Description
A LAN (Local Area Network) tester is a tool used to verify and troubleshoot Ethernet network connections. It typically consists of a handheld device with one or more ports for connecting Ethernet cables.
The primary function of a LAN tester is to check the integrity of Ethernet cables by sending test signals through the cable and detecting any faults or issues. It can identify problems such as open circuits, short circuits, reversed wires, and crossed connections.
LAN testers often feature LED lights or a display screen to indicate the status of the cable being tested. They may also include additional features such as wire mapping capabilities, which allow users to identify the specific wiring configuration of a cable.
Overall, a LAN tester is an essential tool for network technicians and IT professionals to ensure the reliability and performance of Ethernet network connections. It helps streamline the troubleshooting process and minimize downtime by quickly identifying and resolving cable-related issues.
