Masataka,

Numbers?  Examples?  This is simply incorrect in many places.  The only
reasons to run PON are financial, since Ethernet out performs it, are you
saying that all greenfield PON installs are cheaper done as Ethernet
without exception?

The fiber plant would presumably be paid for with 30-year bonds, same as
any other municipal infrastructure (eg. water and sewer lines--the real
"pipes"), for which interest rates are currently running around the rate
of inflation.  There is no need to pay them off quickly.

In addition, as PON is even less efficient initially when
subscriber density is low and there are few subscribers to
share a field splitter (unless extremely lengthy drop cables
are used, which costs a lot), PON is slower to pay them off.
