<div>Is this NBN policy to do max 32:1 splits to keep
contention to certain level? because thats not a technical
limitation or ALU's limitation for sure.</div>

The fibre distribution hubs they are installing have 32:1 splitters
in them. Generally they aren't using every port on the splitters and
I believe the design was to use a max of 24 ports per splitter
though don't quote me on that.<br>
