BS EN 50700:2014 pdf free.Information technology—Premises distribution access network (PDAN) cabling to support deployment of optical broadband networks.
BS EN 50700 This European Standard specifies the optical fibre optical fibre access network cabling within multi- subscriber premises termed the premises distnbution access network (PDAN). The premises may comprise single or multiple buddings.
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.

The OAP is an optional functional element within the PDAN cabling and is used to enable a service provider to install an external network test interface (ENTI) typically adjacent to the SI. The OAP potentially degrades the transmission performance of the PDAN and should only be installed where there is evidence to suggest that at least one potential service provider may require such an ENTI design (see 5.8.5).BS EN 50700 pdf download.
