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.
This document describes the measurement of the three cabling structures specified in EN 50173-20 which
verifies the performance of their terminating connectors.
This measurement includes the transmission performance of the connector components which terminate the
cabling under test.
This document 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.
1 Scope
This document specifies the measurement of two- and four-pair balanced cabling of the following cabling
configurations specified in EN 50173-20:
a) end-to-end (E2E) link Class D, E and E ;
A
b) modular plug terminated links (MPTLs) of Class D, E, E , F, F and of Class I and II;
A A
c) direct attach cabling of Class D, E, E , F, F and of Class I and II.
A A
The free connectors which terminate two and four pairs in field and laboratory conditions are included.
This document specifies laboratory and field measurement procedures. The requirements for accuracy to
measure cabling parameters identified in EN 50173-20 are provided in IEC 61935-1 and EN 61935-2.

4 Conformance
For a measurement of E2E link, MPTL or direct attach cabling to conform to this document, the following
applies:
a) The configuration, structure and transmission performance limits shall conform to the requirements of
EN 50173-20;
b) The testing shall be undertaken in accordance with Clause 7;
c) The test head shall meet the requirements of Clause 8.
5 Transmission limits of E2E link, MPTLs and direct attach cabling
The cabling under test shall comply with the transmission limits for the designated category in EN 50173-20
when tested with the corresponding test head as described in Clause 8 and the transmission limits of all lower
categories.
E2E link testing should be used to provide assurance of installed cabling terminated at both ends in accordance

EN 61076-3-104, EN 61076-2-109 or EN 61076-3-110.
MPTL testing should be used to provide assurance of installed cabling terminated at both ends conforming to
EN 50173-20.
Direct attach cabling testing should be used to provide assurance of installed cabling terminated at both ends
in accordance with the EN 60603-7 series, EN 61076-2-101, EN 61076-2-109, EN 61076-3-104 and
