Fiber optic wire has a very high voltage wire to power the amplifiers. (Interestingly, it's only one. The ocean water provides the return path.)

- jimktrains2 12y agoI guess I figured copper wire would also required amplification. Interesting on the return path. Where does the source connect i.e. one side of the "battery" goes to the amplifier (which returns to the sea, not the battery) and the other side of the battery goes to where? the sea?
