The RJ45 Ethernet splitter offers stable transmission with excellent connectivity. It features high-quality pure copper connectors and easy-click retaining clips, ensuring a secure and corrosion-free connection. This RJ45 Ethernet splitter allows two computers to share a high-speed DSL, cable modem, or other Ethernet port without a router. (Note: This product is not a switch, so two computers cannot access the internet simultaneously. Only one output port is supported.) The RJ45 coupler is used to connect two Ethernet patch cables, extending the length of your Ethernet cable. It's ideal for extending your Ethernet connection by joining two short network cables. The RJ45 connector is fast and supports up to 10 Gb, making it suitable for connecting Cat7/Cat6 Ethernet cables. Safety and Security: Features a secure design, exquisite workmanship, a compact shell, nickel-plated connectors, and a convenient buckle for plug-and-play, driver-free installation, saving time and effort.
