Description

Ethernet CAT Tester is a handheld diagnostic device used to test and verify the continuity, wiring accuracy, and performance of network cables such as Cat5, Cat5e, Cat6, Cat6a, and Cat7 Ethernet cables. It helps technicians, installers, and network users quickly detect wiring faults like open circuits, short circuits, crossed wires, reversed pairs, and split pairs.

The tester typically consists of a main unit and a detachable remote unit, allowing users to test cables installed across long distances such as walls, ceilings, or network racks. LED indicators or a digital display clearly show the status of each wire pair, making troubleshooting fast and accurate.

Most Ethernet cable testers are compact, battery-powered, and easy to operate, making them ideal for network installation, maintenance, office setups, home networking, and IT support work. Some advanced models also measure cable length, signal strength, and shielding integrity for more detailed network diagnostics.
