The video explains the benefits of the new, modular VarioKeystone connector system. The network cable can be equipped with different plug-in faces and of course with RJ 45 connectors. It allows a later performance upgrade in the network, for example, from CAT 6 to CAT 7, by simply changing the modular plug. On the basis of VarioKeystone, there is no need to lie firmly with the building wiring. The network can grow with its tasks and is future proof without the necessity for costly rewiring.
