Information technology - Cabling installation - Part 99-1: Remote powering

Information technology - Cabling installation - Part 99-1: Remote powering

This Technical Report defines requirements and recommendations concerning limits for the application and operation of remote powering using cabling comprising balanced cabling components of Category 5 (minimum) as defined in EN 50173-1. This Technical Report also describes: - a set of specific implementations which are the basis of a mathematical model for the temperature increases in bundles of cables under remote powering conditions; - a matching testing protocol used to provide data for the mathematical model; NOTE The testing protocol was established in order to enable comparison of data from different sources in order to support the development of the mathematical model and to develop appropriate planning and installation rules as suggested by different installation conditions. It is not the role of CLC/TC 215 to develop test methods for balanced, or other, cables and the protocol defined in Annex B is not as such a test method. - the mathematical model that is employed as the basis for the resulting requirements and recommendations. Safety (electrical safety and protection, optical power, fire, etc.) and electromagnetic compatibility (EMC) requirements are outside the scope of this Technical Report and are covered by standards and regulations. However, information given in this Technical Report may be of assistance in meeting these standards and regulations.

Information technology - Premises distribution access network (PDAN) cabling to support deployment of optical broadband networks
SIST EN 50700:2023

This document specifies the optical fibre access network cabling within single- and multi-subscriber premises termed the premises distribution access network (PDAN). The premises can 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 document 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 document specifies: a) the structure and configuration of the optical fibre cabling; b) cabling performance requirements; c) implementation options. Annex A contains information on network segments not covered by this document. 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 document. Safety (electrical safety, fire, etc.) and electromagnetic compatibility (EMC) requirements are outside the scope of this document and are covered by other standards and regulations. However, information given in this document can be of assistance in meeting these standards and regulations.
