10 Tbps capacity planned

In many cases, these are private funded cables in an ever more competitive world. So, given standard supply & demand in economics, an over supply will lead to a sharp reduction in prices. Do their models take into account a sharp upturn in demand as a result of the reduction in prices?
 
Good news. But a bit misleading to just total all the cables up to 10TB.

It's the same as saying "Africa has 500 000 km's of roads". It doesn't mean you won't get traffic jams in your city.

More than a bit misleading.

Current WORLWIDE capacity in undersea cables = 7.1 Tbps
of which 5.7 Tbps has been purchased for expansion.
Of that purchased capacity current utilisation peaks at 2.1 Tbps.
Of that 2.1 Tbps used capacity 72% is internet, 1% is switched voice and 27% private networks.

So if we make some calculations, if africa gets 10 Tbps by whatever date as I see no dates to any of this speculation.

Africa will have to invest 29% more money than the current TOTAL investment into undersea cables (10 Tbps - 7.1 Tbps is 29% difference).

The rest of the world CURRENTLY use 2.1 Tbps in total. Africa wants to host how much of the worlds data to utilise 10 Tbps. Thats a roughly 700% increase in the current usage.

I think here credibility starts to collapse. I dont think I need to go further do I.

Interesting. Lucky none of us ever could need more than 64kb of Ram.
 
maybe if we are luck telscum will give us fiber into our homes with all of those extra capacity i cant see why not
 
The total design capacity of all planned cables is 10 Tbps (up from the baseline of less than 400 Gbps currently).

"When these cables have been completed there will be a vast amount of excess capacity," adds Chanakira. BMI-TechKnowledge expects demand from Africa will increase to just 300 Gbps by 2015, and a maximum of 2,000 Gbps (2.0 Tbps) by 2019.

So there is enough capacity until 2015! Or where do I go wrong?
 
The problem currently is high priced international capacity and that's (supposedly) going to change with all these new cables.

The problem then will be that we have this glut of international connectivity, but still 156k, 192k and 384k terrestrial lines. It's more expensive to backhaul traffic via a 100Mb ATM cable to JHB from CT or Durban than it is to get a 1Gb link from Europe to the US. That's where the main problem lies.
 
This is all talk and will not affect SA internet at all.
