your fiber is lit

This line from an Econmost article sums up the future of the wireline telecommunications

"After a century of communication over copper, the future will belong to those who can best replace it .."

BTW, if you subscribe to the Verizon FIOS service in New Jersey, they will not only install the fiber to  your home and light it up, but they will make sure that they have removed the copper lines coming into your home so that you have not way of going back to the old ways !
