traffic
to those fibres that belong to the same group of circuits.
• Single circuit (SC) is a fibre management system that is a group of fibres providing 1 termination or service
of 1 or 2 fibres. In this document a Single Circuit is considered to be a circuit of 2 fibres. If the separation
level for one termination is more than 2 fibres, then the appropriate number of fibres can be stored on one
tray of the single circuit system.

• Single element (SE) is a fibre management system that is a cable subassembly comprising one or more
optical fibres inside a common covering e.g. tube or inside one groove of a grooved cable (slotted core
cable). Single Elements provide more than one termination or circuit of typically 12 fibres. In this document a
Single Element is considered to be a group of 12 fibres.
• Single ribbon (SR) is a fibre management system that is a cable subassembly comprising one optical
ribbon. Single Ribbon is a group of fibres providing one termination or service of typically 4, 8 or 12 fibres.

• Multiple element (ME) is a fibre management system that provides all necessary equipment to connect a
defined number of incoming and outgoing fibres/cables. It comprises storage and protection of fibres and
interconnections in one splice tray for more than one Single Element. Typically splice tray capacities
between 24 and 144 fibres.
• Multiple ribbon (MR) fibre management provides all necessary equipment to connect a defined number of
incoming and outgoing fibre ribbons that are generally housed within a singe tube or slot within the cable.
This tube is fixed to the entry and exit ports of the splice tray. It comprises storage and protection of more
than one single ribbon, but typically six or more fibre ribbons and their interconnections in a si
