## Long description

Extralink 1 Port PoE Injector is a passive PoE injector designed to deliver power to a single Ethernet device over a standard Cat5/Cat6 cable. It provides a Fast Ethernet connection (10/100 Mbps) while injecting 48 V power onto the cable pairs so the powered device does not require a separate power supply. The compact, lightweight unit connects between an unpowered Ethernet port and the powered device using RJ45 connectors.
Advantages
The Extralink PoE injector combines data transmission and 48 V power delivery in a single inline unit, allowing simple installation without modifying existing network switches. Its two RJ45 ports separate data input and PoE output, and the passive design keeps the device compact and energy-efficient. The injector’s small size and 3 g weight make it easy to place in constrained or remote locations.
Suitable for
 Powering a single PoE-enabled IP camera
 Supplying power to a wireless access point or bridge
 Powering network devices in locations without nearby power outlets
 Small office and home network setups requiring a single PoE feed

How to use
Connect the injector’s data input RJ45 port to your network switch or router using an Ethernet cable. Connect the injector’s PoE output RJ45 port to the PoE device (for example, an IP camera or access point). Ensure cables are properly seated and the powered device supports passive 48 V PoE on pairs 4,5 (positive) and 7,8 (negative). The injector requires no additional configuration.
Usage recommendations
Use quality Ethernet cables (Cat5e or higher) for reliable power and data delivery, and verify that the powered device accepts passive 48 V on the specified pairs before connecting. Avoid using the injector with devices that require IEEE 802.3af/at negotiation unless they explicitly support passive PoE at 48 V.
