PON in urban areas absolutely makes
sense. Maybe less in a high rise area, where each
building can have a small building wide network of
its own. But it in areas with single family homes
PON is king.
Our POPs can have up to 10 000 customers
each. All on a single 96 fiber strand cable leading
into the POP building. We have extra ducts, but
nothing that would allow us to change that to a
point to point network. That would require 100x that
96 fiber cable.
With extra ducts it would be possible to
rebuild from PON to point to point. But it would
require massive investments. Basically you would
have to invest all that we saved by building PON.
For starters, you would have to have many more POPs.
And yes, there are splitters in the hand
holes. This is not what stops you from rebuilding
from PON. It is the fact that we never paid for
extra fiber. The backbone in a sub area is typically
build with a 24 fiber strand cable. Because fibers
are not free and are actually quite expensive as the
number of fibers grow and the distances get longer.
We can do a few point to point connections, for
example if we need to deliver a commercial service
or for our own needs (to connect POPs etc).
We are not big on commercial services.
But if we were, I would use WDM splitters for that.
Or the long awaited 10G PON if that ever arrives and
turns out at a price point that works.
