Function: 1. 8-pin: Use an 8-pin gold-plated core to ensure signal transmission. The PCB board is embedded in conductive circuits to avoid damage to the wires. 2. Signal interference screening: Ethernet cable splitter can shield external electromagnetic signal interference and prevent internet signal damage. 3. Function: RJ45 splitter is mainly used do protect the router and facilitate connection and disconnection. With this splitter, you can connect 4 network cables into a longer cable. 4. Extended access: Each network splitter allows laptops to access do Ethernet networks in different rooms without having to pull cables from other rooms do rooms to connect do of this computer. 5. Simple operation: you connect one Ethernet cable from the wall do of the splitter cable, one from the do one computer (or laptop) and one from the do of the other computer.
