For the high speed business systems, the typical configuration is to have a fibre back bone between the major nodes, and CAT 6 copper cable to computers etc.
The fibres are capable of speeds in excess of 10 000 megabits / second, while the cat6 can only do 1000Mb/S. However, whilst most Internet connections fall below 10Mb/s this is generally not a problem.
The major network problems are not the hold hold connections, but the back bones. While existing phone lines to homes are not cat5 or Cat6 cable, they are still mostly capable of speeds in the 10-20Mb/s.
An earlier proposal for the NBN was to upgrade the backbone to street corners, and continue to use the existing phone lines. This would have given 90% of Australian customers the same service that the New super delicious network proposed by Stephen Conroy has proposed.
The cost difference is massive. The proposed backbone upgrade was estimated to cost $5bn, whereas the Conroy version is to cost $43bn.
Having fibre to my home, would also mean that I would need an expensive fibre to copper converter, as PCs don't take Fibre. PCs are configured to take up to 1000Mb/s so the 10Gb/s capability of the fibre is wasted. I have a 30GB monthly plan. At 10Gb/s I could theoretically use up my entire monthly allowance in 24 seconds. However, the reality of connections to the outside world would require that speeds be truncated to levels not much higher that 10Mb/s.
The difference between the cost of the two scenarios is about $7500 per house hold, which whether we like it or not, we will have to pay for.
The agreement with Telstra and the NBN is that when the fibres are pulled in, the copper is removed, so is the choice.
