1 Test Description

1.1 General/Overview
With initial sample testing, the Telegärtner Labs evaluate whether an infrastructurecomponent complies with national or international standards. With this sort of testing,selected samples are usually tested before the production of a series starts.

To ensure superior product quality, the Telegärtner Labs test passive components anddevices according to the most demanding national and international standards.
With Telegärtner’s Real-time Re-embedded testing procedure,
components and devices are tested according to the demanding
category 6A specifications. However, these specifications are not
relevant for all kinds of components. Depending on the very type,they have to be tested as individual components or as part of anassembly or a link.
Telegärtner is one of the very few companies who are able to test
components without the need for baluns to be used as an adapter
between the tester and the device to be tested. Telegärtner’s direct
fixture test procedure allows the fixture of the device under test tobe connected directly to the tester. This leads to more precise andmore reliable test results than usual test procedures.

For a detailed description of the component to be tested, please refer to chapter 1.2 Device
under Test (DUT).
The standards against the component is tested are listed in chapter 1.4 Applicable Standards.

1.3 Parameters to be tested
The following parameters of the DUT were tested:a) Return LossWhen an electrical signal travels along a link, any disturbances that might occur (e.g.
transition from a cable to a connector, transition from a connector to a module (“plug tojack”)) or any changes whatsoever cause a part of the signal to be reflected at the very point
the disturbance appears. The return loss indicates how much of the signal is being reflected.
As the return loss is by convention expressed as a logarithmic ratio of the signal power
returned to the incident signal power, a high return loss value is desirable and means that
only very few power is reflected.

b) NEXTThe acronym NEXT stands for “near end crosstalk attenuation”. Crosstalk means that thesignal travelling along one pair of a cable can be detected on an adjacent pair as well, whichis unwanted. NEXT is the attenuation (“suppression”) of the unwanted crosstalk at the nearend of a link. Similar to the return loss, a high dB value of NEXT is desirable because it
indicates that only very little of signal energy leaks into adjacent signal lines.

1.4 Applicable Standards
The device was tested according to the following standard:

2 Test Setup

2.1 General/Overview
The test was conducted in the Telegärtner Lab in Steinenbronn, Germany, as described inchapter 2.2 Test Setup, in a standard lab environment.

2.2 Test Setup
The device under test was connected to the test fixture.
The fixture was connected to an 8-port network analyzer using coaxial cables.
Baluns as adaptors were NOT used.

Exploded view of the test setup. The connector body was opened to access the RJ45
connector interface. RG 188 coaxial cables connected the printed circuit board to thenetwork analyzer. A standard compliant direct probe fixture by Telegärtner terminatedthe test setup.

3.5 Test Data
The following graphical data was obtained during the tests:a) Return Loss

Return loss is measured using the direct probe fixture. The fixture is terminated with 50 Ωimpedance. Notice that this is the only way to characterize the return loss of a plug without
destroying the device under test. This means that return loss contributions from the fixture
is included in the measured signal as well. However, this is not a serious drawback, as thereturn loss contribution is small compared to that of the plug. Ultimately it is most
reasonable to compare the return loss of the plug plus fixture to the limits specified forpatch cords. As we can see there is ample headroom with respect to the limit.
