This document is available as a free download from the ADC KRONE web site www.adckrone.com.au [On the right-hand side], Online Tools, Technical publications, ADC KRONE Specifications “Field Performance Testing of Copper Permanent Links” ADC KRONE AUSTRALIA Ver. 15 Field Performance Testing V15 060508 Page 1 of 11Performance Testing of Permanent Links and ChannelsThere are 3 distinct areas of cable testing; Certification, Qualification and Verification.Certification is the most rigorous of all cable testing and uses the “Pass/Fail” criteria inone of the AS/NZS 3080, ISO/IEC 11801 or TIA/EIA 568 standards. The remainder ofthis document deals with Certification Testing and it is a requirement for an ADCKRONE Warranty.Qualification testing allows technicians to troubleshoot and qualify network cabling forsuitability to a particular technology eg 100BASE-T, GBE, VoIP.Verification testing determines basic continuity functions eg wiremap, short circuits.1. Permanent Links And ChannelsThe fundamental building blocks for a telecommunications system are the permanentlinks (PL) and channels (Ch). The field testers needed for PL testing must nullify theeffects of the test leads resulting in plug connector ends that are less than 50 mmlong. The plug connector ends are also required to meet performance criteria that areelectrically “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 toobtain accurate PL test results. This requirement only applies to PL testing. Channeltesting still uses the Vendor’s patch cords, which are to be left in place after testing.The configuration of the Permanent Link and Channel is shown below.

Passive Testing With Hand-Held Field TestersThere are currently three levels of hand-held field tester: Level 2e – for testing up to Class D Level 3 – for testing up to Class E Level 4 – for testing up to Class F and the draft 10GBE benchmarkLevel 2e TestersThis accuracy level was introduced to achieve the requirements for Class D. Itincluded those parameters necessary to allow data transmission on four pairssimultaneously, as in Gigabit Ethernet. These parameters included FEXT, RL andthe calculations for ELFEXT and all POWERSUM parameters. Most level 2e testersnow only have limited support from their manufacturers.Level 2e testers are no longer accepted by ADC KRONE for full Class Dperformance testing.ADC KRONE strongly recommends that your Level 2e tester be upgraded to a Level3 tester to test for Class D performance using Cat 5 components.Level 3 TestersThis accuracy level is associated with the requirements of Class E testing. Softwareupgrades are the mechanism used to keep the tester up to date with accuracy andperformance requirements. These testers are complicated instruments and eachmanufacturer uses different complex mathematical algorithms in their software toachieve the necessary accuracy and performance measurements.The following Level 3 testers are accepted by ADC KRONE for testing Class Eperformance, using Cat 6 components:1. OmniScanner 1 & 22. Agilent WireScope WS350 & FrameScope FS3503. FLUKE DSP 4000/4100/4300. DTX-1200/1800 Level 4 testers also acceptable. LANTEK testers are not accepted for an ADC KRONE WarrantyLevel 4 TestersThis accuracy level is a requirement of Augmented Cat 6, Class EA and Class Ftesting. These testers can be used on any of the lower Class installations and stillperform at the high Level 4 accuracy.The following Level 4 testers are accepted by ADC KRONE for testing of ClassE and Class EA (Augmented Cat 6) performance for 10Gigabit Ethernet.1. Fluke DTX-1200 up to 350 MHz - OK for Class E (250 MHz)2. Fluke DTX-1800 up to 900 MHz - OK for Class EA (500 MHz) and 10GBEField Performance Testing V15 060508 Page 3 of 114. Class E Warranty Testing Using Cat 6 ComponentsAfter testers have been in the field for some time, handling and maintenance issuescan arise from extended use. The Level 3 & 4 testers need to be discussedindividually as each one has unique features.OmniScanner 1 & 2The OmniScanner 1 & 2 have the same base unit with one main difference: theOmniScanner 2 has an external memory card for storing and forwarding test results:a very handy feature to keep the tester working on-site; the OmniScanner 1 does not.The ability to test Class E Permanent Links between the two units is the same,provided they have the latest software version loaded. The testing of Class ...
