Chapter 2: Certify Twisted Pair Cabling

How to Certify Patch Cords

To certify patch cords, you must use the DSX-PCxx Patch Cord

Adapters and the correct patch cord test limit. You cannot use

channel adapters and test limits to certify patch cords because

channel tests do not measure the performance of the patch cord

plugs.

To purchase a DSX-PCxxS Patch Cord Adapter Set, contact an

authorized Fluke Networks distributor.

Twisted Pair Autotest Results

The tests listed below apply to twisted pair cabling.

Note

Some tests are not included in some test limits.

 Wire map

 Resistance

 Resistance unbalance in a pair

 Resistance unbalance between pairs

 Length

 Propagation delay

 Delay skew

 Insertion loss (attenuation)

 Impedance

 NEXT (near-end crosstalk)

 PS NEXT (power-sum near-end crosstalk)

 ACR-N (attenuation to crosstalk ratio at the near end)

 PS ACR-N (power-sum attenuation to crosstalk ratio, near

end)

 ACR-F (attenuation to crosstalk ratio at the far end)

 PS ACR-F (power-sum attenuation to crosstalk ratio, far end)
