Passive PoE Adapter ALFA APOE03G-C 802.3af compliant 15.4W

The ALFA Passive PoE Adapter APOE03G-C 802.3af compliant 15.4W enables power delivery to compatible network devices over standard Ethernet cabling. This compact adapter provides up to 15.4 watts of power in an 802.3af-compatible configuration, allowing installation of wireless access points, IP cameras, or routers where a local power outlet is unavailable. The unit is designed for straightforward inline connection between a power source and a powered device, reducing the need for separate power supplies and minimizing cable clutter.

Advantages

The adapter supports 802.3af power levels up to 15.4W while maintaining a small footprint for flexible placement. Installation is simple and requires no special tools, making it suitable for quick deployments or retrofitting existing networks. By carrying both data and power over a single Ethernet cable, the adapter reduces wiring complexity and allows devices to be mounted in locations without nearby AC power. Compatibility with common PoE devices helps ensure predictable behavior in mixed-network environments.

Suitable for

• Powering wireless access points in ceilings or outdoor enclosures
• Supplying power to IP surveillance cameras where mains outlets are impractical
• Providing power to routers or network bridges installed in remote locations
• Temporary deployments, field tests, or locations with limited cabling

Key specifications

• PoE standard: 802.3af-compatible passive adapter
• Maximum power output: up to 15.4 watts
• Power delivery method: inline over Ethernet cable combined with data
• Physical form factor: compact inline adapter for easy placement
• Operating environment: suitable for indoor installations unless otherwise protected

How to use

Connect the adapter inline between the network switch or PoE injector and the powered device using a standard Ethernet cable. Ensure the powered device accepts 802.3af-level input and that cabling is rated for the installation distance. Verify connections before applying power and confirm device operation after connection. For installations that include outdoor devices, use appropriate weatherproofing and cable glands to protect the connection points.

Usage recommendations

Use the adapter with devices that explicitly support 802.3af power levels and keep Ethernet cable runs within recommended length limits to avoid voltage drop. When deploying in mixed environments, test the combination of switch/injector and powered device to confirm compatibility and stable operation.
