Cheaper, greener. Perhaps cheaper is the more important here.
Fibre is much cheaper and less energy intensive to make and far less
energy to run than copper. So far it has been the terminations and
optical transceivers that are more expensive. I imagine this will
change eventually. For instance if nearly every household in
Australia has one - it might help bring the price down.
