Several years ago, ATT spent lord only knows how much money
to dig up all of the yards in my neighborhood and run fiber optic cable.
They connected the houses to the fiber optic line with two copper wires.
I never could understand the point of it all.
Copper performs well for short runs and is easier to connect than fibre. Reducing the length of the copper wire can improve performance dramatically; a 30-foot run can support gigabit speeds.
