This European Standard was approved by CENELEC on 2002-11-01. CENELEC members are bound to
comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European
Standard the status of a national standard without any alteration.
Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.
This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and
notified to the Central Secretariat has the same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Czech Republic,
Denmark, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta,
Netherlands, Norway, Portugal, Slovakia, Spain, Sweden, Switzerland and United Kingdom.

Foreword
This European Standard has been prepared by Technical Committee CENELEC/TC 215 „Electrotechnical
aspects of telecommunication equipment" under the framework of the Mandates M/212 on
„Telecommunication cables and cabling systems" and M/239 on „Air traffic management equipment and
systems".
The text of the draft was submitted to the formal vote and was approved by CENELEC as EN 50173-1 on
2002-11-01.
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) 2003-11-01
- latest date by which the national standards
conflicting with the EN have to be withdrawn (dow) 2003-11-01
The first edition of this European Standard had been developed to enable the application-independent pre-
cabling of office premises. Its basic principles, however, are applicable also in various other situations
including industrial premises and residential buildings, and TC 215 has started to establish relevant European
Standards which address the specific requirements of these environments. In order to point out the
commonalities of these cabling design standards, TC 215 has decided to publish them as individual parts of
the series EN 50173, thus also acknowledging that nowadays standards users recognize the designation
“EN 50173” as a synonym for generic cabling design.
This European Standard, EN 50173-1, supersedes both EN 50173:1995 and EN 50173:1995/A1:2000 and
constitutes a complete revision thereof (it is related to, but not identical with, ISO/IEC 11801:2002). Essential
changes include the following:
- centralized generic cabling in addition to hierarchical three-level topology,
- new modelling of the horizontal cabling subsystem with an optional consolidation point,
- new channel Classes E and F for balanced cabling and associated component Categories 6 and 7,
- classification of optical fibre cabling channels and associated component requirements,
- limits for all channel parameters based on formulae instead of discrete values at key frequencies,
- maximum channel lengths (horizontal and backbone subsystem) depend upon implementation model,
- requirements for cords and jumpers revised,
- requirements on installation aspects and administration replaced by reference to relevant EN,
- new Annexes with link performance/permanent link performance limits and on electromagnetic
characteristics of cabling; Annex with supported applications updated.
Annexes designated “normative” are a part of this standard. Annexes designated “informative” are for
information only. In this standard, Annexes A and D are normative, Annexes B, C, E, F and G are informative.
