What Is MikroTik MT48-570080-11DG?

The MT48-570080-11DG is a dedicated power source for extended Ethernet distribution systems.

A typical installation may look like:

AC mains → MT48-570080-11DG → GPEN injector → Ethernet cable → GPeR → Ethernet cable → GPeR → netPower/device

The adapter itself does not repeat Ethernet data. Instead, its purpose is to provide the electrical power that GPEN devices and compatible PoE equipment use over the Ethernet cabling.

This distinction is important because the MT48-570080-11DG has no networking interface, switching function or RouterOS configuration.

Key Features of MikroTik MT48-570080-11DG

1. 57V DC Output

The adapter delivers 57V DC, which is at the upper end of the voltage range supported by several MikroTik PoE and GPEN products. (mikrotik.com)

This higher voltage is useful when power must travel over long Ethernet cable runs because voltage drop becomes more significant as cable distance increases.

2. 0.8A Current Capacity

The power supply delivers up to 0.8A.

Its nominal output capacity is:

57V × 0.8A = 45.6W

MikroTik's official GPEN documentation identifies the MT48-570080-11DG as a 45.6W adapter.

3. Designed for Long Ethernet Runs

This is not simply a replacement router adapter.

MikroTik specifically designed the MT48-570080-11DG so installers can use:

• Long Ethernet cable runs

4. Part of MikroTik GPEN

GPEN stands for Gigabit Passive Ethernet Network.

MikroTik developed GPEN as an Ethernet-based distribution architecture aimed at giving ISPs a simpler alternative to some GPON-style deployments. Instead of requiring an optical network terminal at every customer site, GPEN can use Ethernet, GPeR repeaters, netPower switches and customer-side power injection.

The MT48-570080-11DG plays an important role because the power provided at the customer's end can travel along Ethernet cabling to power intermediate repeaters and downstream equipment.

5. Works with MikroTik GPeR

The MikroTik GPeR is a Gigabit Passive Ethernet Repeater designed to extend Ethernet beyond a normal cable segment.

MikroTik states that one GPeR can provide an additional less than approximately 100–150 metres to a conventional network device, while the distance between two GPeR units can reach approximately 210 metres, depending on cable quality. Multiple GPeR units can be used for much longer links. (mikrotik.com)

The GPeR accepts 24–57V PoE input, which makes the MT48-570080-11DG's 57V output particularly well suited to extended GPeR deployments. (mikrotik.com)

6. Better Long-Distance Power Budget

One of the most important advantages of MT48-570080-11DG is visible in MikroTik's GPEN design examples.

MikroTik compares 24V, 48V and 57V sources over different cable distances. In the published examples, the 57V 0.8A supply retains more useful PoE-out power at longer distances than the 48V 0.95A option.

GPEN Distance Examples with MT48-570080-11DG

Approx. Cable DistanceNumber of GPeR UnitsPowers netPowerApprox. Remaining PoE-Out Power100 m0Yes19.5–20.5W175 m1Yes17.5–18.5W310 m2Yes10–14W500 m3Yes3.5–7W

These are MikroTik GPEN planning examples rather than guaranteed field results. Actual power availability depends on cable resistance, cable quality, connector losses, equipment consumption and installation conditions.

7. Can Support a 500-Metre Example Link

MikroTik's GPEN guide shows a 500-metre example using three GPeR units with a 57V supply. In that scenario, netPower remains powered and approximately 3.5–7W may still be available for downstream PoE-out.

This is one area where the 57V adapter outperforms the 48V 0.95A MT48 supply in MikroTik's example calculations.

The 48V version can still power netPower at the 500-metre example distance, but MikroTik lists no remaining PoE-out budget there.

8. Suitable for Multi-Building Networks

The MT48-570080-11DG can be useful where network cabling must travel through:

• Apartment blocks

• Hotels

• Schools

• Universities

• Warehouses

• Office compounds

• Industrial sites

• High-rise buildings

• CCTV networks

• WISP distribution networks

• Rural internet installations

The GPeR itself is specifically promoted by MikroTik for high-rise and multi-apartment environments where conventional Ethernet cable distances can become a challenge. (mikrotik.com)

9. Useful for CCTV and Access-Point Networks

Extended Ethernet links are often required where IP cameras, wireless access points or remote switches sit several hundred metres from the main network room.

With properly designed GPEN infrastructure, the MT48-570080-11DG can supply power through multiple GPeR hops while leaving some power available at the destination.

The available PoE budget must always be calculated before selecting the final camera, access point or radio.

10. No RouterOS or Configuration Required

It has:

• No RouterOS

• No SwOS

• No Ethernet port

• No SFP port

• No CPU

• No IP address

• No web interface

• No firmware

• No WinBox configuration

No software setup is needed.

Installing MikroTik MT48-570080-11DG

Before installing the adapter, determine the total Ethernet distance, number of GPeR repeaters and power requirement at the far end. MikroTik's GPEN examples demonstrate that the available downstream PoE budget decreases as cable distance and the number of GPeR units increase.

Use good-quality solid-copper Ethernet cable and properly terminated connectors. MikroTik specifies up to around 100 metres between the power source/router and GPeR under normal conditions, potentially around 150 metres with high-quality cable, and up to approximately 210 metres between GPeR units depending on cable quality.

For outdoor, rooftop or inter-building installations, also include suitable surge protection, grounding and weatherproofing. The 57V adapter improves the available long-distance power budget, but it cannot compensate for poor cabling, damaged connectors or an improperly engineered PoE system.

The MikroTik MT48-570080-11DG is a specialized 57V 0.8A, 45.6W power supply designed for long Ethernet and GPEN installations. It works particularly well with MikroTik products such as GPeR, GPEN11, GPEN21 and netPower, allowing installers to distribute Ethernet and power across significantly longer copper cable runs than a normal single Ethernet segment.

Its biggest advantage over the 48V 0.95A MT48 adapter is its higher operating voltage. MikroTik's own GPEN planning examples show the 57V supply maintaining approximately 10–14W at 310 metres and 3.5–7W even in a 500-metre, three-GPeR example, giving installers more flexibility when downstream equipment also requires PoE power.
