European foreword
This document (EN 50173-4:2018) has been prepared by the Technical Committee CENELEC TC 215
"Electrotechnical aspects of telecommunication equipment" in cooperation with the Technical Committee
CENELEC TC 209 "Cable networks for television signals, sound signals and interactive services".
The following dates are fixed:
• latest date by which this document has (dop) 2019-03-19
to be implemented at national level by
publication of an identical national
standard or by endorsement
• latest date by which the national (dow) 2021-03-19
standards conflicting with this document
have to be withdrawn
This document supersedes the text of EN 50173-4:2007 + A1:2010 + A2:2012.
The European Standards EN 50173:1995 and EN 50173-1:2002 have been developed to enable the
application-independent cabling to support ICT applications in office premises. Their basic principles,
however, are applicable to other types of applications and in other types of premises.
TC 215 has decided to establish relevant European Standards which address the specific requirements of
these premises. In order to point out the commonalities of these cabling design standards, these EN are
published as individual parts of the series EN 50173, thus also acknowledging that standards users recognize
the designation “EN 50173” as a synonym for generic cabling design.
At the time of publication of this European Standard, series EN 50173 comprises the following standards:
EN 50173-1 Information technology — Generic cabling systems — Part 1: General requirements
EN 50173-2 Information technology — Generic cabling systems — Part 2: Office spaces
EN 50173-3 Information technology — Generic cabling systems — Part 3: Industrial spaces
EN 50173-4 Information technology — Generic cabling systems — Part 4: Homes
EN 50173-5 Information technology — Generic cabling systems — Part 5: Data centre spaces
EN 50173-6 Information technology — Generic cabling systems — Part 6: Distributed building
services
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. CENELEC shall not be held responsible for identifying any or all such patent rights.
This edition of EN 50173-4:
a) introduces new components 8.1 and 8.2 for balanced cabling to support new channel Classes I and II as
well as optical fibre cabling (OM5) as defined in EN 50173-1:2018;
b) revises the functional elements in Clause 4;
c) clarifies the relation of generic home cabling systems to the network access cabling subsystem in
Clause 4;
d) introduces relevant design objectives for home cabling systems;
e) introduces cable sharing requirements;
f) removes CCCB cabling and relevant component requirements;
g) removes Annex B of the previous edition;
h) aligns the document structure across the EN 50173 series and updates the document both technically
and editorially.
Introduction
The importance of cabling infrastructure is similar to that of other fundamental utilities such as water and
energy supply and interruptions to the services provided over that infrastructure can have a serious impact. A
lack of design foresight, the use of inappropriate components, incorrect installation, poor administration or
inadequate support can threaten quality of service and have commercial consequences for all types of users.
This standard specifies generic cabling within a single home.
The home can contain one or more buildings or can be within a building which contains more than one home
(e.g. one home in a multi-dwelling building).
The campus or backbone cabling connecting individual homes within multi-tenant premises is specified
according to the relevant standard (for instance EN 50173-1 or EN 60728 series).
Generic cabling for distributed building services in homes is specified in EN 50173-6 which addresses all of
the above premises and spaces within them.
Figure 1 and Table 1 show the schematic and contextual relationships between the standards produced by
TC 215 for information technology cabling, namely:
1) this and other parts of the EN 50173 series;
2) installation (EN 50174 series);
3) bonding (EN 50310).

In addition, a number of Technical Reports have been developed to support or extend the application of these
standards, including:
— CLC/TR 50173-99-1, Cabling guidelines in support of 10 GBASE-T;
— CLC/TR 50173-99-2, Information technology — Implementation of BCT applications using cabling in
accordance with EN 50173-4;
— CLC/TR 50173-99-3, Information technology — Generic cabling systems — Part 99-3: Home cabling
infrastructures up to 50 m in length to support simultaneous and non simultaneous provision of
applications.
In addition, a number of cabling design standards have been developed using components of EN 50173-1
(e.g. EN 50098 series and EN 50700).
The generic cabling specified by this standard provides users with:
— an application independent system capable of supporting a wide range of applications in a range of
installation and operating environments;
— a flexible scheme such that modificat
