I guess the question is can she actually get any content to download > 1Gbps? 
They cite this as worlds fastest home broadband but didnt Peter install an OC-76
8 to his basement a few years ago when he was testing some stuff for Sprint?
Steve
His bathroom, IIRC. And I heard a rumor about his g/f's flat.
Isn't Peter on this list?
This story has spread a lot, I'm actually quite surprised, but Peter is
good at PR.
The point he tried to make was that fiber can carry high speed
communications as opposed to other people who seem to think radio is the
future. The equipment used (the CRS-1 OC768 DWDMPOS linecard) has been
shipping for over a year so that's not new. Sprint did test with beta
versions of this LC in 2004:
<http://www.lightreading.com/document.asp?doc_id=53816>
What I like about it is that it uses single 50GHz wave that can traverse
existing DWDM systems designed for 10G waves but that can now carry 40G.
So basically there is little new with this test, but the amount of
publicity it has received I interpret that the technology is fairly
unknown even to professionals in the business, so it might have been a
good thing after all, as it made more people aware of what's possible.
I sat at the Stockholm end when he brought up the wave and it was
surprisingly easy to get it all to work, if this was real production
traffic I would have liked to do more verification and testing, but it
shows that some IP people can bring up new waves in a DWDM system using
routers as end nodes, one doesn't need a huge transmission staff to do it,
neither does one have to have SR-DWDM transponders.
I believe that was a GSR. He has his picture albums linked from
<http://www.stupi.se> you might be able to find something there. I know
I've seen pictures from the flat.
For those who haven't followed the links, the story is that Peter's
mother, a first-time computer user, now has a 40 Gb/s Internet connection
to her house. It is described as the world's fastest residential
Internet connection. It was done as a demonstration project by Peter and
the local city council "to persuade Internet operators to invest in faster
connections." It goes on to say that "Peter Lothberg wanted to show how
you can build a low price, high capacity line over long distances."
So, I'm curious here. The only thing specific the article says about the
price is that Cisco contributed the equipment, but there may be economies
of scale that could make one end of this more affordable in larger
volumes. Data transmission at that sort of speed is certainly a topic
Peter knows a lot more about than I do.
The thing I found more curious was the article's emphasis on the distances
data can be transmitted over fiber:
"The secret behind Sigbritt's ultra-fast connection is a new modulation
technique which allows data to be transferred directly between two routers
up to 2,000 kilometers apart, with no intermediary transponders."
Does this make residential connectivity (or at least, residential
connectivity on a large scale) any easier? Wouldn't residential fiber be
expected to radiate out from neighborhood break-out boxes, or at the
longest from a central office in the middle of town, rather than having
some central point where enough individual strands of fiber converged to
serve everybody in a 2,000 kilometer radius?
So, Peter, are you reading this? I'm curious what the real story on the
economics here is. How affordable is affordable? What should we be
learning from this that would let those of us backwards people with DSL
connections cheaply move into the modern world?

It's a demonstration of backbone technology, not really access technology.
It just makes its appeal better in the media if you put it in your mothers
house.

It's not even that. We all know that 40G technology exists today, this
article doesn't prove anything. How about they fling their magic wand
some more and show us where 40G to the residential marketplace is a
viable business model. By todays technology costs to make that happen
and what the average residential consumer pays, your ROI is about 20
years. 
-Robert
I have to disagree, considering the amount of people I've had to convice
that this really is a single 50GHz wave using 40G per second over DWDM
system designed for 10G and that it was router
"LC - optical amplification - LC"
with no transponders of any kind. I've sent the Cisco product link on IRC
4-5 times in channels populated by otherwise quite knowledgable people.
Some didn't even know that LC existed even though it's been shipping for
over a year.
People have been under the impression that this was 4 10G waves, each
using 50GHz.

On the contrary, I think that it proves again that Peter has a deep
understanding of publicity.

which is, i believe, the point of the publicity stunt. unfortunately,
it does not help with us needing 100GE and more in the pop where this
stuff aggregates. and, for those who remember when peter did the
similar stunt to make the POS point, let's hope cisco does not try to
sell us a merlin-like hack to deal with it until the ieee gets off its butt.

Well yes, the technology is quite cool, I'm not debating that. The fact
that it works at his mothers house (residential) doesn't really have any
significance. I don't think you have anyone out there debating against
caping out the upper limits of bandwidth on what we can get over a
single strand of glass.
I look at this article and say "so what". Now you've gotten the packets
to the house. Now what? Wait 10, 15 or 20 years while companies try to
find ways to get content do you? 1500 HD channels, thats a lot of TV
sets. You can have all the bandwidth you want, but but until there an
actual use for 40Gbps at the home all you're going to have is the worlds
fastest BitTorrent or on net porn PPV network.
How practical is it really also that you need CRS-1 at the residence for
this. I agree with Sean. Since for most people the line card alone
costs more than the house.
-Robert
I hope everybody tells their vendors that 100GE is of high importance for
them. The IEEE HSSG seem to be bogged down by 40GE vs 100GE right now with
some voicing very strongly that 40GE should be included together with
100GE goal, mostly from the fibre channel and server folks.
If you want 100GE by 2009-2010, please read up at
<http://www.ieee802.org/3/hssg/public/index.html> and voice your opinion
either on the email list or via your vendors.

Uncompressed HD TV (typically 1.54 Gbps / channel) comes to mind, for
which there are applications, albeit typically not residential so far.

40Gb/s per slot routers are not that rare at this point. So the notion
that you need a crs-1 in order to capitalize on 40G is I think
demonstrably false.
The amount of link aggregation being done at 10Gb/s would tend to
indicate that need for > 40Gb/s links is becoming acute enough to make
it a commercially worthwhile problem to solve if not cheap for the early
adopters.
As consumers we would all benefit from standardization of 40 and 100Gb/s
ethernet phy.
As I said, "at the residence". I could care less if it's a CRS-1 or
Acme router. My point is, you're not going to find any 40GB capable CPE
now or in the foreseeable future that's going to be affordable for the
residence.
I know the intention of the article was to demonstrate the technological
advantage of fiber optic networking vs. other technologies, but to mask
the article around something that seems to indicate that "40GB to the
home" is somehow the current benchmark is incredibly unrealistic.

i would agree if we had not once said that about a few meg per sec.

What would be the best way to phrase it? 40TTH? GTTH (gigabit to
the home)?
If you can use the Indian name for 10 million in there somewhere, you
can brag about "quad-crore" speeds ...

I can see that *everybody* is missing the point on Peter's exercise.
Clearly this is to show to the telcos of the world that you can upgrade to a
native IP infrastructure and absorb the existing transport into the router
with a minimal effort. There was a post here from someone that was there
that explained how simple it was. This is HUGE! This has the potential to
completely disrupt telco transport dinosaur groups *and* reshape the
future. Taking it to his mom's house is just a poke in the telco eye, he is
making fun of them. This then begs the question why can they do it between
their facilities? If one guy can do it to a *house* it must not be that
hard. However, telcos with transport groups of 1000s can't pull this off,
this little project states volumes.

If we continue along orders of magnitude, sure it's foreseeable.
* 30 years ago, 300 baud was the bomb
* 3000 baud was roughly 2400bps days
* 30000 baud gets us to ~28.8k
* 300000 baud was about 2 ISDN lines (2x128k)
* 3000000 baud is about typical cable these days (3m)
That puts us about another 4 orders of magnitude (3 if you count
FTTP/etc generally available enough to count 30m as "now") away from 30G
to CPE.
I'm sure there are more accurate timelines
