 [A couple of good articles on next generation FTTH architectures which
allows for easy structural separation and competition, and based on
experience in Sweden, enables greater traffic growth.  It is also
interesting to note that the wireless cellphone industry  in the USA has
largely moved to similar structural separation architecture, where the
companies that own and operate the towers are independent of the network
operators. Because of intense cellphone competition in the US, most have
come to realize that is a lot cheaper to have someone else own and operate
the towers which can be shared by many different network operators. There
are many thriving companies that specialize in this business - so much so
that they have their own index in the stock market.  Companies like American
Tower Corp, SBA Communications etc dominate this burgeoning field. We are
starting to see such specialization in the FTTh market in jurisdictions
where cities own and operate telecom conduit or dark fiber like Montreal,
Stockholm, Amsterdam, etc  --BSA]

FTTH is a hot topic already and it is only a matter of time before investors
start realizing the true potential by launching special products or
investment funds. ...The Swedish Ventura Team recently reported on usage,
which provided some reassurance to anybody displaying scepticism over what
to do with all that bandwidth. 

Their main findings:

    * Nielsen's Law (available speed increases at a 50% CAGR) generally
holds. The Ventura Team expects it to hold for at least another decade. This
means that 100 Mb/s will be available in France in 2008, in Poland in 2012
and in the UK in 2015.
    * The mass market lags the high-end user by 2-3 years.
    * FTTH customers generate >3x more traffic. Surprisingly, the
inbound/outbound traffic ratio seems to be similar to the one for ADSL
networks (notwithstanding an expected P2P concentration on FTTH networks).

Pendulum swings away from controversial fibre technology

Proponents of GPON fibre-to-the-home (FTTH) technology were dealt a number
of blows at last month's FTTH Council Europe conference in Paris.
The European Commission, independent experts and even some incumbents used
the FTTH-equipment manufacturers'annual event to voice concerns - and
criticism- about the controversial approach to building next-generation
access networks.

"Once you have a PON network, really how to unbundle this network is still
very unclear,"

Next Generation FFTH architectures - home run fiber

http://www.internetevolution.com/author.asp?section_id=506&doc_id=148966&

European telecom regulators have expressed an intense interest in the future
architecture of FTTH (fiber to the home) networks. They're concerned that
choosing the wrong architecture will make future unbundling difficult and
make it impossible to create a competitive broadband market. The most
flexible alternative is a "home-run" fiber architecture, which will allow
for true unbundling and create a level playing field in the market.

The telcos and their equipment suppliers are almost universally pushing for
the emerging GPON technology, while many municipal networks and innovative
startups, such as PacketFront, are pushing for Ethernet point-to-point.  A
pox on both their houses, I say.

The telcos love GPON (Gigabit Passive Optical Network) because it keeps them
in control of the network. Although there is some talk of "virtual"
separation with wavelengths and so forth, it still leaves one carrier in
charge of the network.  The other challenge with GPON is that, once it is
deployed, customers are locked into this type of architecture for the next
20 years, with certain assumptions on traffic flows and ratios based on
today's understanding of networks.

If there is one thing we have learned over the past decade, future network
demand will likely exceed our most optimistic projections. Ethernet
point-to-point is a bit more future-proof, but its main drawback is the
deployment of active equipment in the field. This equipment will need power
and ongoing servicing.

But there is good news.  Regulators don't have to choose between these two
unappealing approaches for FTTH. They could decide on"home-run" fiber
architecture
