Features: 1.[Three Connection Methods] Two computers share an Ethernet cable at the same time. The router and the set top box can be connected to the Internet at the same time or the router can be used to loop the signal back to other devices. 2.[Connection Method]: If two computers need to access the Internet at the same time, when the router is far away from the computer, only an 8 core network cable is needed between the two rj45 splitters, but two computers are required at the same time. 3.[Physical Data Transmission] RJ45 Ethernet distributor divides the original embedded Ethernet cable (8 pin) into two groups (1234/5678), and transmits data with pure physical connection. 4.[Function] specifically designed to solve network WiFi signal weak and connection problems caused by insufficient wiring, such as basement, attic, remote house, 2 or more devices online. 5.[Note] A pair of RJ45 splitters must be used together, only one cannot complete the networking of two devices at the same time. Simple operation, cost saving, configuration and use. specification:Item Type: Ethernet Splitter Material: ABS Color: Black Interface: RJ45 PackageList:2 x Ethernet Splitters Note1.
