RJ45 CAT6 CAT5 8 Pin Ethernet Cable Splitter 2 in 1 Network Extension Adapter 1. You can easily convert an RJ45 connection into two RJ45 sockets, allowing two computers to share high-speed DSL, cable modem and Ethernet ports without a router. 2. This RJ45 1 to 2 RJ45 Ethernet splitter solves the problem of pulling the connection line back and forth. Compatible with Cat5Cat5eCat6Cat7. 3. Material: 2mm thick PCB board embedded in the conductive circuit to avoid damage and leakage to the conductor. Ensure longer service life. 4. Pure copper gold-plated pins with eight cores: excellent connection and transmission performance. The fixed RJ45 female interface can shield external electromagnetic signal interference and prevent Internet signal damage. The screw hole panel can be fixed on the wallboard. 5. A single RJ45 Ethernet splitter cannot allow two computers to access the Internet at the same time. It only supports alternating access to the Internet. When one interface is connected, the other interface needs to remain disconnected. Its main function is to avoid repeated plugging and unplugging of network sockets.
