DCI Copper Cable Termination 4

Question 1

What is the FIRST step a technician should perform before terminating a horizontal cable at a telecommunications outlet?

Accepted Answer

Label both ends with the port identifier

Answer

Labeling both ends before termination ensures accurate identification after the cable is dressed and the workspace is cleared.

Question 2

A punch-down tool blade is installed backwards. What is the MOST likely result?

Accepted Answer

The conductor is seated but not cut

Answer

When reversed, the cutting edge faces away from the slot, so the wire is pushed into the IDC slot but the excess is not trimmed.

Question 3

Which Cat 6A cable construction is required when installed in a plenum air-handling space?

Accepted Answer

CMP-rated (plenum) jacket

Answer

CMP (Communications Multipurpose Plenum) rated cable is required by NEC Article 800 for installation in plenum air-handling spaces.

Question 4

What does an IDC (Insulation Displacement Connector) do during termination?

Accepted Answer

Pierces the insulation to contact the conductor without stripping

Answer

IDC contacts use sharp metal edges that cut through the insulation and make direct electrical contact with the conductor.

Question 5

Which test parameter verifies that a cable link is free of split pairs AND correctly wired?

Accepted Answer

Wire map

Answer

The wire map test checks pin-to-pin continuity and identifies split pairs, reversed pairs, shorts, and opens.
