Feature:1. 8 Pin: Use 8 pin gold plated core to ensure signal transmission. The PCB board is embedded with conductive circuits to avoid damage to the conductors.2. Shielding Signal Interference: The Ethernet cable splitter can shielding external electromagnetic signal interference and prevent damage to the Internet signal.3. Function: RJ45 splitter adapter is mainly to defend the router and facilitate plugging and unplugging. 4 net cables can be connected into a longer cable through this splitter.4. Expanded Access: Either net splitter allows laptops to access ethernet in different rooms without having to pull cables from other rooms to rooms to connect to this computer.5. Simple Operation: you connect one ethernet cable from the wall to the splitter cable, one from the splitter to one computer (or laptop, and one from the splitter to the other computer.Specification:Item Type: RJ45 Ethernet Splitter CableMaterial: ABS, PCBProduct Interface: 4 x RJ45 Net PortColour: Black.Package List:1 xRJ45 Ethernet Splitter CableNote:Does not support a net cable split out at the same time to connect 2 or 3 net cable supply computer use.
