GPEN (Gigabit Passive Ethernet Network) Concept

Cut costs, not speed – forget about the expensive GPON!

This is the cheapest way for any ISP to deliver high-speed internet to individual apartments.

MikroTik GPEN concept can replace any existing or future GPON solution. It provides all the benefits of GPON, but utilizes well-proven, simple and inexpensive Ethernet solutions.

GPEN doesn’t require expensive GPON OLT equipment in your server rooms, just a regular switch port!

Similar to GPON, GPEN solution will require clients to provide power, but instead of powering GPON’s ONT device, power will be used for extending the Ethernet cable (with our GPeR devices) and powering the netPower device. That is the GPEN analogue of GPON Passive optical splitters – netPower provides additional functionality and possibilities.

And the best part of this technology – it give you all the flexibility for a fraction of the price. You can connect netPower to your server room by Ethernet, Active optical line or use it to power one end of point- to point backbone wireless link. GPEN – the evolution of GPON done right!


The GPEN11 is a power injector that can power your uplink devices via PoE. It is part of the GPEN (Gigabit Passive Ethernet Network) concept, which aims to replace GPON installations with lower cost and more easy to deploy Ethernet alternative.

It also has a designated space for an ISP sticker on the front. Sticker size: 66 x 25 mm (2,5 x 1 Inches).


The GPEN21 is a smart power injector that serves as an advanced software controlled repeater. Not only can it power your uplink devices via PoE, it can also provide a range of useful software features:

It also has a designated space for an ISP sticker on the front. Sticker size: 66 x 25 mm (2,5 x 1 Inches).

• Interface management and monitoring • GPEN link fault detection
• VLAN support
• SNMP reporting

• Basic Traffic Shaping

GPEN21 has an Ethernet and SFP port for fiber connectivity. Customers can choose to use GPEN21 to power optical module for uplink to provider, or to provide PoE to power Ethernet uplink to provider (that uses our GPER and/or NetPower products) The GPEN unit can be securely attached to a wall or the communications cabinet. The Ethernet cable can be routed either directly through its bottom cable opening or into the wall, as preferred.

GPeR IP67 Case

We bring you a sturdy and affordable outdoor enclosure for GPeR units. It can be easily mounted on walls and poles. Despite the name, meticulous testing revealed that in real life the enclosure has an IP68 rating with protection from immersion in water, as well as protection from dust. Get an outdoor enclosure for the GPeR to safely extend Ethernet network in mines, caves, maintenance shafts or outdoors.

netPower 15FR

With netPower 15FR switch you can forget about expensive GPON base stations and optical splitters. This switch is a part of our GPEN concept – aimed to bring the speed and versatility of fiber networking while using the advantages of Ethernet. It is a cheap and easy to deploy way for any ISP to deliver internet to individual apartments.

  • You don’t have to worry about power options in the attic or the utility room – netPower 15FR has 15 reverse PoE-in ports. Depending on your setup, netPower can draw the necessary power even from a single client! Another Ethernet port has PoE-out – you can use it to power an aggregate link such as our Wireless Wire Dish or a security camera, for example.
  • There are two SFP ports for fiber connectivity. The outdoor enclosure allows you to install this switch in all kinds of environments – from damp attics to elevator shafts.

    netPower 15FR has a non-blocking throughput of 3.6 Gbps, switching capacity of 7.2 Gbps and forwarding rate of 5.4 Mpps.
