30、l Committee CENELEC TC 215, Electrotechnical aspects of telecommunication equipment. 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
31、national standards conflicting with this document have to be withdrawn (dow) 2021-03-19 This document supersedes EN 50173-2:2007 + A1:2010 + AC:2011.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 sup
32、port 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
33、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
34、 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, se
35、ries 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

37、 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. BS EN 50173-2:2018EN 50173-2:2018 (E) 6 Introduction The importance of cabling infrastructure is similar to that of other fundamental utilities
38、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 c
39、ommercial 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
40、; 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 relationsh
41、ips 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).

44、cluding: CLC/TR 50173-99-1, Cabling guidelines in support of 10 GBASE-T; BS EN 50173-2:2018EN 50173-2:2018 (E) 8 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
45、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
46、 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 ea
47、sy 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 cons
48、truction 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
49、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 de
