[AusNOG] ITWire - A spanner in the NBN works? Alcatel-Lucent gets 100Mbps over 1km of copper

[Curtis Bayne]

There is no argument that fibre is a superior technology, but at what cost? Consumers make no definition between the way in which a service is delivered - they care only about the performance of the product. The proliferation of 3G services is a testament to this.

Process vs Product. Product sells, process does not.

I still consider fibre a far better alternative in terms of upgrades for 
our future development rather than the age-old degrading copper 
infrastructure.
