SMLIGHT PoE splitter 100Mb – Ethernet + USB-C/DC

The SMLIGHT PoE Splitter 100Mb USB-C is a practical networking accessory designed to power devices over Ethernet that do not natively support PoE (Power over Ethernet), but feature both USB-C power input and Ethernet connectivity. The device converts IEEE 802.3af and IEEE 802.3at PoE power into a stable 5V USB-C output while simultaneously maintaining a 10/100 Mbps Ethernet network connection. This allows both power and data to be delivered through a single Ethernet cable.

The splitter is especially recommended for IoT environments where providing a separate power outlet would be difficult or costly. It is an ideal solution for powering Home Assistant servers, Raspberry Pi systems, Zigbee coordinators, network gateways, SMLIGHT adapters, and other USB-C powered devices.

Automatic PoE detection ensures safe operation by activating power delivery only when a compatible PoE source is detected. The integrated 2.5 kV galvanic isolation increases operational reliability and provides protection against electrical interference.

Thanks to its compact design, the splitter can easily be installed in junction boxes, rack cabinets, multimedia cabinets, or other confined spaces. It helps create a cleaner, more reliable, and easier-to-manage smart home and network infrastructure.
