The following dates are fixed: latest date by which this document has to be implemented at national level by publication of an identical national standard or by endorsement (dop) 2019-03-19 latest date by which the nationa
35、l standards conflicting with this document have to be withdrawn (dow) 2021-03-19 This document supersedes the text of EN 50173-4:2007 + A1:2010 + A2:2012.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 applica
36、tions 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 t
37、hese 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
38、 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
39、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 thi
40、s 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
41、) 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;
42、 f) removes CCCB cabling and relevant component requirements; BS EN 50173-4:2018EN 50173-4:2018 (E) 7 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.

43、E) 8 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,
44、 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 conta
45、ins 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
46、 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 ser
47、ies; 2) installation (EN 50174 series); 3) bonding (EN 50310).
