Adsl was only performing sub par due to poor backhaul when you have a crappy ISP with a crap network. There will be more healthy competition as fibre spreads and if you have an "oversubscribed" network you just move to another ISP. Face it adsl had too many problems, the biggest being the copper being stolen and it taking telkom ages to replace. Fibre is less susceptible and have better security in place to detect tampering (I have spoken to somephone that lay fibre myself)Because the two perform the same apart from the attenuation factor as I pointed out. Where adsl was performing sub par it was generally due to poor backhaul. Fibre isn't going to miraculously solve that on an oversubscribed network. Adsl could still have had a long lifespan if it was handled correctly by Telkom and allowing open access.
Like I said before, show me 'those people' and I will almost guarantee you it is a badly run network or related to other non-contention issues.There are a few people complaining of low speeds on fibre. So far it's been put down to badly run networks but I don't think that's the case.
This argument make me think of the people in the xiaomi thread complaining the mi box has bad wifi but in the meantime they must just change the channel on their router to fix the issue.
I would say it is 99% immune to those issues. I do support for a lot of small businesses and the area I serve is not immune to lightning strikes at all. Most of my business was replacing UPSs, PSUs and modems - a huge issue with copper lines. And had a few customers in areas that was badly maintained by telkom where the terminating box for the adsl was not properly sealed and the moss was growing on the terminals causing the lines to fail.Sure but fibre isn't immune to most of those. Adsl was only limited to the dslams installed. Ironically Telkom artificially limited it by insisting on a pots line as well. Weather and other interference? Never heard of those having a big impact except with direct strikes which are a rarity.
So yeah plenty of weather related issues
