POE Injector 4-Port Gigabit Passive PoE Injector

The POE4PG is a compact four-port passive PoE injector designed to combine Gigabit Ethernet data and DC power for several compatible network devices. It provides eight 1 Gbps RJ45 interfaces arranged for four independent connections, with a LAN input and a PoE output for each channel. This allows an existing non-PoE switch or router to serve compatible access points, wireless CPE units, IP cameras, and other Ethernet equipment without adding a separate injector for every device. Gigabit support helps preserve network throughput when the connected equipment and cabling also support data rates of up to 1 Gbps.

Measuring 115 × 45 × 25 mm, the injector offers a space-efficient option for network cabinets, technical panels, and compact installations. It is specified for operation from 0 °C to 40 °C and can power up to four passive PoE devices from one external DC source. The power supply is not included and must be selected separately. Since the POE4PG uses passive PoE, it should only be connected after confirming that the voltage, polarity, available current, and PoE pin arrangement match the requirements of every powered device. Compatibility with IEEE 802.3af, 802.3at, or 802.3bt should not be assumed, as passive PoE does not provide standards-based power negotiation before voltage is applied.
