The Planet POE-E201 is a IEEE 802.3at Power over Ethernet (PoE) extender designed to extend the reach of both Gigabit Ethernet data and PoE power beyond the standard 100-meter limit. It effectively doubles the distance, allowing for connections up to 200 meters, and can be daisy-chained for even greater distances. The device automatically detects and protects PoE equipment and requires no external power supply
