Multi-element metallic cables used in analogue and digital communication and control - Part 4-2: Sectional specification for screened cables characterised up to 600 MHz - Work area and patch cord cables

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.

Večelementni kovinski kabli za analogne in digitalne komunikacije in krmiljenje - 4-2. del: Področna specifikacija za zaslonjene kable z lastnostmi do 600 MHz - Kabli za delovna območja in povezovalne vrvice

Standard EN 50288-4-2 je področna specifikacija za zaslonjene kable, ki se lahko uporabljajo za pasovne širine od 1 MHz do 600 MHz kot kabli na delovnem območju za povezavo telekomunikacijske vtičnice s terminalsko opremo, ter za povezovalne vrvice za vzpostavljanje povezav na povezovalni plošči, kot je določeno v standardu EN 50173. Kabli delovnega območja in podatkovnih centrov se lahko uporabljajo tudi kot povezovalne vrvice v katerem koli razdelilniku generičnega stavbnega sistema ožičenja za povezavo z opremo ali navzkrižno povezavo med kabelskimi sistemi. Ta področna specifikacija vsebuje električne, mehanske, prenosne in okoljske karakteristike delovanja kablov pri preskušanju v skladu z navedenimi preskusnimi metodami. Ta področna specifikacija se uporablja skupaj s standardom EN 50288-1, ki vsebuje bistvene določbe za njeno uporabo. Kabli, zajeti v tej področni specifikaciji, so namenjeni za delovanje pri napetostih in tokovih, ki so običajni v komunikacijskih sistemih. Ti kabli niso namenjeni za uporabo z viri z nizko impedanco, na primer z električnim napajanjem javnih omrežij.

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.
