What is the primary purpose of a tone generator and inductive amplifier (toner/probe) set in cabling work?
Answer: To trace and identify cables without cutting into walls
A tone generator sends a signal through a cable and the inductive amplifier (probe) detects it through walls and conduit, allowing installers to trace and identify specific cables.
Which cable stripping technique is recommended to avoid damaging the conductors inside a UTP cable?
Answer: Use a cable stripper set to the correct depth to remove only the outer jacket
A properly adjusted cable stripper removes only the outer jacket without nicking the insulation or conductors beneath, which could cause continuity faults.
When using a cable certification tester, what does a 'FAIL' result on the 'Return Loss' parameter indicate?
Answer: Too much signal is being reflected back toward the source due to impedance mismatches
Return Loss measures the amount of signal reflected back due to impedance discontinuities; a FAIL means excessive reflection that will degrade network performance.
What type of saw is most appropriate for cutting a clean rectangular opening in drywall for a low-voltage mounting bracket?
Answer: Oscillating multi-tool or drywall saw
An oscillating multi-tool or drywall keyhole saw gives controlled, clean cuts for outlet openings without the risk of overcutting or damaging adjacent materials.
A fish tape becomes kinked and difficult to retract. What is the correct corrective action?
Answer: Straighten the kink carefully by hand and store the tape properly coiled in the reel
Kinks in fish tape can be carefully straightened and the tape stored properly; severe kinks may require the tape to be replaced to prevent breakage during use.
Which tool is specifically designed to punch down conductors into 110-style IDC (Insulation Displacement Connector) blocks?
Answer: 110 punch-down tool
The 110 punch-down tool is designed with a blade that seats conductors into 110-type IDC slots and trims excess wire in one motion.
What is the function of the 'Cable ID' or 'Remote' unit included with most cable continuity testers?
Answer: It terminates the far end so the main unit can verify pin-to-pin continuity across the full cable length
The remote/ID unit is placed at the far end of the cable and provides termination so the main tester can send signals through each conductor and verify correct pinout and continuity.
