Power over Ethernet (PoE) has revolutionized the way network devices are powered, especially in situations where a traditional power source is not easily accessible. The MikroTik RBPOE Injector is a simple yet powerful device designed to deliver both power and data to compatible MikroTik products through a single Ethernet cable. Compact, affordable, and easy to deploy, this injector is a popular solution for powering MikroTik routers , access points, and other compatible equipment without the need for additional adapters or complex wiring.
In-Depth Overview of the MikroTik RBPOE Injector
The MikroTik RBPOE Injector is a passive PoE injector specifically designed to complement MikroTik’s wide range of networking equipment. This device is ideal for those who want to power MikroTik devices remotely without relying on direct electrical connections. It takes in a regular power input through a DC jack and combines it with the Ethernet signal, outputting both through a standard RJ45 port to the end device.
This injector belongs to MikroTik’s reliable line of power accessories, designed with simplicity and efficiency in mind. While it’s called “passive,” meaning it doesn’t negotiate power with the end device like 802.3af/at standards do, it provides a consistent voltage suitable for compatible MikroTik devices.
Key Features of MikroTik RBPOE Injector
- Passive PoE Support: Delivers unregulated power over Ethernet, compatible with MikroTik devices requiring passive PoE.
- Compact Design: Small and lightweight, making it easy to install in tight spaces or behind racks.
- Plug-and-Play Functionality: No configuration required. Simply connect the power adapter and Ethernet cables.
- Wide Compatibility: Works with many MikroTik models, including routers, access points, and CPE devices.
- Cost-Effective Powering Solution: Enables centralized power distribution without costly infrastructure upgrades.
Benefits of Using the MikroTik RBPOE Injector
Using a MikroTik RBPOE Injector offers several benefits:
- Simplified Installation: Reduces the need for multiple power outlets or complex cabling. A single Ethernet cable carries both data and power to the device.
- Reduced Infrastructure Costs: Especially useful for outdoor or ceiling-mounted devices where running separate power lines would be expensive or impractical.
- Flexibility in Device Placement: Users can install their MikroTik devices in locations previously inaccessible due to power limitations.
- Reliable Performance: The injector provides stable power delivery suitable for all compatible MikroTik passive PoE devices.
- Improved Network Management: With centralized power, it’s easier to manage and maintain a clean and organized network environment.
Common Use Cases for MikroTik RBPOE Injector
- Home and Small Office Networks: Powering MikroTik hAP or mAP series routers without cluttering the environment with additional cables.
- Outdoor Installations: Supplying power to MikroTik wireless CPE devices like the LHG or SXT series.
- Retail and Hospitality: Discreetly powering ceiling-mounted MikroTik access points.
- IP Surveillance: Providing power to compatible MikroTik devices used for surveillance or remote monitoring.
How to Use the MikroTik RBPOE Injector
- Plug your DC power adapter into the injector’s DC input port.
- Connect an Ethernet cable from your router or switch to the injector’s Data In port.
- Connect another Ethernet cable from the Data + Power Out port to your MikroTik device.
- Once connected, the device should power on automatically if it supports passive PoE and the voltage is appropriate.
Note: Always check the voltage compatibility before connecting. The RBPOE Injector does not regulate or negotiate power like active PoE injectors.
Choosing the Right Power Adapter
When using the RBPOE injector, the choice of power adapter is crucial. MikroTik recommends using only certified power adapters to avoid damaging your equipment. Voltage should match the specifications of the target device—commonly 24V or 48V for MikroTik routers and antennas.
Tip: For longer Ethernet cable runs, a higher voltage (like 48V) helps mitigate power loss over distance.
When Not to Use a Passive PoE Injector
Not all devices support passive PoE. Using the RBPOE injector with incompatible equipment can result in permanent damage. Avoid using this injector with:
- Devices that require 802.3af/at PoE negotiation.
- Non-MikroTik or third-party devices unless explicitly listed as passive PoE compatible.
- Routers with onboard power protection expecting a regulated power source.

Frequently Asked Questions (FAQ)
1. What devices are compatible with the MikroTik RBPOE Injector?
It works with MikroTik devices that support passive PoE, such as hAP, mAP, LHG, SXT, and Groove series.
2. Is the RBPOE injector Gigabit-compatible?
No, it only supports 10/100 Mbps connections. For Gigabit PoE, consider the RBGPOE model.
3. Can I use it with a 48V power adapter?
Yes, if the target device supports 48V passive PoE input. Always check your device’s voltage requirements.
4. Is this injector compliant with 802.3af or 802.3at PoE standards?
No, it’s a passive PoE injector and does not support active PoE negotiation.
5. What is the maximum cable length supported?
For 24V power, it’s recommended to keep cable runs under 30 meters. Higher voltage (48V) can go further.
