Extralink ACTIVE POE INJECTOR 4 PORT GIGABIT 802.3AT/AF 1 Gbps 48 V

The Extralink ACTIVE POE INJECTOR 4 PORT GIGABIT 802.3AT/AF 1 Gbps 48 V is a compact injector that adds Power over Ethernet capability to standard network switches and non‑PoE devices. It supplies 48 V PoE power across four Gigabit RJ‑45 ports while maintaining full 10/100/1000 Mbps data throughput, enabling simultaneous data and power delivery over a single cable. CE and RoHS certification ensure compliance with common safety and environmental standards.

Advantages

This Gigabit PoE injector supports IEEE 802.3at/af standards, allowing it to power a wide range of compatible devices while preserving gigabit network speeds. With four Ethernet ports, it can deliver power to multiple endpoints without requiring separate power supplies at each device. The unit’s straightforward RJ‑45 connections simplify installation, and the 48 V output provides stable power suitable for most PoE cameras, wireless access points and other networked equipment.

Suitable for

• Powering IP cameras in surveillance systems
• Supplying power to wireless access points and bridges
• Enabling PoE for network devices connected to non‑PoE switches
• Small office or retail deployments requiring up to four powered ports

Key specifications

• PoE standard: IEEE 802.3at/af compatible
• Data rate: up to 1000 Mbit/s (Gigabit Ethernet)
• Ethernet ports: 4 RJ‑45 ports
• PoE output voltage: 48 V
• Supported link speeds: 10/100/1000 Mbps

How to use

Connect the injector’s LAN input port to a network switch or router using a Cat5e or higher Ethernet cable. Plug the device(s) to be powered into the PoE output ports with standard RJ‑45 cables. Ensure the injector is connected to mains power and verify device power indicators. The injector handles both power and data delivery over the same cable, so no additional power adapters are required at the powered endpoints.

Recommendations

Use quality Cat5e or Cat6 cables to preserve gigabit performance and minimize power loss. Confirm that connected devices are IEEE 802.3at/af compatible and that their combined power draw does not exceed the injector’s per‑port or total power capabilities. Install the injector in a ventilated, dry location away from direct heat sources.
