DCI Copper Cable Termination 2

Question 1

When terminating a Cat 6 cable to a 110-style punch-down block, which tool setting should be used?

Accepted Answer

Cut-and-seat

Answer

The cut-and-seat setting simultaneously seats the conductor and trims the excess wire in one motion.

Question 2

What is the maximum allowed untwisting of pairs when terminating Cat 6A to a keystone jack?

Accepted Answer

13 mm (0.5 in)

Answer

TIA-568 limits pair untwisting to 13 mm (0.5 inch) for Cat 6A to maintain crosstalk performance.

Question 3

A technician notices intermittent failures on a newly terminated Cat 5e link. The MOST likely cause is:

Accepted Answer

Split pairs at the termination

Answer

Split pairs cause near-end crosstalk (NEXT) failures that appear intermittent under load.

Question 4

Which wiring standard places orange-white on pin 1 and orange on pin 2?

Accepted Answer

T568B

Answer

T568B assigns orange-white to pin 1 and orange to pin 2, making it the most common commercial standard.

Question 5

When using a modular crimping tool on an RJ-45 connector, what defect results from insufficient crimp force?

Accepted Answer

High contact resistance at the pins

Answer

Insufficient crimp force leaves the gold contacts partially seated, creating high resistance and intermittent connectivity.
