Masataka,

Using the UK as a model for US and Canadian deployments is a fallacy.  The
population density there is 673 per square mile, much closer to Japan's
(873 per sq mile) than either the US (89 per sq mile) or Canada (10 per sq
mile).  The UK also has a legal monopoly for telephone infrastructure and
very different regulatory system.  Using the UK for anything in this
discussion is simply wrong.

You may be a brilliant conversationalist in Japanese, but you're not making
a convincing argument in English and simply railing that your position is
correct without regard to countering information isn't going to convince
anyone.  Keep on this track and you're just going to be ignored by most
people on the list.

The examples are in rural area and I already stated population

No, the only reason to insist on PON is to make L1 unbundling
not feasible.

I don't know what conspiracy theory you're ascribing to here, but this is
incorrect.

PON being more expensive than SS, that is the only explanation.

No, SS is cheaper than PON without exception.

Prove it.

See above or below.

If the initial density of subscribers is high, SS is fine.

If it is not, initially, most electric equipment, OE port,
fibers, splitters and a large closures containing the splitters
of PON can not be shared by two or more subscribers, which means
PON incurs much more material and labor cost for each initial
subscriber than SS.
