The following dates were fixed:national standard or by endorsement(dop)2010-05-01latest date by which the national standards conflicting with the EN have to be withdrawn(dow)2012-05-01latest date by which the EN has to be implemented at national level by publication of an identicalEN 50174 comprises three parts. All three parts support the specification, implementation and operation of information technology cabling. There are specific requirements for cabling systems that are in accordance with the design requirements of the EN 50173 series. However, the three parts also apply to cabling systems of any design including those in accordance with standards such as EN 50098-1 or EN 50098-2.This part, EN 50174-1, is concerned with specification, quality assurance, documentation and administration of information technology cabling to be installed, together with its subsequent operation and maintenance. It sets out the responsibilities of information technology cabling installers and premises owners or appointed representatives separately, and is intended to be referenced in relevant contracts.It does not cover those aspects of installation associated with the transmission of signals in free space between transmitters, receivers or their associated antenna systems (e.g. wireless, radio, microwave or satellite).BS EN 50174-1:2009EN 50174-1:2009 47 ContentsIntroduction. 51Scope and conformance. 81.1Scope . 81.2Conformance. 82Normative references. 83Terms, definitions and abbreviations . 93.1Terms and definitions . 93.2Abbreviations . 124Requirements for specifying installations of information technology cabling . 124.1Documentation . 124.2Planning . 184.3Products and processes. 224.4External network service provision . 234.5Operating procedures . 244.6Maintenance. 275Requirements for installers of information technology cabling . 285.1Documentation and administration . 285.2Products and processes. 295.3Power supplies . 305.4Surveys . 306Installation complexity. 316.1Requirements . 316.2Recommendations . 31Annex A (normative) Minimum requirements for technical specifications and quality plans. 32A.1General. 32A.2Technical specification . 32A.3Quality plan . 32Annex B (normative) Polarity maintenance: Connecting hardware for multiple optical fibres . 33B.1General. 33B.2Duplex connecting hardware interfaces. 33B.3Array connecting hardware interfaces . 37Annex C (informative) Terminating balanced cables on terminating blocks in distributors . 42C.1General. 42C.2The use of the same type of connector at each end of a cable . 42C.3The use of a different type of connector at each end of a cable. 42C.4Relation between the pins of connectors according to EN 60603-7 and the tags of aterminating block . 42Annex D (informative) Compatibility between transmission systems (balanced and unbalanced)sharing the same cable sheath within information technology cabling . 43D.1Introduction . 43D.2Recommendations concerning cable sharing . 43D.3Factors to be taken into account to ensure satisfactory performance . 44D.4Guidelines for reducing interference between transmission systems within the same cable sheath. 45D.5Cabling qualification . 45D.6Particular installation requirements and recommendations . 45D.7Cable management . 46D.8Regulatory aspects . 46Bibliography. 47FiguresFigure 1 Schematic relationship between the EN 50174 series and other relevant standards . 6Figure B.1 Duplex connecting hardware plug . 34Figure B.2 Duplex connecting adapter . 34Figure B.3 Duplex patch cord . 34Figure B.4 Views of crossover patch cords . 35Figure B.5 Optical fibre sequences and adapter orientation in patch panel for the Symmetrical PositionMethod . 36Figure B.6 Optical fibre sequences and adapter orientation in patch panel for the Reverse-PairPosition Method. 36Figure B.7 Array connector cable or patch cord (key-up to key-up). 38Figure B.8 Array adapter with aligned keyways . 38Figure B.9 Transition assembly . 39Figure B.10 Connectivity method for duplex cabling . 40Figure B.11 Connectivity method for array cabling . 41TablesTable 1 Contextual relationship between EN 50174 series and other standards relevantfor information technology cabling systems . 7Table 2 Minimum requirements of administration systems . 25Table 3 Minimum requirements of operational administration systems . 26Table 4 Level of installation complexity. 31Table 5 Level of operational complexity . 31Table A.1 Minimum requirements for technical specification .
