Extralink ACTIVE POE INJECTOR 8 PORT GIGABIT 802.3AT/AF 48V 1 Gbps

The Extralink ACTIVE POE INJECTOR 8 PORT GIGABIT 802.3AT/AF 48V 1 Gbps is an 8-port active Power over Ethernet injector designed to deliver both power and data to compatible network devices. It supports IEEE 802.3at and 802.3af PoE standards and provides 48 V PoE voltage while maintaining Gigabit Ethernet data rates up to 1 Gbps per port. The unit uses Mode A cabling and is suitable for installations that require centralized power delivery to multiple powered devices such as access points, IP cameras and VoIP phones.

Advantages

The injector combines eight Gigabit-capable PoE outputs with active power management that conforms to 802.3at/af specifications, enabling simultaneous power and data over standard Ethernet cabling. Its support for 1000 Mbps links ensures compatibility with high-speed network segments and modern PoE devices. The compact, rack-friendly form factor simplifies deployment in wiring closets or equipment cabinets while reducing the need for separate power supplies at each endpoint.

Suitable for

• Supplying power and data to wireless access points in small to medium-sized networks
• Powering IP surveillance cameras where centralized power is preferred
• Providing PoE to VoIP phones and other powered network endpoints
• Deployments that require multiple Gigabit PoE ports without PoE-capable switches

Key specifications

• Number of Gigabit Ethernet ports: 8 PoE outputs
• PoE standards supported: IEEE 802.3at (PoE+), IEEE 802.3af (PoE)
• PoE output voltage: 48 V
• Data throughput per port: up to 1 Gbps (1000 Mbps)
• Cabling mode: Mode A (power and data on pairs used for 10/100/1000 Mbps)
• Compatible link speeds: 10/100/1000 Mbps

How to use

Install the injector in a dry, ventilated location near your network switch or patch panel. Connect the injector's LAN input to a non‑PoE Ethernet switch or router using standard Cat5e or better cabling. Then connect each powered device to one of the eight PoE output ports with Ethernet cables. Ensure connected devices support 802.3at or 802.3af and verify power budgets so the total draw does not exceed the injector's capacity. Follow local electrical codes when connecting the injector to AC mains power and observe polarity and grounding requirements.

Usage recommendations

Use shielded or unshielded Cat5e/Cat6 cables for each connection and plan power distribution to avoid overloading ports. For continuous high-throughput and multiple high-power devices, allow adequate ventilation and consider ambient temperature when calculating overall power budget.
