This Gigabit RJ45 Ethernet splitter is primarily used to solve connection problems caused by insufficient cabling. It uses a USB power supply cable and supports two computers sharing one Ethernet cable simultaneously using the physical tapping method. : Both female ports work simultaneously. Aluminum Material: Durable and not easily damaged. Built-in thick and environmentally friendly PCB circuit board, RJ45 8-pin standard connector, gold-plated pin core, integrated mechanical welding for more stable signal transmission. 1000 Mbps Transmission Speed: Ethernet splitter 1 to 2 ways dual female port LAN Ethernet cable, with a maximum throughput of 1000 Mbps per cable set (1 and 2), plus there is no crosstalk between the signaling for the two cable sets. (: This speed figure is the maximum value for the circuit set; the actual speed depends on the connected device.) Wide Compatibility: RJ45 8P8C LAN Internet Splitter Connection Extender is suitable for Cat8 Cat7 Cat6 Cat5 Cat5e network Ethernet cables, which can be used with ADSL, hubs, switches, TVs, set-top boxes, routers, wireless devices, computers, and more.
