Tools required for network cable testing

Network cable tester

This device checks the correct wiring order and whether the cable is terminated to standard. It can detect open circuits, shorts, and wire misplacements, and some models estimate cable length and locate faults.

RJ45 crimp tool

This tool is used to install RJ45 connectors on cables and ensures proper wire placement and full contact with connector contacts.

Good quality reference cable

A healthy reference cable is useful to verify tester accuracy and to compare test results.

Punch-down tool

Used to terminate cables in keystones or patch panels with correct wire seating.

Multimeter

A multimeter measures electrical quantities and can help check continuity and detect open circuits in specific scenarios. It is not a replacement for a network tester but can assist in initial diagnosis.

Tone generator and probe

To trace cable paths among many cables, a tone generator sends a signal and the probe detects the path or other end.

Advanced tester or Fluke

Professional testers assess structured cabling with parameters such as signal loss, noise, interference, distance, and standard compliance.

Cable loop tester

A loop tester placed at the end of a cable helps verify complete path testing and speeds up the process.

Flashlight and visual tools

Low-tech checks like bending, insulation wear, or crushed jackets can be performed visually.

Cable labeling check

Labeling aids in identifying source and destination, speeding up troubleshooting.
