I have just been reading an article on the capacity of the data cables going from Sydney through to Guam, and then on to the US. Currently it stands at 4Gb/s but with the new cable from Pipe Networks that should increase over time to 6Gb/s.
Trouble is that doesn’t stand up with a 100Mb/s NBN. When you look at the figures: –
The totally capacity coming into Australia when this is up to capacity will be 6Tb/s. The NBN will provide data connections at 100Mb/s or 0.1Gb/s. That means that just 60,000 connections at a full 100Mb/s, or assuming that maybe 20% of households are on the net at the same time connecting to the US (20% of 8.5M households is 1.7M connections) gives just 3.5Mb/s per connection.
Okay I know that there will be local caching, but this is going to need to be huge in order for us to see more than a connection at roughly the same speed as ADSL.
