Information technology - Premises distribution access network (PDAN) cabling to support deployment of optical broadband networks
This European Standard specifies the optical fibre access network cabling within multi-subscriber premises (which may comprise single or multiple buildings) and intended to support deployment of optical broadband networks. The cabling within the subscriber space for onward distribution of services beyond the customer premises equipment is not specified. Cabling defined by this standard supports a wide range of broadband applications delivering services including voice, data, text, image and video. This European Standard specifies: a) the structure and configuration of the optical fibre cabling; b) cabling performance requirements; c) implementation options. Safety (electrical safety, optical safety and protection, fire, etc.) and electromagnetic compatibility (EMC) requirements are outside the scope of this European Standard and are covered by other standards and regulations. However, information given in this European Standard may be of assistance in meeting these standards and regulations.
Informationstechnik - Standortverkabelung als Teil des optischen Zugangsnetzes von optischen Breitbandnetzen
Diese Europäische Norm legt die Verkabelung von Zugangsnetz en mit Lichtwellenleitern an Standorten mit mehreren Teilnehmern (welche eines oder mehrere Gebäude umfassen dürfen) und ist vorgesehen, die Verwendung optischer Breitbandnetze zu unterstützen. Die Verkabelung im Teilnehmerbereich zur Weiterverteilung der Dienste über die Standorteinrichtungen hinaus wird nicht festgelegt. Die in dieser Norm festgelegte Verkabelung unterstützt einen weiten Bereich von breitbandigen Netz-anwendungen, welche Dienste einschließlich Sprache, Daten, Text, Bild und Film bereitstellen. Diese Europäische Norm legt fest: a) die Struktur und die Konfiguration der Lichtwellenleiterverkabelung; b) Anforderungen an die Leistungsfähigkeit der Verkabelung; c) Wahlmöglichkeiten für die Ausführung. Anforderungen an Sicherheit (elektrische Sicherheit und Schutz vor Zerstörung, optische Leistung, Feuer usw.) und elektromagnetische Verträglichkeit (EMV) gehören nicht zum Anwendungsbereich dieser Europä-ischen Norm und werden von anderen Normen und Vorschriften behandelt. Jedoch kann die in dieser Euro-päischen Norm gegebene Information bei der Einhaltung dieser Normen und Vorschriften hilfreich sein.

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;
• 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 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 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 provider’s infrastructure to an 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 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 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 demarcation 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 location 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).
