GBT-12-1U 2.5G 802.3BT Type 4 Active PoE++ Injector Up to 90W Max Output 1U Rackmount High-power Midspan Injector for PoE lighting PTZ Cameras

The GBT-12-1U is a high-power 12-port 2.5 Gigabit Active PoE++ injector, engineered for next-generation network deployments requiring both higher bandwidth and higher power density.

The GBT-12-1U supports IEEE 802.3af/at/bt compliant Active PoE, enabling automatic power negotiation and safe operation with a wide range of powered devices. This ensures reliable delivery of power only when a compatible device is detected—reducing the risk of damage and improving deployment flexibility.

With support for 2.5Gbps data rates, this injector is ideal for modern high-throughput applications such as WiFi 6/6E access points, high-resolution IP cameras, and bandwidth-intensive edge devices.

Its 1U rackmount form factor enables clean and scalable integration into data cabinets and network racks.
