PoE extender alfa network PDG-EX2, 802.3af compatible, extends PoE up to 100 m

The alfa network PDG-EX2 is a compact Power over Ethernet (PoE) extender compatible with IEEE 802.3af. It extends existing PoE connections up to 100 m beyond the standard single-cable reach, allowing both power and data to continue over an additional cable segment. Designed for inline installation, the PDG-EX2 enables longer-distance deployment of PoE devices such as IP cameras and wireless access points without the need for additional power outlets or complex re-cabling.

Advantages

The PDG-EX2 provides a straightforward way to extend PoE service while maintaining compatibility with 802.3af power sourcing equipment and powered devices. Its compact form factor simplifies installation in constrained spaces and inline placement, reducing the need for extra infrastructure. By preserving both data and power over extended cable runs, the extender helps maintain uninterrupted device operation and reduces installation time compared with adding intermediate PoE injectors or power sources.

Suitable for

• Extending PoE feeds to distant IP cameras
• Extending network power to outdoor or remote wireless access points
• Inline extension in existing cabling runs where additional power outlets are unavailable
• Temporary or permanent installations that require longer PoE reach without additional wiring

Key specifications

• Compatibility: IEEE 802.3af compatible PoE extender
• Extension distance: extends PoE connection up to 100 m per device
• Functionality: passes both Ethernet data and PoE power over extended cable
• Form factor: compact inline device suitable for constrained installation points

How to use

Connect the PDG-EX2 inline between the PoE source (switch or injector) and the powered device using standard Ethernet cabling. Ensure connectors are fully seated and that cable runs and terminations meet Ethernet and environmental requirements. Additional extenders can be used in series as required by the deployment, following manufacturer guidance for maximum overall link length and power budget considerations. The device functions transparently once connected and does not require separate configuration.

Usage recommendations

For reliable operation, use quality Cat5e or higher Ethernet cables and verify the total cable length and device power consumption to ensure adequate PoE budget. Avoid placing the extender in areas exposed to moisture or extreme temperatures unless protected; follow local cabling standards and safety practices during installation.
