1 Scope
EN 50288-4-1 is a sectional specification for screened cables, characterised from 1 MHz up to
600 MHz, to be used in horizontal and building backbone wiring as defined in EN 50173.
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, 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.
2 Normative references

3.1 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 50288-1 and the following
apply.
3.1.1
screening of cable
a cable is considered screened when the cable core is covered by a continuous conductive
layer forming part of the shielding and grounding system
Note 1 to entry: d.c. continuity has to be given and minimum shielding requirements have to be met.

The cable element shall be a pair or a quad.
4.4 Identification of cabling elements
Unless otherwise specified, the colour coding for identification is given in IEC 60189-2. The colours
shall meet the requirements of EN 50288-1, 4.4
4.5 Screening of cabling elements
Where appropriate, screening of the cabling elements shall be applied in accordance with 4.5 of
EN 50288-1. When a braid is used, the minimum braid coverage (for mechanical purposes) shall be
60 %. When a foil and braid are used the minimum braid coverage (for mechanical purposes) shall be
30 %. Coverage is defined in EN 50290-2-1.
4.6 Cable make-up
The cable elements shall be laid up in concentric layer(s) or units to form the cable core.
4.7 Filling compound
Not applicable.
4.8 Interstitial fillers
Where fillers are used, they shall meet the requirements of EN 50288-1, 4.8
4.9 Screening of the cable core
The screening of the cable core shall be applied in accordance with EN 50288-1, 4.9
When a braid is used the minimum braid coverage (for mechanical purposes) shall be 60 %. When a
foil and braid are used, and/or where a foil is used over each cabling element, the minimum braid
coverage (for mechanical purposes) shall be 30 %. Coverage is defined in EN 50290-2-1.
