Information technology - Premises distribution access network (PDAN) cabling to support deployment of optical broadband networks

EN 50700 specifies the optical fibre optical fibre access network cabling within multi-subscriber premises termed the premises distribution access network (PDAN). The premises may comprise single or multiple buildings. The cabling specified is intended to be pre-installed, in readiness for subsequent connection of the multi-subscriber premises to an access providers infrastructure to support deployment of optical broadband networks. 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 customer premises equipment. This European Standard specifies: a) the structure and configuration of the optical fibre cabling; b) cabling performance requirements; c) implementation options. 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. Safety (electrical safety, 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.

Foreword
This document (EN 50700:2014) has been prepared by CLC/TC 215 "Electrotechnical aspects of
telecommunication equipment".
The following dates are fixed:
• latest date by which this document has to be
(dop) 2014-11-25
implemented at national level by publication of
an identical national standard or by
endorsement
• latest date by which the national standards
(dow) 2016-11-25

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).

Where the subscribers’ premises are homes, the design of generic cabling beyond 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 Standard provides:
a) access providers with an application independent optical fibre cabling subsystem;
b) an open market for cabling components;

---------------------- Page: 8 ----------------------

SIST EN 50700:2014
- 7 - EN 50700:2014

c) building professionals (for example, architects) with guidance for the accommodation of cabling and
interfaces before 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 assurance 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 relationships 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).
