21、ulti-subscriber premises to enable the delivery of broadband telecommunication services. BS EN 50700:2014- 5 - EN 50700:2014 Introduction Fibre to the home (FTTH) is the subject of standardisation in the form of: Technical Reports such as CLC/TR 50510 which cover general concepts and system planning
22、; component standards that support its implementation; installation standards such as the EN 50174 series. FTTH is a general term applied to the provision of broadband optical networks to residential premises. Some premises accommodate multiple subscribers and these may be residential or commercial
23、enterprises such as offices, data centres, industrial, retail or a mix of these subscriber types. These multi-subscriber premises may consist of one or more buildings. The cabling specified in this standard: constitutes the part of the broadband access network within multi-subscriber premises termed
24、 the premises distribution access network (PDAN); the access network serving single subscriber premises is not normatively addressed in this standard; is intended to be pre-installed, in readiness for subsequent connection of the multi-subscriber premises, to an access providers infrastructure to an
25、 access demarcation point (ADP) - enabling broadband content to be delivered by the service provider(s). Within premises, the importance of the information technology cabling infrastructure is similar to that of other fundamental building utilities such as heating, lighting and mains power. As with
26、other utilities, interruptions to service can have a serious impact. Poor quality of service due to lack of design foresight, use of inappropriate components, incorrect installation, poor administration or inadequate support can disrupt service delivery. This standard: allows access providers to be
27、aware of the minimum implementation delivered to them when they reach such multi-subscriber premises; maximises the opportunity for network evolution by either the access provider or the service providers using that access infrastructure. This standard specifies the cabling between the access demarc
28、ation point (ADP) and the subscriber interface (SI).The transmission performance of the premises cabling between the last operator connection point (LOC) and the ADP is not addressed although the requirements for its accommodation are provided by external reference to the EN 50174 series. The locati
29、on of the LOC may be either outside the premises boundary (see the schematic in Figure 1) or inside the premises, internal or external to a building (see the schematic in Figure 2).

32、 the SI is specified in EN 50173-4. CLC/TR 50173-99-2 and CLC/TR 50173-99-3 provide additional information in relation to cabling design within homes. For other types of subscribers, the design of generic cabling beyond the SI is specified in other standards in the EN 50173 series. This European Sta
33、ndard provides: a) access providers with an application independent optical fibre cabling subsystem; b) an open market for cabling components; BS EN 50700:2014- 7 - EN 50700:2014 c) building professionals (for example, architects) with guidance for the accommodation of cabling and interfaces before
34、specific requirements are known; i.e. in the initial planning either for construction or refurbishment. This European Standard specifies multi-vendor cabling, and is related to: - standards for cabling components developed by Technical Committees of CENELEC and/or IEC; - standards for the quality as
35、surance and installation of information technology cabling (EN 50174 series) and testing of installed cabling (EN 50346 and, by external reference, EN 61280-4-2 and ISO/IEC 14763-3); - applications developed by ETSI and Study Groups of ITU-T. Figure 3 and Table 1 show the schematic and contextual re
36、lationships between the standards produced by TC 215 for information technology cabling, namely: 1) the EN 50173 series where this standard interfaces to the subscriber; 2) installation (EN 50174 series); 3) testing of installed cabling (EN 50346).

This European Standard does not specify either the access network cabling external to the premises or the cabling within the subscriber space for onward distribution of services beyond the cust

Safety practices in relation to optical power hazard are specified in EN 60825-2. Optical powers higher than the hazard levels specified in EN 60825-2 are not considered in this standard.
