DIN EN 50288-9-2:2016-04

This sectional specification covers screened cables, characterised from 1 MHz up to 1 000 MHz, to be used as work area cables to connect a telecommunications outlet to the terminal equipment and for patch cord cables to establish connections on a patch panel as defined in EN 50173. Work area and data centre cables may also be used as patch cord cables in any distributor of a generic building wiring system to interconnect with equipment or to cross-connect between cabling systems. This sectional specification contains the electrical, mechanical, transmission and environmental performance characteristics and requirement of the cables when tested in accordance with the referenced test methods. This sectional specification should be read in conjunction with EN 50288-1, which contains the essential provisions for its application. The cables covered in this sectional specification are intended to operate with voltages and currents normally encountered in communication systems. These cables are not intended to be used in conjunction with low impedance sources, for example, the electric power supplies of public utility mains. For the application of this document, the terms according to EN 50288-1 and the term cable screening apply. A cable is considered to be screened if the cable core is provided with a continuous conductive layer which is part of the screening and grounding system. Informative Annex A provides recommended maximum voltage, current, current density, and conductor temperature values for cables used in POE applications. Informative Annex B contains the form for design specification of screened work area cables, patch cord cables and data centre cables from 1 MHz to 1 000 MHz for use in industrial or rough environmental conditions.
