What is BS EN 50700 - Premises distribution access network (PDAN) cabling to support deployment of optical broadband networks about?
BS 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.
BS EN 50700 specifies:
- The structure and configuration of the optical fibre cabling
- Cabling performance requirements
- Implementation options
Note1: BS EN 50700 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.
Note 2: 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 BS EN 50700.
Note 3: Safety (electrical safety, fire, etc.) and electromagnetic compatibility (EMC) requirements are outside the scope of BS EN 50700 and are covered by other standards and regulations.
Who is BS EN 50700 - Premises distribution access network (PDAN) cabling to support deployment of optical broadband networks for?
BS EN 50700 on premises distribution access network (PDAN) cabling to support deployment of optical broadband networks is useful for:
- Information technology industry
- Service providers and operators of broadband optical networks
- Optical fibre/Cabling installation teams
- Building professionals/ architects
Why should you use BS EN 50700 - Premises distribution access network (PDAN) cabling to support deployment of optical broadband networks?
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 BS EN 50700 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). This enables 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.
BS EN 50700 allows access providers to be aware of the minimum implementation delivered to them when they reach such multi-subscriber premises.
BS EN 50700 maximises the opportunity for network evolution by either the access provider or the service providers using that access infrastructure.
BS EN 50700 provides:
- Access providers with an application-independent optical fibre cabling subsystem
- An open market for cabling components
- 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
