2-Pack RJ45 Ethernet Splitter Connector, Compatible with Cat7, Cat6, Cat5e Cables - Black (Two Ports Can Be Used Simultaneously) **Ethernet Splitter Connector Usage:** (1) Single Adapter Use: Can be used as an Ethernet cable extender, but only port 1 is available. (2) Paired Adapter Use: Splits one network into two, allowing two devices to be online simultaneously. See product image display for instructions. **Working Principle:** The internet splitter adapter divides an original pre-installed network cable (8 cores) into two groups (1236/4578) for data transmission. The LAN splitter is a purely physical connection and does not assign IP addresses, nor does it function as a router or switch. The signal transmission of the two groups does not interfere with each other. A pair must be used for installation. **Stable Transmission:** The network splitter Ethernet features a built-in thick, environmentally protective PCB circuit board, RJ45 eight-core standard socket, gold-plated pin core, and integrated mechanical welding for more stable signal transmission, superior contact and transmission capability, ensuring signal transmission and durability. **Safety and Stability:** Environmentally protective and flame-retardant ABS plastic shell, firm RJ45 interface, 8 TVS gas discharge tube lightning protection technology, shielding electromagnetic interference, prevents network signal loss or damage. The RJ45 splitter connector can also be used safely in the network during thunderstorms. The Ethernet cable splitter meets the performance requirements of Cat5 / Cat5e / Cat6 / Cat7 network cables. **Precautions:** The RJ45 splitter adapter is designed to solve connection problems caused by insufficient cables, using a physical tap connection to achieve network sharing in half, allowing two devices to be online simultaneously, plug and play, and requires no configuration. This Ethernet splitter adapter differs from 1-to-3 network splitters, as 1-to-3 does not allow two devices to be online simultaneously.
