European foreword

This document (EN 50173-2:2018) was prepared by the Technical Committee CENELEC TC 215,

Electrotechnical aspects of telecommunication equipment.
The following dates are fixed:
— latest date by which this document has to be (dop) 2019-03-19
implemented at national level by publication of
an identical national standard or by
endorsement
— latest date by which the national standards (dow) 2021-03-19
conflicting with this document have to be
withdrawn
This document supersedes EN 50173-2:2007 + A1:2010 + AC:2011.

The previous editions of 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.

This edition of EN 50173-2:

a) introduces new balanced cabling component Categories 8.1 and 8.2 to support new channel Classes I

and II as well as optical fibre categories OM5 and OS1a;
b) amends various other subclauses, tables and figures;
c) aligns the document structure across all parts of the series.

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

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 and between the buildings of office premises, or office spaces

within other types of building.
Additionally those premises can include:
— industrial spaces for which generic cabling is specified in EN 50173-3;
— data centre spaces for which generic cabling is specified in EN 50173-5.

Generic cabling for distributed building services in office spaces 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;
---------------------- Page: 9 ----------------------
SIST EN 50173-2:2018
EN 50173-2:2018 (E)

— 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 system – 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 including, but not

restricted to, those in EN 50173-1:2018, Annex F in a range of installation and operating environments;

— a flexible scheme such that modifications are both easy and economical;
— a multi-vendor supply chain within an open market for cabling components.
In addition this standard provides:

a) relevant industry professionals with guidance allowing the accommodation of cabling before specific

requirements are known; i.e. in the initial planning either for construction or refurbishment and for further

deployment as the requirements of areas are defined;

b) industry and standardization bodies with a cabling system which supports current products and provides

a basis for future product development and applications standardization.

Applications addressed in this standard include those developed by the Technical Committees of IEC

(including the subcommittees of ISO/IEC JTC 1) and study groups of ITU-T.

Physical layer requirements for the applications listed in EN 50173-1:2018, Annex F, have been analysed to

determine their compatibility with the cabling performance specified in this standard and, together with

statistics concerning premises geography from different countries and the models described in Clause 4,

have been used to develop the requirements for cabling components and to stipulate their arrangement into

cabling systems.
As a result, this standard:

a) specifies a structure for generic cabling supporting a wide variety of applications including, but not

restricted to, those in EN 50173-1:2018, Annex F;

b) adopts balanced cabling channel and link Classes E, EA, F and FA, specified in EN 50173-1;

c) adopts optical fibre cabling channel and link requirements specified in EN 50173-1;

d) adopts component requirements, specified in EN 50173-1, and specifies cabling implementations that

ensures performance of links and of channels meeting the requirements of a specified group (e.g. Class)

of applications.

Life expectancy of generic cabling systems can vary depending on environmental conditions, supported

applications, aging of materials used in cables, and other factors such as access to pathways (campus

pathways are more difficult to access than building pathways).

With appropriate choice of components, generic cabling systems meeting the requirements of this standard

are expected to have a life expectancy of at least ten years.
