MikroTik NET REPEATER/GPER

The GPeR unit allows to extend Ethernet cable by additional hop (< 100 — 150 m to regular network devices, and up to 210 m to another GPeR unit) up to 1,500 m.
Handy for highrise buildings, multi-apartment buildings, with many floors and sections, where very long Ethernet cables might be a problem.
Maximium allowed length of CAT6 Ethernet cable between GPeR and power source/router is up to 100 m (depending on cable quality, high quality — up to 150 m).
Maximium allowed distance of CAT6 Ethernet cable between two GPeR devices is up to 210 m (depending on cable quality).
In case if the destination device does not support PoE-in powering, the PoE Passthrough can be disabled by manually removing all jumpers.
