Information technology - Generic cabling systems - Part 2: Office premises
This European Standard specifies generic cabling that supports a wide range of communications services for use within office premises, or office areas within other types of premises, that comprise single or multiple buildings on a campus. The requirements of this standard may be applied to other premises that are not explicitly specified within other parts of the EN 50173 series of standards. It covers balanced cabling and optical fibre cabling. This European Standard is based upon and references the requirements of EN 50173-1. This European Standard contains additional requirements that are appropriate to office premises in which the maximum distance over which communications services have to be distributed is 2 000 m. The principles of this European Standard may also be applied to installations that do not fall within this range. In addition to the requirements of EN 50173-1, this European Standard specifies: a) an extended structure and configuration for generic cabling within office premises in support of a wide range of services including voice, data, text, image and video; b) implementation options; Safety (electrical safety and protection, optical power, fire, etc.) and electromagnetic compatibility (EMC) requirements are outside the scope of this European Standard and are covered by other standards and regulations. However, information given in this international Standard may be of assistance in meeting these standards and regulations.

Foreword
This European Standard was prepared by the Technical Committee CENELEC TC 215, Electrotechnical
aspects of telecommunication equipment.
The text of the draft was submitted to the formal vote and was approved by CENELEC as EN 50173-2 on
2007-04-11.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2008-05-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2010-05-01
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.
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 premises
EN 50173-3 Information technology – Generic cabling systems – Part 3: Industrial premises
EN 50173-4 Information technology – Generic cabling systems – Part 4: Homes
EN 50173-5 Information technology – Generic cabling systems – Part 5: Data centres
This European Standard, EN 50173-2, together with EN 50173-1:2007 supersedes, EN 50173-1:2002. It is
an editorial revision of EN 50173-1:2002 and contains those specifications of EN 50173-1:2002, which are
relevant to generic cabling systems to be operated in office premises, referencing the general requirements of
EN 50173-1:2007.

Introduction
The importance of the information technology cabling infrastructure is similar to that of other utilities such as
heating, lighting and electricity supplies. As with other utilities, interruptions to service can have serious
impact. Poor quality of service due to lack of planning, use of inappropriate components, incorrect installation,
poor administration or inadequate support can threaten an organisation's effectiveness.
Historically, the cabling within premises comprised both application-specific and multipurpose networks.
Standards within the EN 50173 series have enabled a controlled migration to generic cabling (with an
associated reduction in the use of application-specific cabling) and supported the development of high data
rate applications based upon defined cabling models.
This European Standard, EN 50173-2, has been prepared to reflect the demands of generic cabling within
office premises and provides:
a) users with an application independent generic cabling system and an open market for cabling
components;
b) users with a flexible cabling scheme such that modifications are both easy and economical;
c) building professionals (for example, architects) with guidance allowing the accommodation of cabling
before specific requirements are known; i.e., in the initial planning either for construction or refurbishment;
d) industry and standardisation bodies with a cabling system which supports current products and provides a
basis for future product development and applications standardisation.
This European Standard specifies multi-vendor cabling, and is related to:
- the associated standard covering general requirements for generic cabling within premises (EN 50173-
