The MikroTik RBPOE is a compact, cost-effective passive PoE injector engineered to supply DC power to remote RouterBOARD units and network devices over 10/100 Mbps Ethernet cables. By utilizing unused Ethernet wire pairs (4, 5 for positive; 7, 8 for negative) to transmit electrical power alongside standard data streams, it simplifies remote hardware installations on roofs, towers, and outdoor poles.
The cable adapter features a female 2.1 mm DC barrel jack for plugging in standard power adapters, a female RJ45 jack for receiving data from local switches or routers, and a male shielded RJ45 connector for running combined power and data directly into the target device. It supports power input from 10 V up to 28 V DC (up to 2 A current), making it ideal for standard 12V and 24V passive PoE RouterBOARD hardware.
Its lightweight molded design minimizes strain on equipment Ethernet ports while providing grounded shielding to reduce electro-static discharge (ESD) risks. Designed for simple plug-and-play operation without requiring configuration, the RBPOE is an indispensable accessory for wireless internet service providers (WISPs), outdoor CPE installations, and compact network deployments.
