LAN testers are devices that allow a user to verify and test a connection or signal within a data cable (also known as LAN cables or high speed data cables). 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.

What is the difference between RJ45 & RJ11?
RJ45 is an 8-pin connector whereas RJ11 is only a 4 wire connector. RJ45 is used in Ethernet connections to connect computers to networks. RJ11 is more of a conventional telephone wire used to bring fibre into your house. RJ is the abbreviation of ’registered jack’.
