Mikrotik GPeR Gigabit Passive Ethernet Repeater - Long Reach Extension

In this review the Mikrotik GPeR is evaluated as a focused tool for extending Ethernet runs in buildings where long cable runs are unavoidable. The bottom line: installers and DIY networkers who need to stretch a CAT6 run well beyond the usual 100 m limit will appreciate the GPeR because it provides additional hops and PoE passthrough to push Ethernet up to 1,500 m in total when chained correctly. For projects in highrise or multi-apartment buildings where running new fiber is impractical, the GPeR offers a simple, passive way to reach distant devices.

Key Features

• Extend Ethernet Reach: Adds additional hops so CAT6 cable runs can be extended incrementally to reach very distant endpoints without complete rewiring.
• Long Inter-device Distance: Supports up to 210 m between two GPeR units, allowing fewer repeaters across very long vertical or horizontal runs.
• Standard Cable Limits: Allows up to 100 m (and under high-quality cable up to 150 m) between the GPeR and the power source or router, keeping compatibility with typical Ethernet practices.
• PoE Passthrough: For destinations that accept PoE-in, the unit can pass power through, simplifying remote device powering without separate power runs.
• Manual PoE Disable: If the destination device does not support PoE-in, the passthrough can be disabled by removing jumpers, preventing accidental powering.

Who It's For

The GPeR is best for installers, building IT staff, and advanced DIYers working in highrise or multi-apartment environments where cable distances routinely exceed 100 m and running new fiber or conduit would be costly. It is well suited to situations where multiple hops are acceptable and where compatibility with CAT6 cabling is preferred.

It is less appropriate for casual home users who have short runs under 100 m or for deployments that require active managed switching features; the GPeR is a passive repeater focused on reach, not switching or advanced network management.

Pros & Cons

Pros

• Extend cable runs in stages to reach remote endpoints without new fiber installations.
• Supports PoE passthrough to power remote PoE devices when needed.
• Clear cable-length guidance (100 m typical, up to 150 m with high-quality CAT6) helps plan installs.
• Allows longer links between repeaters (up to 210 m) for flexible placement.

Cons

• Passive design means it is not a managed device and depends on cable quality and correct jumper configuration.
• Performance and distances depend on CAT6 cable quality, so results vary by installation conditions.

Our Verdict

The Mikrotik GPeR is a pragmatic solution for long-reach Ethernet needs in large buildings: simple to deploy, compatible with CAT6 cabling, and useful where phased extensions are required. Installers who need to push connectivity across floors or long corridors will find it good value, provided they account for cable quality and the passive nature of the device.

Frequently Asked Questions

Can I chain multiple GPeR units?
Yes. The device is designed to be chained to extend Ethernet up to about 1,500 m total, with up to 210 m between GPeR units depending on cable quality.

Do I need special cables or power supplies?
No special power supply is required when using PoE-in from a compatible source; use high-quality CAT6 if you want the maximum distances noted.

What if my endpoint does not support PoE?
If the destination device does not accept PoE-in, the GPeR PoE passthrough can be disabled manually by removing the jumpers to avoid powering the endpoint.
