LAN Testers

LAN testers are used to verify 10, 100 and 1000 Base-T network. They also allow you to test and replar the network. A LAN tester consists of two units, the main unit and the Remote probe. The main unit performs the task of identifying the LAN device type i.e. whether it is a hub, switch or a PC. It also determines the speed of the LAN and the type of transmission mode. The remote probe helps in locating cable locations where a fault is present.

Cable Testers

Cable Testers are used to verify the electrical connections. They consist of a source of electrical current, a voltmeter, a switching matrix that connects the current source and the voltmeter to all of the contact points in a cable. In addition, it may also consist of a micro-controller, which automates the testing process and displays the result.
