EN 50288-5-2 is a sectional specification for screened cables, characterised from 1 MHz up to 250 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.<\/p>\n
Work area and data centres 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.<\/p>\n
This sectional specification contains the electrical, mechanical, transmission and environmental performance characteristics of the cables, when tested in accordance with the referenced test methods.<\/p>\n
This sectional specification is to be read in conjunction with EN 50288-1, which contains the essential provisions for its application.<\/p>\n
The cables covered in this sectional specification are intended to operate with voltages and currents normally encountered in communication systems. These cables are not i ntended to be used in conjunction with low impedance sources, for example, the electric power supplies of public utility mains.<\/p>\n
