Gigabit Ethernet SplitterReidubo gigabit ethernet splitter has 1 input RJ45 port and 4 output RJ45 ports. It is designed to solve connection problems caused by insufficient cabling. You can quickly expand a single network splitter port to four, enabling four devices to transfer data simultaneously at high speeds of up to 1,000 Mbps. 1000Mbps High Speed TransmissionOur network adapter can offer a maximum speed up to 1,000 Mbps to ensure stable and reliable data transfer between devices. It allows a network connection to be split into four outputs, but with a maximum throughput of 1000 Mbps per cable set, plus there is no crosstalk between the signaling of the four cable sets. Note: We suggest that you enjoy the gigabit ethernet speed by using Cat6/7/8 Cables. The better network cable the faster network rate. Plug & PlayThe USB Powered Cable is included in the packaging.
