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.
