OM4 fiber is rated at 10GB up to 500m or ~1800ft, and the amount of current that 12AWG copper could carry at that distance with acceptable voltage drop is pretty low, so you'd probably still need to be stepping the voltage up and down on each end. I looked into this recently daydreaming about building a small office in the woods.
