RJ45 Network Cable Tester

The RJ45 Network Cable Tester is a tool for checking network cables fitted with RJ45 connectors, the plug type used with Ethernet networking. It is listed in the cables (other) section of this catalogue, alongside other cable-related products for security and IT installations.
Network cables can fail for many reasons: a connector crimped incorrectly, a conductor that has broken inside the sheath, or pins that are wired in the wrong order. A cable tester lets you check these points quickly, without having to swap equipment or guess where the problem lies.

Who it is for
The tester suits installers, network technicians, facilities staff and home or small-office users who work with Ethernet cables. Because the product description supplied is short, detailed specifications such as the cable types covered, the test modes available, power source and any included carry case are not stated here. Check with the manufacturer or the shop before purchase if these details matter for your job.
Using the tester
Plug each end of the cable into the tester’s ports, following the instructions supplied with the unit, and review the result. A clean result suggests the cable is wired and connected as expected. Where a fault is shown, the cable can be re-terminated, repaired or replaced, and tested again.
Summary
The RJ45 Network Cable Tester is a simple, practical tool for anyone who installs or maintains Ethernet cabling. It helps you confirm that cables are fit for use before they are relied upon in a network or security system.
