1000Mbps Active Ethernet Port Expander

This 1-to-4 Ethernet expander measures 9.5 × 5.5 × 2.5 cm and weighs 85 g. Its housing is made from flame-retardant ABS plastic, with gold-plated RJ45 contacts for corrosion resistance and reliable contact. It supports 1000 Mbps full-duplex transmission and works with Cat 5/5e/6/7/8 cables. A 5V USB power source is required for operation — the device draws less than 0.5A and includes a 1.2 m micro-USB cable. Simply connect your primary Ethernet line to the input port, then link up to four wired devices (PC, laptop, IPTV box, game console, or IP camera). Its compact, low-noise design makes it suitable for quiet zones such as home libraries, recording studios, and medical offices where fanless, silent operation is essential.
