PoE injector for the Gigabit range. Input voltage: 18-57 V. Supply voltage: 18-57 V. Exclusively for PoE applications. Without power supply (optional available as an accessory). Ethernet cable length up to 60 m, Ethernet speed 10/100/1000 Mbps. Compatible with all Mikrotik Routerboards. The RBGPOE is designed for Gigabit Ethernet networks. The Gigabit range has a maximum transmission rate of 1000 megabits per second. With this transmission protocol, there are no unused wires in a network cable, as would be the case with slower protocols. Therefore, the power supply must be placed under the normal data signal, making the separation of these signals more complex.
