Welcome to our store! 1Three Connection Methods: Two computers share one Ethernet cable simultaneously. The router and set-top box can be connected to the Internet at the same time, or the router can be used to loop back the signal to other devices. 2Connection Method: : If two computers need to access the Internet at the same time, when the router is far away from the computer, only one 8-core network cable is needed between the two rj45 splitters, but two computers are required at the same time. 3Physical Data Transmission: The RJ45 Ethernet distributor splits the original embedded Ethernet cable (8 pins) into two groups (1234/5678) and transmits data using a pure physical connection. 4Function: Specifically designed to solve weak wireless network signals and connection problems caused by insufficient wiring, such as basements, attics, remote houses, 2 or more devices online. 5Note: A pair of RJ45 splitters must be used together; one alone cannot complete the network coupling of two devices simultaneously. Simple operation, cost savings, configuration, and use. Item Type: Ethernet Splitter Material: ABS Color: Black Interface: RJ45 2 x Ethernet Splitters Customers are our top priority.
