Full Gigabit Power: Retrofit Your Network with PoE
Do you want to install an IP camera in the garden, but there's no power outlet? Should your new WiFi Access Point be optimally placed on the ceiling, but the power cable isn't long enough? The Passive Gigabit PoE Injector is the solution. With it, you can easily and cost-effectively upgrade your existing Network with Power over Ethernet (PoE). The special feature: While simple adapters slow down your fast Gigabit Network to 100 Mbps, this model maintains the full bandwidth of 1000 Mbps. This way, you can stream 4K videos from your camera or use the full speed of your Access Point without any bottleneck.
Flexible Power Supply for IP Cameras, APs & Co.
This injector is a true multi-talent. It accepts any direct current (DC) between 12 and 48 volts. This means you can operate it with the exactly matching Power Supply for your end device. Whether 24V for many Ubiquiti and MikroTik devices or 48V for various IP Cameras and IP phones – you decide. The injector passes the voltage on one-to-one. Simply connect your existing or separately purchased Power Supply to the standard DC jack (5.5 x 2.1 mm) and reliably power your device via the network cable.
Passive PoE Explained: Simple, Direct, and Efficient
This device uses passive PoE (Mode B). This means that power is permanently supplied to wire pairs 4/5 (+) and 7/8 (-). Unlike active PoE standards (802.3af/at), no negotiation with the end device takes place. This makes the technology uncomplicated and inexpensive. Please note: Therefore, only connect devices that are explicitly designed for passive PoE with the corresponding voltage. Accidental connection of a normal laptop or PC could damage the device. For all compatible devices, however, this is an absolutely stable and proven method of power supply.
Installation in 60 Seconds: It's That Easy
Commissioning is incredibly simple and requires no technical expertise. You only need the injector, two network cables, and a suitable power supply (not included). Connect the 'LAN' port of the injector to a free port on your Router or Switch. Connect the 'PoE' port to your end device (e.g., camera). Finally, connect the power supply to the injector. The Power LED lights up, and your device will now be supplied with power and data via the network cable.
Strengths & Notes at a Glance
- Pro: Enables PoE on any non-PoE Switch.
- Pro: Maintains full 1000 Mbps Gigabit data rate.
- Pro: Extremely flexible due to wide input voltage range (12-48V).
- Pro: Super easy plug-and-play installation without configuration.
- Note: A suitable power supply (12-48V DC, 5.5x2.1mm plug) is additionally required.
- Note: As a passive injector, it is not suitable for devices that require active PoE (802.3af/at). Can damage non-PoE devices.

Frequently Asked Questions (FAQ)
What is the difference between a passive and an active PoE injector?
An active PoE injector (standard 802.3af/at) communicates with the end device before power delivery to check if it is PoE-capable. A passive injector like this one always transmits voltage without checking, which is simpler but can damage non-PoE devices.
Which power supply do I need for this PoE injector?
You need a power supply whose output voltage (e.g., 24V or 48V) matches the requirements of your end device. The power (Watt) must at least correspond to the device's consumption, and the connector must be a 5.5x2.1mm DC barrel jack.
Can I power a device over a distance of 100 meters?
No, the maximum cable length for Ethernet and PoE is limited to 100 meters. Over longer distances, data loss and a significant voltage drop can occur, which impairs the function of the end device.
Why does my Gigabit network only have 100 Mbps after connecting a cheap PoE adapter?
Cheap 100 Mbps adapters use data wires for power supply, which throttles the speed. This Gigabit PoE injector maintains the full 1000 Mbps bandwidth because it uses a technology that combines data and power without interference.
Is this injector suitable for Ubiquiti or MikroTik devices?
Yes, with a suitable 24V power supply, this injector is ideal for many Ubiquiti and MikroTik devices that use passive 24V PoE. For safety, always check the datasheet of your specific device model.
Does the LED on the injector light up even if only a network cable is connected?
No, the power LED exclusively signals the power supply. It lights up as soon as a suitable power supply is connected, regardless of the network cables.
