1. Note: This product does not separate the network and is generally used to switch between networks. Therefore, it cannot be considered a router that separates network signals. 2. The RJ45 Ethernet splitter adds 2 network ports to easily switch between different computers. Only one output port can work at a time. 3. Built-in thickened PCB board ensures durability and safe signal transmission. Gold-plated core ensures optimal signal transmission. 4. RJ45 Extension Adapter: Extends your connection using 2 network cables, allowing you to connect more computers. (Only one network cable can be connected to the device at a time; do not use two network cables to connect simultaneously.) 5. This product converts network signals between 2 connected devices, effectively preventing loss caused by repeated insertion and removal of network cables. Simply click 'Disconnect' on your device to switch between the two connected devices. Product Name: 1 to 2 Way Network Splitter Colour: Black Cable length: 0.3m Connector: RJ45 male (8 pin) to female (8 pin) splitter cable. Allows two locations to share a network cable, but only one port can be used at a time; simultaneous internet access on both ports is not supported. 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 the RJ45 socket, allowing a 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.
