Electrical and fibre optic...
Why is it that a fibre optic cable must boosted less frequently than an electrical signal in a copper wire, I understand that there will be resistance in the wire and thus the voltage will drop the further you go, but surely there will still be the changes in voltage, and it is this which is important in the signal. Why do we not just wait till our destination before we amplify the electrical signal?
Thanks.
