So cool that there's a ton of articles on the
Internet about it right now. So why talk about
it again in the <em>4cast</em>? Because there's
some cool technical stuff going on in the
background that few of the news articles have
mentioned. Google is essentially putting
dedicated fiber strands in every customer's
house, which is different from the current
Gigabit Passive Optical Network (<a
href="http://www.alcatel-lucent.com/technology/gpon/">GPON</a>)
technology used by many telcos to provide
shared, on-demand, high-speed Internet service
to homes.

O'Connell: FTTH not just a Verizon thing</a>
(interview with Cable360) "Various FTTH [fiber
to the home] technology solutions present
alternatives in this regard on such issues as
building out shared vs. dedicated plant,
offering gigabit capacity today vs. something
less now until gigabit service levels are
demanded to support common applications and so
forth. Providers also have to weigh the pros
and cons of maintaining active electronics in
the field vs. operating a passive network, <em>vis
a vis</em> the services or bandwidth
capabilities those respective solutions may
allow them to deliver, and the operational
considerations of supporting those respective
designs."</li>

Fiber - Less Filling (cost) Tastes Great
(more bandwidth)?</a> (Technology Directions
by Wesley Kaplow) "Any service, virtually no
matter the technology, has aggregation points.
With GPON technology the concentration point
is at the Optical Line Termination equipment
(OLT). [...] Also at the OLT is the amount of
uplink bandwidth from the OLT to the Internet.
In general there are one to four 10Gbps uplink
connections. So, in the best case there are
40Gbps to spread over the hundreds of
customers connected to the OLT."</li>

routing fiber connection into Kansas City, KS
and Kansas City, MO through several equipment
aggregator huts, aka 'Google Fiber Huts.' From
the Google Fiber Huts, the fiber cables will
travel along utility poles into neighborhoods
and homes. The benefit of this model is
simple: every home that has Google Fiber
service will have their very own fiber-optic
cable that directly connects all the way back

like Google on a bigger scale, the statewide
OPLIN network provides dedicated, symmetric
circuits capable of either Fast Ethernet
(100Mbps) or Gigabit Ethernet to most libraries.
To control costs, however, we also carefully
watch the demand from the library and ask the
telco to restrict each connection - and their
bill - to the amount of bandwidth the library
actually needs.
