Information technology - Generic cabling systems - Part 10: Single pair cabling
This document specifies 1-pair cabling and can be used in conjunction with all the space-specific standards of the EN 50173 series but especially EN 50173-3 and EN 50173-6.
NOTE 1-pair cabling for EN 50173-2, EN 50173-4 and EN 50173-5 is for further study.
It delivers 1-pair cabling specifications to extend generic cabling systems according to the EN 50173 series.
This document specifies the:
- structure and minimum configuration for extension of generic cabling by 1-pair cabling;
- interfaces at the service outlet (SO/TO);
- performance requirements for cabling links and channels;
- implementation requirements and options;
- performance requirements for cabling components;
- conformance requirements and verification procedures.
This document takes into account the requirements specified in application standards listed in Annex C.

Technologies de l'information - Systèmes de câblage générique - Partie 10: Câblage mono-paire
Le présent document spécifie le câblage à 1 paire et peut être utilisé conjointement avec les normes spécifiques aux différents espaces de la série EN 50173, et plus particulièrement l’EN 50173-3 et l’EN 50173-6.
NOTE Le câblage à 1 paire destiné aux espaces couverts par l’EN 50173-2, l’EN 50173-4 et l’EN 50173-5 est soumis à étude ultérieure.
Il donne des spécifications de câblage à 1 paire afin d’étendre le domaine d’application des systèmes de câblage générique conformément à la série EN 50173.
Le présent document spécifie:
- la structure et la configuration minimale pour étendre le domaine d’application du câblage générique à l’aide du câblage à 1 paire;
- les interfaces au niveau de la prise de service (prise de services (SO, Service Outlet)/prise de télécommunication (TO, Telecommunications Outlet));
- les exigences de performances concernant les liaisons et canaux de câblage;
- les exigences et les options de mise en œuvre;
- les exigences de performances concernant les composants du câblage;
- les exigences de conformité et les procédures de vérification.
Le présent document tient compte des exigences spécifiées dans les normes d’application énumérées à l’Annexe C.
