If you deploy VDSL2 to support modern speeds, you need to have a maximum
distance of roughly 500m between all homes and the DSLAM. This costs a
lot of money because installing a DSLAM outside is costly. Concrete
base, bringing the fibre AND POWER to it, and then bring all the local
copper there.
The old copper telephopne plant was often not architected to bring all
the copper in a neighbourhood togthere before going to the central
office, so it becomes hard to have at junction boxes that meet your
distance standards.
In my case, the distance standard is 1km and the DSLAM that serves me is
within eyesight of the central office that has a more modern DSLAM in it.
In Australia, the curent govt, while in opposition, was lobbied by
Tesltra to push for the govet renting Tesltra's copper. So as soon as
Turnbull got into power, he directed NBN to stop deppoying fibre and
deploy FTTN (DSLAMs near homes) and promised great speeds. Now, not
only have FTTN costs gone up, but they have also loosened the standards
otherwise the costs would have been way too high, and the latest is that
it will end up cositing the same as FTTH, but give unreliable and
variable speeds.
Each country is different on how it deployed its copper originally and
how it can be converted to FTTN service or whether FTTH ends up being
better.
Also, FTTH ends up costing much less is yearly maintenance and
performance does not degrade due to rain and squirrels as copper does.
