Cabling guidelines in support of 10 GBASE-T

This Technical Report a) specifies the transmission performance for channels to support 10 GBASE-T as specified in IEEE 802.3an, b) specifies the methods to assess whether installed Class E and Class F channels meet IEEE 802.3an requirements, c) provides mitigation techniques to improve the performance of an existing installation to meet the IEEE 802.3an requirements. NOTE 1 The channel transmission performance specified in this TR is derived from IEEE 802.3an. NOTE 2 IEEE 802.3an specifies requirements beyond the frequency range specified for EN 50173 1:2007, Class E, and additional parameters to those specified for Class E and Class F cabling in EN 50173-1:2007. NOTE 3 This Technical Report does not re-specify the requirements for Class E and Class F channels of EN 50173-1:2007.

Verkabelungsleitfaden zur Unterstützung von 10 GBASE-T

Dieser Technische Bericht a) legt das übertragungstechnische Leistungsvermögen für Übertragungsstrecken zur Unterstützung des in IEEE 802.3an spezifizierten 10 GBASE-T fest, b) legt die Verfahren zur Bewertung installierter Übertragungsstrecken der Klasse E und Klasse F hinsichtlich der Einhaltung der Anforderungen von IEEE 802.3an fest, c) bietet Abschwächungstechniken zur Verbesserung des Leistungsvermögens einer bestehenden Verkabelung, damit diese die Anforderungen von IEEE 802.3an einhält. ANMERKUNG 1 Das in diesem Technischen Bericht festgelegte Leistungsvermögen der Übertragungsstrecke ist aus IEEE 802.3an abge¬leitet. ANMERKUNG 2 IEEE 802.3an legt sowohl Anforderungen fest, die über den für EN 50173 1:2007, Klasse E, festgelegten Frequenz¬bereich hinausgehen, wie auch zusätzliche Parameter zu denjenigen für Klasse-E- und Klasse-F-Verkabelung in EN 50173-1:2007. ANMERKUNG 3 Die Anforderungen für Übertragungsstrecken der Klasse E und Klasse F nach EN 50173 1:2007 legt dieser Technische Bericht nicht erneut fest.

Foreword
This Technical Report was prepared by the Technical Committee CENELEC TC 215, Electrotechnical
aspects of telecommunication equipment.
The text of the draft was submitted to vote and was approved by CENELEC as CLC/TR 50173-99-1
on 2007-11-02.
This Technical Report provides guidance whether an installed generic cabling channel meeting the
requirements of EN 50173-1:2007, Class E, will support 10 GBASE-T as specified by IEEE 802.3an.
The Technical Report also provides mitigation procedures to improve the performance of Class E
channels to the point where the application is supported. Generic cabling channels meeting the
requirements of EN 50173-1:2007, Class F, will support IEEE 802.3an up to 100 m without mitigation.
The support of IEEE 802.3an includes additional parameters and an extended frequency range
beyond Class E. Conformance of installed cabling beyond the original cabling specifications must be
determined on a case-by-case basis, and is primarily needed due to new external noise requirements.
Whether these requirements are met by a specific channel is influenced by the components and
installation practices used. As IEEE 802.3an uses frequencies above those specified for Class E of
EN 50173-1:2007, input from supplier and installer may be helpful to evaluate the performance of
installed Class E channels.
This Technical Report takes into account the design goals for IEEE 802.3an (10 GBASE-T) equipment
such as:
a) frequency signal range up to 500 MHz;
b) meet EMC limits specified for EN 55022:2006, Class A;
NOTE While IEEE 802.3an specifies an application to meet Class A on unshielded cabling, meeting Class B may require
application specific equipment and/or cabling that exceeds the requirements of this TR respectively.
–12
c) support a bit error rate of 10 ;
d) support operation over four-connector, four-pair balanced cabling.
It is expected that IEEE 802.3an will be supported by the following cabling channels specified in
EN 50173-1:2007:
– Class F channels will support IEEE 802.3an to distances of at least 100 m;
– Class E channels using screened Category 6 components and assessed and mitigated according
to the guidelines in this Technical Report will support IEEE 802.3an over distances up to 100 m;
– Class E channels assessed and mitigated according to the guidelines in this Technical Report are
expected to support IEEE 802.3an over distances from 55 m up to 100 m using unscreened
Category 6 components.
In order to provide normative cabling specifications in explicit support of IEEE 802.3an, an amendment
to EN 50173-1:2007 is under consideration. This amendment will provide new channel specifications
that will include all characteristics needed to meet and/or exceed the IEEE 802.3an requirements
(Class E and Class F ).
