Recent reports plus or minus. The amount of fibre connections should be just over 1 million, not just "homes passed" but actual connections available. Hard to put an exact figure from all networks as they use different metrics of reporting. Telkom had around 5-6 million lines almost all of them adsl capable. Could be less now with theft and decommissioning.Yes. But unfortunately Telkom doesn't appear to be growing their base of a phone in every house so they can only roll out DSL connections to those houses that have.
Where did you get these figures?
The point is there's a lot more people with adsl availability. Most however choose wireless. Fibre penetration would need to increase by at least 500% before it will be on par with adsl. Not something that will happen in the next few years.
