This document specifies the measurement at frequencies of E2E links of two- and four-pair balanced cabling of 100 MHz of Class D and 250 MHz of Class E including free connectors which terminate two and four pairs in both field and laboratory conditions. The specifications for E2E links are described in ISO/IEC TR 11801-9902. This document specifies laboratory and field measurement procedures. The requirements for accuracy to measure cabling parameters identified in ISO/IEC TR 11801-9902 are provided in EN 61935-1 and EN 61935-2.

Informationstechnik - Messung von Ende-zu-Ende-Verbindungsstrecken

Die symmetrische Verkabelung dient der Verbindung von Geräten mittels freier Steckverbinder. Es ist bekannt, dass Feldanschlüsse an allen Teilen der Übertragungsstrecke Auswirkungen auf das Leistungsvermögen der Übertragungsstrecke haben. Unzulängliche Anschlüsse können das Leistungsvermögen der Übertragungsstrecke und die Zuverlässigkeit der Datenübertragung beeinträchtigen. Bisher wurde zur Überprüfung von Verkabelung mit Feldanschlüssen das Leistungsvermögen von Übertragungsstrecken der Klasse D oder E nach EN 50173-1 gemessen. Bei der Messung von Übertragungsstrecken der Klasse D oder E werden die Verbindungen am Ende des Kabels nicht berücksichtigt. Bei der Messung von Übertragungsstrecken der Klasse D oder E werde die Auswirkungen unzulänglicher Anschlüsse der Verbindungen am Ende auf das Leistungsvermögen nicht ermittelt. Bei der Messung des Leistungsvermögens einer Ende-zu-Ended-(EzE)-Verbindungsstrecke werden die Anschlüsse an beiden Enden der symmetrischen Verkabelung berücksichtigt. Dieses Dokument beschreibt die Messung von EzE-Verbindungsstrecken symmetrischer Verkabelungen mit zwei und vier Paaren von Klasse D mit 100 MHz und Klasse E mit 250 MHz mittels Messverfahren mit Labor-und Feldprüfgeräten. Das Leistungvermögen von EzE-Verbindungsstrecken ist in ISO/IEC TR 11801-9902 beschrieben. Diese Europäische Norm ist eines der Dokumente zur Unterstützung der Europäischen Normen und Technischen Berichte über informations- und telekommunikationstechnische Verkabelung, die von CLC/TC 215 erstellt werden.

Introduction

Balanced cabling is constructed for connecting equipment using free connectors. It is known that field

termination in all parts of the channel has an influence on the channel performance.

Poor termination can cause problems in the channel performance and can affect reliable data transmission.

Until now, a verification of the field terminated cabling was done by measurement of the channel

performance of Channel Class D or E according to EN 50173-1. The measurement of Channel Class D or E

excludes the connections at the end of the cable. The measurement of Channel Class D or E does not

identify the influence to the performance caused by bad terminations of the connections at the end.

The measurement of performance of end-to-end (E2E) link includes the termination on both ends of

balanced cabling.

This document describes the measurement of E2E links of two- and four-pair balanced cabling of 100 MHz

of Class D and 250 MHz of Class E using laboratory and field tester measurement procedures.

The performance of E2E links is described in ISO/IEC TR 11801-9902.

This European Standard is one of a number of documents prepared in support of European Standards and

Technical Reports on information and communication technology cabling produced by CLC/TC 215.
