• Durable Construction
  Built to endure both indoor and outdoor conditions when used within enclosure systems, the RBPOE withstands professional deployment environments.
• RJ45 Input and Output Interface
  Data input through one RJ45 port and a combined power/data output through the second RJ45 port keep operation straightforward.
• 2.1mm DC Jack Input
  Users can connect a wide range of DC power supplies, ensuring compatibility with various MikroTik devices.
• Cost Efficient Power Delivery
  Its simplicity ensures affordability without sacrificing reliability.
• Universal Usage with Passive Compatible Devices
  Any MikroTik device that supports passive PoE can be powered using the RBPOE Injector.

Benefits of Using the MikroTik RBPOE Injector

The benefits of the MikroTik RBPOE Injector extend far beyond its small footprint. Some of the most notable advantages include:

Highly Reliable Power Transmission

The RBPOE provides a direct, loss minimized flow of electrical power over Ethernet. Because it uses passive PoE, there is no complex handshake or voltage conversion, minimizing the risk of failure and maximizing predictability.

Reduced Cable Clutter

By merging power and data into one Ethernet cable, installers can drastically reduce cable congestion. This is especially valuable in racks, ceilings, remote towers, or compact interior spaces.

Ideal for LongDistance Installations

Passive PoE allows power to travel over longer distances without intelligent negotiation slowing things down. Outdoor deployments or rooftop antennas greatly benefit from this simplicity.

Affordable Networking Efficiency

Despite its reliability and robust construction, the RBPOE remains costeffective. This makes it an excellent choice for bulk installations, campus networks, and ISP deployments.

Compatible with a Wide Range of MikroTik Devices

Designed primarily for MikroTik’s extensive lineup of passive PoE devices, the RBPOE provides a reliable power source for routers, access points, CPE units, and more.

MRHPELevel Longevity

Even with its simplicity, the RBPOE is built using MRHPE grade standards, ensuring a long operational lifespan and dependable power delivery under challenging conditions.

Common Use Cases for MikroTik RBPOE Injector

This injector thrives in a wide range of scenarios. Some popular applications include:

Outdoor Wireless Access Points

Ideal for supplying power to devices mounted on roofs, poles, or towers without running an additional power cable.

CPE Installations for ISPs

Service providers often deploy the RBPOE in large numbers to power CPE devices installed at customer premises.

Home and Office MikroTik Routers

Simple, compact, and affordable—perfect for powering compatible MikroTik routers in a minimal cabling environment.

Surveillance Networks

Passive PoE cameras often rely on injectors like the RBPOE for consistent voltage delivery.

Temporary or Mobile Installations

Event setups, mobile stands, and popup network solutions benefit from the injector’s small size and ease of use.

How to Use the MikroTik RBPOE Injector

Using the RBPOE Injector is straightforward:

1. Connect Data Source
Plug the Ethernet cable from your network switch or router into the RJ45 input labeled “LAN” or “Data In.”

2. Attach the Power Supply
Insert your DC power adapter (e.g., 24V) into the 2.1mm DC jack.
Ensure that the adapter voltage matches the needs of your powered device.

3. Connect Output Cable
Plug another Ethernet cable from the injector’s RJ45 output into the target device’s PoE port.

4. Verify Power Delivery
Once connected, the powered device should boot up immediately.

5. Secure Cabling
Organize cables to prevent tension, displacement, or accidental disconnection.

Because no configuration or software is involved, the RBPOE is a plugandplay accessory in the truest sense.

Choosing the Right Power Adapter

Since the injector is passive, the voltage you supply is the voltage your device receives. Therefore, selecting the correct power adapter is essential.

Guidelines for Choosing the Proper Adapter:

• Match the voltage requirement of your MikroTik device (commonly 12V, 24V, or 48V).
• Choose an adapter with sufficient amperage to support power draw under load.
• Ensure the plug is 2.1mm to fit the RBPOE injector’s DC jack.
• Use highquality, regulated power supplies to avoid electrical instability.

Using the wrong voltage can damage connected devices, so it is critical to verify compatibility before powering up.

When Not to Use a Passive PoE Injector

While the RBPOE is highly useful, there are situations where it is not appropriate:

Avoid Using Passive Injectors When:

• Your device requires 802.3af/at/bt active PoE.
  These standards require intelligent negotiation; the RBPOE cannot provide it.
• You are unsure of voltage compatibility.
  Passive PoE passes voltage directly—no protection, no conversion.
• The Ethernet cable runs are excessively long and may cause voltage drop at high current draw.
• Your device explicitly warns against passive PoE.

In any of these cases, an active PoE injector or switch is the safer choice.
