This T-adapter offers the possibility to connect two end devices with only one existing connection and works as follows: Two rooms (living room with the router and study with two PCs, but only one wall socket) are each connected to a network socket, but two devices should be connected in the study. Now connect the connector doubler to the socket in the living room and route two network cables from the router into the two ports on the connector doubler. In the study, connect the second doubler to the wall socket and connect the two computers there. The connection doubler is therefore used to connect two devices via one cable (for example in the wall). Two of these adapters are always required. Other scenarios can also be covered with RJ-45 couplings (see accessories). Important: 8-wire cables must be used (Cat. 5e upwards). Only a maximum of 100MBit/s is possible. There is no PoE working over these connections.
