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.
In the event that links or assemblies must be investigated using field test equipment,
Telegärtner is using the state of the art equipment from all market-leading equipment
manufacturers. To ensure that the most current equipment and the test procedures areemployed, Telegärtner is in regular exchange with the R&D departments of all thoseequipment manufacturers.
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.

Notice that category 6A specifications according to ISO/IEC 11801 Ed. 2.2 apply only to single
RJ45 jacks and are not intended to be used for RJ45 jack-jack couplers as well. A generalconsensus reached between technical experts from the ISO/IEC is, that any component for
which no direct test procedure was agreed can only be tested indirectly in the sense that thepresence of such a component in a transmission channel must not deteriorate the channel
performance compared to an equivalent channel without such a component.
Following that doctrine the standard Telegärtner lab procedure for testing jack-jack couplers
is to test against a 4 connector channel using two couplers.

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 a link resembling the typical horizontal cabling.
The whole link was tested with a field tester Fluke DTX-1800 with channel link adapters as isappropriate on construction sites.

Test setup with Fluke DTX-1800 with all components and couplers shown.
The length of the S-FTP AWG23 solid cable is 15 m. All patch cords are AWG27/7 stranded
cable with a length of 5 m.

The return loss test result of all pairs shows significant headroom with respect to thespecified values. There are neither visible artifacts nor deterioration patterns which could be
attributed to the presence of the couplers.

The NEXT test results of pair combinations 12-78, 12-36, 12-45, 36-78 and 45-78 are well
below the specified values. This is in line with the notion that cross talk between the most
distant outer pairs 12 and 78 as well as the cross talk between inner pairs 36 or 45 to theouter pairs 12 or 78 should be small because of the larger separation of those pairs. Thecross talk between the split inner pair 36 and the most inner pair 45 is also as expectedsignificantly larger but also below the specified limit values.

4 Test Results

4.1 Summary of the Test Data
The return loss test result of all pairs is better than the specified values.
The NEXT test result of all pair combinations, including the innermost pair combination 3645 is in line with the specified values.

4.2 Conclusion/Recommendations
The results of the test, parameters NEXT and Return Loss tests can be regarded as

PASS
As couplers are not part of the current issue of ISO/IEC 11801 Ed. 2.2 they should not beregarded as an individual component but only be used as part of the entire link, e.g. in thecross-connect or the consolidation point.
Furthermore, it is a general principle laid out in ISO/IEC 11801 that the attenuation of thelink is a critical parameter which influences significantly Return Loss as well as cross talkNEXT/FEXT. The underlying mechanism is that a too large reflected signal powersuperimposes on DUT signal power and thus leads to systematically too large or to small
results. This is taken into account in the ISO/IEC 11801 by requiring a minimum insertion lossof 3dB for valid Return Loss measurements and of 4dB for valid NEXT measurements.
Therefore Telegärtner recommends for a valid link test set-up a minimum length of 15m fortypical cabling. For short links with a length below 15m which in general are not covered bystandard test procedures according to IEC 11801 a different measurement methodologyshould be considered. E.g. for short links with multiple segments it is a generally accepted
test approach to resort to the IEC test procedures for patch cords.
