1. LAN splitter quality: The Ethernet splitter is made of environmentally friendly ABS material, which provides above-average resistance to mechanical damage and offers both heat resistance and low temperature resistance. The RJ45 splitter is 24-karat gold-plated, protecting the RJ45 connector from corrosion and oxidation, making the splitter safer and more convenient to use. 2. LAN splitter design: If you frequently use computers and TVs in three different rooms, this RJ45 splitter can connect three network cables to a longer cable.

This design improves network usability by giving you a practical LAN cable splitter connection. 3. Important note: This splitter splits one Ethernet line to three computers, but does not support simultaneous Internet access for all three. 4. Function: The RJ45 splitter adapter is mainly used to defend the router and to make plugging and unplugging easier. This splitter allows 3 power cables to be connected to a longer cable.
