They're basically bridges rather than repeaters (a repeated is a level
1 signal relay, whereas bridges and switches are level 2 packet devices
that effectively create a separate ethernet with a common level3+
address structure.)

And I'll bet POE has more trouble sending POWER over 1km than a
typical ethernet interface has sending signal over that distance!
