DCI Copper Cable Termination 5

Question 1

When installing a Cat 6 cable through a conduit shared with other Cat 6 cables, which practice reduces crosstalk?

Accepted Answer

Maintaining the cable's twist ratio and not over-bending inside the conduit

Answer

Preserving the pair twist and staying within bend radius limits maintains the cable's electrical geometry and crosstalk rejection inside conduit.

Question 2

A field technician is terminating a high-density Cat 6A panel with 48 ports. Which practice BEST prevents pair damage?

Accepted Answer

Work in small sections and re-dress cables after each block of 12 terminations

Answer

Working in small sections controls cable dress and prevents inadvertent damage to already-terminated pairs during subsequent work.

Question 3

What is the purpose of maintaining pair twist all the way into the IDC slot on a 110-style block?

Accepted Answer

Minimize near-end crosstalk at the termination point

Answer

Keeping the twist as close as possible to the IDC contact minimizes the untwisted length that acts as an antenna for crosstalk.

Question 4

Which of the following conditions would cause a 'short' fault reading between pins 3 and 6 on a cable tester?

Accepted Answer

Two conductors touching inside the connector or jack slot

Answer

A short occurs when two conductors make unintended electrical contact, typically from insulation damage or conductive contamination in a connector.

Question 5

After completing terminations on a 24-port Cat 6 patch panel, the technician should perform which test FIRST?

Accepted Answer

Wire map test on each port

Answer

The wire map test is the quickest way to confirm correct pin-out and catch wiring errors before performing more time-consuming certification tests.
