This is not possible in a GPON system. The OLT has to be carrier neutral
so that different carriers can connect to it. It is the last point of
aggregation before reaching homes.

Otherwise, you would need to run multiple strands to each splitter box
and inside run as many splitters as there are ISPs so that one home an
be connect to the splitter used by ISP-1 while the next home's strand is
connected to another splitter associated with ISP-2. This gets complicated.


Why can't the splitters be in the MMR? (I'm genuinely asking... I confess
to a certain level of GPON ignorance).


Much simpler for the municipality to run L2 to a single point of
aggregation where different ISPs can connect.  In the case of Australia,
the aggregation points combine a few towns in rural areas. (so multiple
OLTs).


Yes, but this approach locks us into GPON only which I do not advocate.
GPON is just the current fad. It's not necessarily the best long term
solution.
