1 Scope
EN 50288-4-2 is a sectional specification for screened cables, characterised from 1 MHz up to
600 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 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.
This sectional specification contains the electrical, mechanical, transmission and environmental
performance characteristics of the cables, when tested in accordance with the referenced test
methods.
This sectional specification is to be read in conjunction with EN 50288-1 that 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.
