LAN Tester

LAN Tester, also known as a network cable tester, is a diagnostic tool used to verify the performance and reliability of network cables such as Cat5, Cat5e, Cat6, and Cat6a Ethernet cables. It helps detect issues like open circuits, short circuits, miswiring, and continuity problems in wired networks.

The tester typically consists of a main unit and a remote unit. When a cable is connected, it sends signals through each wire pair and indicates the results via LEDs or digital displays. Advanced LAN testers can also measure cable length, identify specific wire pairs, and detect signal quality issues.

LAN Testers are widely used by network technicians, IT professionals, and installers to ensure accurate cable termination, maintain network integrity, and troubleshoot connectivity problems efficiently. They are essential for reliable wired network setup in offices, data centers, and homes.
