Ethernet | Qualifier, active Lan tester and verifier

"Ethernet is Everywhere", this winged saying of a manufacturer of active network components must be accepted today without reservation. In the meantime, Ethernet has not only established itself as a transport protocol in the office world, but has also conquered a firm place in data centres, industrial applications and even in the home sector. It is therefore essential for the installer and operator of networks to have extensive testing facilities at their disposal in order to guarantee the smooth functioning of the network. Different tests are required for both installation and MACs (Moves, Adds & Changes, Add, Change), as well as for troubleshooting. Until now, several test devices for the passive and active level were required. Today, the term "Ethernet" refers to the physical interface, i.e. the transmission medium, such as cables and connectors, as well as the transmission protocol, as the basis for the well-known "TCP/IP" world, the logical functions of the network components.

Ethernet is now establishing itself as a general communication protocol outside office and home cabling in wide areas of industry and in the automotive sector, and is becoming more and more popular as a standard. Common catchwords here are IoT (Internet of Things) and IIoE (Industrial Internet of Things). Testing does not usually focus on extreme transmission speeds, but rather on special cabling configurations, mating faces and environmental conditions depending on the application.
