1. Note: This product cannot separate networks and is generally used for switching networks. Therefore, it cannot be regarded as a router that separates network signals. 2. The RJ45 Ethernet splitter can add 2 network ports to facilitate switching between different computers. Only one output port works at a time. 3. Built-in thickened PCB board, durable, ensuring signal transmission safety. Uses a gold-plated core to ensure signal transmission. 4. RJ45 Extension Adapter: The male/female adapter extends via 2 network cables to help you connect more computers. (Only one network cable can be connected to the device at a time; two network cables cannot be used to connect the device simultaneously). 5. This product can be used to convert network signals between 2 connected devices, effectively avoiding loss caused by repeated insertion and removal of network cables. When switching, simply click 'Disconnect' on your device to connect to one of the other two devices to the network. Product Name: 1 to 2 Way Network Color: Cable length: 0.3m Connector: RJ45 male (8 pin) to female (8 pin) splitter cable. Allows two locations to share one network cable, but only one port can be used at a time; two ports cannot access the internet simultaneously. Easily convert your RJ45 connection to two RJ45 cables with this network splitter cable. This RJ45 splitter cable allows you to easily increase the number of RJ45 network connections on an RJ45 socket, enabling one computer to share DSL, cable modem, and Ethernet ports. Note: This Ethernet splitter allows two computers to share an Ethernet line one at a time, but it does not support both computers connecting to the Internet simultaneously. High-quality RJ45 Ethernet network extension cable. Flexible for ease of use and turns.
