LAN testers are devices that allow a user to verify and test a connection or signal within a data cable. The types of tests include whether the cable is set up correctly, connected, the strength or speed of the signal being sent through the cable.

Usually made up of 2 sections or 2 boxes, a network cable tester will have a receiver and a transmitter. A cable is then connected directly or with connectors to both for testing. Once the tester is switched on a signal or data is sent via the cable and a report or the results are shown on the receiver. Receivers comes in a variety of types, shapes and sizes and therefore the results may vary in the way they are displayed. Some have LED's, some show patterns in lights and some different colours. The tester instruction manual will show what the results mean but some testers help determine the connection speed and detect problems.
