6.8.3. Return Loss
6.8.4. DC Resistance.
Single and Multi-Port Jack Assemblies
Connector return loss is a measure of the degree of impedance matching between the
cable and connector and is derived from swept frequency voltage measurements on short
lengths of 100 Ω twisted-pair test leads before and after inserting the connector under test.
A balanced input signal is applied to a connector pair while signals that are reflected back
due to impedance discontinuities are measured at the same port from which the signal is
applied. The same set-up that is used for NEXT loss measurements is also used for
return loss, except that only a single connection is made to the network analyzer.
Because the return loss characteristics of category 3 connector hardware are not
considered to have a significant effect on the link performance of category 3 UTP cabling,
return loss requirements are not specified for category 3 connectors.
For category 4 and 5 connectors, the minimum return loss shall be 23 dB or greater for
frequencies between 1 and 20 Mhz. For frequencies from 20 to 100 Mhz, category 5
connectors shall exhibit a minimum return loss of 14 dB or greater. These return loss
values are chosen to limit peak reflected voltage to 7% or less up to 20 Mhz and to 20%
or less from 20 to 100 Mhz.
The DC resistance between the input and output connections of the connecting hardware
(not including the cable stub, if any) used for 100 Ω cabling shall not exceed 0.3 Ω when
tested in accordance with ASTM D 4566.
NOTE: DC resistance is a separate measurement from the contact resistance
measurements required in normative Annex A. Whereas DC resistance is measured to
determine the connector’s ability to transmit direct current and low frequency signals,
contact resistance measurements are used to determine the reliability and stability of
individual electrical connections.
