【1 to 4 RJ45 Port Connection】This Ethernet splitter allows you to easily expand a network connection by splitting it from one port to four, enabling four devices to simultaneously use the same Ethernet line. Say goodbye to repeatedly plugging and unplugging network cables and enjoy a smooth and stable internet experience. If your router or switch lacks RJ45 ports, this RJ45 splitter is the ideal solution to increase your bandwidth. 【1000 Mbps Gigabit Speed】With speeds up to 1000 Mbps, this RJ45 hub ensures fast and stable transmission for HD streaming, online gaming, and file transfers. Note: The four devices share a total bandwidth of 1000 Mbps, while a single device can achieve 1000 Mbps. Each output transmits the signal without interference.

Product Name: 1 to 4 Ethernet LAN Switch Number of Ports: 4 ports Transmission Speed: 1000 Mbps Transmission Distance: Up to 100 m Please note: Equipped with a USB power cable, it can simultaneously provide power and network connection. Cannot be used without power. 1. This 1x4 Ethernet splitter allows a router or Ethernet switch to provide 4 simultaneous network outputs. (NOTE: USB powered, cannot be used without connection). 2. The RJ45 splitter is mainly used to solve the problem of homes with only one built-in network port. The maximum transmission distance is up to 100 m. Use the USB power cable to allow 4 computers to share the same Ethernet line simultaneously with a physical splitter method. 3. The RJ45 splitter can split one network cable into 4 outputs; the speed of each group of cables (1, 2, 3, and 4) can reach up to 1000 Mbps. In addition, signal transmission between the 4 groups of cables causes no interference.
