Cat 5 (Australia & Internationally) = Cat 5E (North America) 1. Permanent Links And Channels

The fundamental building blocks for a telecommunications system are the permanent
links (PL) and channels (Ch). The field testers needed for PL testing must nullify the
effects of the test leads resulting in plug connector ends that are less than 50 mm
long. The plug connector ends are also required to meet performance criteria that are
electrically “centred”. This means that, as tester manufacturers produce these
“centred” plugs, new plugs will have to be bought for use with the hand-held testers to
obtain accurate PL test results. This requirement only applies to PL testing. Channel
testing still uses the Vendor’s patch cords, which are to be left in situ after testing. The configuration of the Permanent Link and Channel is shown below.

3 tester to test for Class D performance using Cat 5 components.

Level 2e testers are no longer accepted by KRONE for full Class D performance
testing. Level 3 Testers

This accuracy level is associated with the requirements of Class E testing. Software
upgrades are the mechanism used to keep the tester up to date with accuracy and
performance requirements. These testers are complicated instruments and each
manufacturer uses different complex mathematical algorithms in their software to
achieve the necessary accuracy and performance measurements.

The following Level 3 testers are accepted by KRONE for testing of Class E
performance using Cat 6 components:

1. OmniScanner 1 & 2
2. Agilent WireScope WS350 & FrameScope FS350
3. FLUKE DSP 4000/4100/4300 & DTX-1200/1800

4. Class E Warranty Testing Using Cat 6 Components

After testers have been in the field for some time, handling and maintenance issues
can arise from extended use. The Level 3 & 4 testers need to be discussed
individually as each one has unique features.

The PL test heads contain a chip that allows the unit to zero out the effects of the test
leads there by making it an effective “50 mm lead”.

Use the generic PL test head and leads for testing the KRONE FMK and KM8 RJ45
sockets.

To test HighBand8 installations, use a N2604A-055A HighBand8 on the jumpered
fields one end, and the generic RJ45 PL test head at the TO.

To test installations using Highband 25 modules, obtain the appropriate patch cords
and test the installation as a Channel

Some installers have found that the test results improve by up to 2 dB as the tester
warms up over the first half-hour of continuous use. So if the test results seem low
initially, re-test the low runs with a warmed up tester.

Fluke DSP 4000, 4100, 4300 and DTX-1200, 1800

The difference between the 4000, 4100 and 4300 models is primarily the facility for
external memory. All units give good results for testing Class E Permanent Links and
Channels. KRONE recommends these testers undergo a regular (monthly) P-CAL
calibration. The DTX-1800 is a Level 4 tester that tests out to 900 MHz and will meet
“10GBE benchmark” and Class F performance requirements. DTX-1200 is a Level 4
tester that tests out to 350 MHz and tests for Class E performance requirements.

Class E and 10GBE Permanent Link heads must have the right Personality Module
fitted. The standard personality module PM06 comes shipped with the DSP4100,
4300 and DTX. The use of PM25 and PM01 are also acceptable.

Periodically do the self-calibration. Before the start of each new job site, then 1/week
to retain confidence in the tester readings.

Batteries Not Fully Charged
If the battery level drops below 25%, there can be false or inconsistent readings.
