Difficulty: EasyUtilizing Hardware Testers and Packet Analyzers

A network technician needs to trace an unlabeled copper UTP cable run from a wall jack in a user's office to its corresponding port on a patch panel in the telecommunications closet. Which of the following diagnostic tools is best suited for this task?

  1. Tone generator and probe kitAnswer
  2. B
    Time Domain Reflectometer (TDR)
  3. C
    Loopback plug
  4. D
    Multimeter

Answer

The tone generator and probe kit is the correct tool for tracing an unlabeled cable run from an office wall jack to a patch panel port.
A tone generator and probe kit (commonly referred to as a toner probe) is specifically designed to trace copper cabling. The generator attaches to one end of the cable run to emit an electrical signal, and the technician uses the inductive probe near the patch panel to hear where the signal is strongest, pinpointing the correct termination.

Step-by-Step Solution

1
Identify the diagnostic objective
The task requires locating the specific physical termination of an intact copper cable run across two rooms.
The technician needs to identify which patch panel port corresponds to a specific wall outlet without disconnecting unrelated cables.
2
Select the appropriate diagnostic hardware tool
Choose a tone generator and probe kit.
The tone generator injects a high-frequency audio signal into the cable at the wall jack, and the inductive probe generates an audible tone when placed near the target wire at the patch panel.
