4XEM 2-to-1 splitter cable is an ideal device to increase the number of RJ-45 network connections on an RJ-45 outlet. This allows for two Ethernet signals to go through a single CAT6 wire. Being a technical product, this splitter is designed to greatly increase your Ethernet installations. On one end of the installation, this splitter can connect two patch cables from a hub to a single patch panel. It is important to note that this product is not designed to connect one single Ethernet connection to two separate computers/devices—you would need to use a hub connection for that.
