Why the “permanent link”? The true “foundation” – cabling that is

permanent and part of building infrastructure

Network equipment, patch cables and equipment cables are changed many times during the life of the the cabling infrastructure

Provide guarantee that the ‘Channel’ (permanent link plus patch cables) meets the network application requirements



Difference in Performance Specification Test limits for the Permanent Link are

defined such that adding “good” patch and equipment cords yield the channel performance

Patch cords’ effect on channel performance: The mating performance of connecting hardware

(primarily NEXT) The performance of patch and equipment cords:

Attenuation (max. 10 meters) Return Loss



The plug at the end of the adapter is the test “reference”.

• with the telecom outlet

The PL test model renders worst case NEXT test !

NEXT Variability: in connections Variability of the mated NEXT of the patch cord plug



The Fluke Networks Solution:The Permanent Link Adapter

A rugged, high-performance link interface adapter for the DSP-4X00 and OMNIScanner2

Very accurately measures the performance of an installed twisted-pair cabling system



PLA Solution for NEXT Implement the solution to test the Permanent Link

You need only one set of interface adapters and a few sets of Personality Modules

The removable 8-pin plug can be replaced with different “Personality Modules”



Cat 6 “center definition” for all wire pairs Universal solution

shielded plug to test UTP and ScTP systems

Limit the variability between PMs Increase repeatability (perceived accuracy) Provides optimum result with compliant jack



A revolutionary plug design

Implemented without cable termination and variability

Favorite of installer: Snag-free clip

Cable Identification Agree on a labeling scheme Keep it simple … fewer characters are better Ensure that the name used to save a cable test,

matches the printed label on both the patch panel and outlet

Look to the ANSI/TIA/EIA-606-A Standards for labeling guidelines (LinkWare software can help)

Test Results Management --Printed Reports

• LinkWare Software supports several alternatives to provide test results information to your customer:– Graphical color report with measured

test points over full frequency range (1 - 350 Mhz)

– Text format with worst case and worst value data

– Summary report which provides a list of the cabling links tested and key information

– Reports can be printed on paper or sent to an electronic PDF file.



Documentation Suggestions

ALWAYS save test results to a PC Make two copies of the data Print Results to paper or PDF files Do not delete results on the memory cards

until you have double-checked the results on the printed output.

Patch Cord and Spool Test Patch Cord and Spool Test SolutionSolution

How do we know whether a patch cord meets the requirements?



A Patch Cord

NEXT: Major contribution from the mated NEXT

performance of the plugs at the end of the patch cord with the jacks in the test adapters

Small contribution from the cable

Return Loss: Major contribution from the cable Small contribution from the connections



Standards Define Patch Cord Test

TIA/EIA-568-B.2-1 Paragraph 7.2.1.3: NEXT Loss

NEXT Loss of near-end connection Worst-case addition of the NEXT Loss of the remote

connection compensated for the round trip attenuation of the cable

Plus NEXT of patch cord cable Plus an allowance for reflected FEXT (=0.5 dB)

NEXT Loss test limits of patch cords is length-dependent

Very similar to latest draft of IEC 61935-2



AdapterModular Jacks

NEXT Measurement

NEXT measurement: Modular jack is the “reference”

must be selected to meet the Cat 6 component-level definition These jacks can also be used to certify Cat 5e patch cords
