100 Mbps Community Fiber Network: Howto

I am waiting to try to get fiber done up in my apt. i am lookign at how to get the whole routing and switching done right. right now i just have a couple itty bitty cisco routers and switches sitting here. i have two machines using fiber between themselves now. and i am hounding the phone company to allow me to get a bare line for 2 Meg dsl ... just gotta keep working on them. if i can i might be able to tweak this set up a bit more
a wise man once said "two wrongs dont make a right, but three rights do make a left" and that wise man was gallagher
This man is totally crazy. But how many time will this network stays up before local authorities stop it?

I read in the Media Section of "the Australian" newspaper about a town in Western Australia that was built from the ground up with the main goal being to make it the most connected town in Australia.
From memory (and I'm sure I'll be corrected) each house had a fibre optic connection.
If I can find more info on it I'll follow this up.

A 10mbps connection at our end is great, but there is always the bottleneck at the other side.
That is not to say that this is not useful, it is just that what is the use of having a 10Mbps line when the servers run on lower bandwidths?
Think of this, even if I have a T2, I really don't make use of my bandwidth when downloading a 100MB file from a 64K ISDN line.
Living in a rural area of Canada, I probably guess that we'll have honest polititians before we ever get any broadband out here from Bell Canada. (The prospects were good for Look TV but their financies are going down the tube.) If a lot of people around the world latch onto something like this, it could help kill diversified ISP markets - everyone would just be feeding off of super-fast connections from the phone companies.
The only thing better than having more than enough conduit installed before the area where you are installing the conduit is covered over and made next to impossible to get to is to have way, way more than enough conduit installed.
I see even classic Slashdot is now pretty much unusable on dial up anymore.
In fact, many of you would cry if you came back after a semester with Sunet's backbone. Places like Ronneby, Stockholm, Linköping, and Lund are well connected, and I am sure that I have missed a whole bunch of them (fill me in fellow countrymen).
;)
In fact, I wouldn't be surprised if a few of you tech students "over there" will start thinking about a semester in Sweden. Well, you should
And for all others, check up what 100Mbit/s equipment costs, ask companies to sponsor you, ask your schools for feed, and you too can have a useful connection to the internet. No more modem, ISDN, cable, or whatever. Sweet sweet ethernet. Can't live without it, can't, ehm, well, you want to live with it;)
this would actually improve community interaction.
Think about it. I know that it sounds silly, but if you have all of your neighbourhood on the same little network then it becomes much easier to do things like sharing files, playing games, and seeing when everyone's online, dropping notes to everyone to have that BBQ, etc, etc. I know that all of this can be done with the current internet, but having everyone on the same lan makes things a lot easier. I remember in University the dean of my residence was complaining that the networks that we set up were making us more antisocial, but the opposite was actually true. This was before we had internet in residence, and I set up an ICQ server on my machine and had a dedicated proxy out over my phone line and a 56k modem for email access (others allowed me to use their telephone lines and I had a cellphone anyways), and it was great to have everyone in the residence on ICQ at the same time, this was quite cool. We used to talk and use it to organize games and meetings and movies and the such all the time...
Oh back to the good old days. =P
If God gave us curiosity
100Mbps over wireless network seems pretty cool, but the article doesn't mention anything about the range at which those cards can operate at 100Mbps. IIRC, even the traditional WLAN cards operating at 2.something GHz, were having some problems with thick concrete walls. Now if we double the operating frequency, even the cubicle walls might be enough to block the transmission, on full speed at least.
This is the place where you write something that will make you seem like a complete idiot.
"Claim" is a bit of a weak description for a mature product. C'mon slashdot. Proxim's 100Mpbs products and technology are well over 1 year in the field. And BTW, not only can they do 100Mbps full duplex in the unlicensed 5.8GHz ISM band, they also run two wireless T1 interfaces on top of that -- between the same pair of radios. It is an absolutely wonderful solution for bringing branch offices up for voice and data. The interfaces fall back to 48Mbps and finally 12Mbps at the maximum range (~15mi with 30dBi antennas) but they always maintain full bandwidth on the T1's.

Everything slower than 10 Mbps is just a toy!
Is this post a flamebait? Sparking envy to those who live in an area where bandwidth is tight? In Indonesia, 28.8K is a very good connection. 56.6K is a bliss. ISDN is owned only by corporations.
Please people... You can boast your new super duper whizbang 10E100 bits network or whatsnot, but don't taunt anyone... It can cut real deep at times... OK? Thanks for your understanding...

This kind of networks surely points at the need for faster hd's. It's your hd that limits the speed in cases like this. I tested using two computers (with 128 and 256 MB RAM) with 15 m cable between, both had a IBM 7200 rpm IDE-drive and a 100Mbps Fast Ethernet PCI-card. I reached a maximum of about 70 Mbps, sending a 15 MB file. But of course it will be lower of you send alot of small files. And notice that this test were made for a line without other packets running around in it. On a 100Mbps net you will get a much lower speed because of all the collissions that occur when several people sends stuff at the same time.

All 100Mbps and no play makes the hd a dull boy

Sweden has actually a plan to give every home broadband access, just like telephone and electric power. Though I haven't seen much of it yet, but they are digging fiber all over the country.
Myself, I live at a student-complex in Trondheim/Norway, and here 100MBs is included in the rent :) We've got 100MBs internally, connected to gigabit switches. We got 1 gigabit to the university, and 3,5 gigabit to Oslo (where the rest of the world is linked).
Actually there is a total of 8.000-10.000 students living at such complexes here (of 20.000).
The only problem is that the world is too slow :(
"The assembler gave birth to the compiler. Now there are ten thousand languages." - Tao of Programming
Ok, the article suggested that 100Mbps is too fast for the HD to handle, I would know since I only get around 50Mbps between two computers with 100Mbps at home but 10Mbps is way too slow to transfer huge files between computers. The connection is completely useless if the other end couldn't handle anything more than 1mbps. 100Mbps connection won't do you any good at all but it is sure damn nice for bragging :)

Sorry, it should be Mbs (eventually Mbits).
Explain to me what the US thought it was "to expensive" or "to hard" to actualy get fibre going?Hrmmm 10grand a city +10dollers in tax on each house OR cheap ass modems that'll be obsolete in 5 years?
I moved to Sweden three years ago, and the use of the Internet here has always been ahead of other countries. I live in an appartment run by a large communeral organisation and we have had a broadband network installed. Thay have wired up a 100 Meg network with a connection in every appartment, the installation was free and it's about $20 a month to get connected.

We have a MAN (Metropolitan Area Network) Called Bitnet, Borlänge IT Network (http://www.bitnet.net/) comprised of about 70 kilometers of lit fiber, and 300 kilometers of empty tubing waiting for future fiber. Neighbourhoods are connected with either straight fiber into the homes, 100Mbit ethernet (copper), or 10Mbit ethernet. My house is connected with 2 fiber pairs to a switch in the basement, providing me with 10Mbit ethernet access (probably to be upgraded to 100Mbit within a year), I have, like those in Umeå, full bandwidth within the MAN and on SUNET (Swedish University Network), we have a gigabit uplink to the local univ, providing peering to SUNET..

Oh, well.. I'm heading to the office now, also connected to bitnet, but at 100Mbit full duplex, so I never have to write cd's or bring floppies, I just leave my servers on here and access them in any way I like from work, att full LAN speed.. Quite excellent.
Thank you.
So they are some of the few lucky ones that not just have 2 inches of dirt before hitting solid rock. ;-)
There is a good thing about using fiber this way. With so many "home" computers, a lot of them are bound not to be properly grounded. And you could end up frying a lot of hardware. Using fiber is great in this way, then you are the only responsible one for shocking your pc. :-)
This i why i hate cable tv. sigh. Have toasted the video out on my Gforce card.
One of my servers at home is a FreeBSD 4.1 running on a 166mhz Pentium. The harddrive are a 10GB 5400 speed Samsung(I think). The IDE controller does not support any fancy new IDE standards(and the BIOS didn't support a HD that size, but BSD just told me that my BIOS was fu..., and that I should use its parameters).
Anyway, from this old machine I can keep a steady 5.4MB pr. second.

In our LAN here at Umu (in Umea of course) we have about 1-2 ms for ping:

round-trip min/avg/max = 1.1/1.4/1.7 ms

Pretty nifty stuff.
Q.Who is really interested in this sort of thing?
A.Kids who want to play games and spend hours
on IRC and download porn pics.
Can you really see many adults give a damn about
this sort of thing going "Whoa dude , man , nice
fibre optics. Whats da bandwidth maaan?".
Unlikely. When adults want to socialise they
generally actually get off their arses and go
see their friends down a pub , not sit in front
of a PC getting a headache.
heh.. yeah, swedish humor is more "abstract"
'are we here to drink, or here to talk'".
after living here for 3 years.. and, after many sweden to finland cruises... it makes sense..
100Mb full-duplex connections to every home in the neighbourhood, $10/month for access (plus the initial set-up fees, which would really be worth it IMO) and connections to a gigabit ISP? That would be heaven compared to the paper or plastic (cable or DSL) choices in my area... neither is reliable, and connection speeds vary considerably.
The hardest part about setting up something like this would be to get your neighbours involved. The people who are into computers would be easy to convince, it's the luddites with no future-vision that would hold up the project. I'm impressed, very nice job. I think you've also earned the right to taunt the cable and dsl users living one street over =)
With all the stories of fiber-laying companies having hard-times ahead it's nice to know that there is at least one foreward-thinking ISP in the world (even if it's not in Canada).
Is it any wonder why Look TV is having difficulty with financial strategies like this:
"Due to overwhelming demand, we are no longer taking orders for our High-Speed wireless Internet services"
They are a product of the dot-bomb industry. Imagine if Dodge said "Due to overwhelming demand, we are no longer producing the Caravan". Uhhhhhh... Wow... To say the least.

We are constantly seeing stories of people who are pulling neighborhood resources together to get networks going. I think this is great, but I also think that these people are pretty lucky to live in such good neighborhoods as well. I could never have such a luxury because my neighborhood is really not well suited for the task. I live in a small neighborhood that is borderline suburbia, and is very close to a lower income neighborhood, I doubt it would be easy to pull resources in my situation. However, I guess that is the big trick, along with securing the high speed pipe. Also, this person is lucky to have a common community owned building to store the equipment which gives a sense of community ownership to the network.
The distance between Uppsala (where ftp.sunet.se is located) and Ludvika (40 km south of Borlänge) is around 165 km, so I guess the distance between Borlänge and Uppsala is around 185-190 km.

Many people believe ftp.sunet.se is located in Stockholm, which can explain some of the errors in calculating the distance between Borlänge and ftp.sunet.se

Everything slower than 10 Mbps is just a toy!
You may notice that many people didn't feel insulted or taunted by this remark, especially western cultures, mainly because most westerners don't take these types of remarks serious for a number of different reasons.
1. It is usually impolite to brag in Sweden, (people just call a an asshole in the US) thus a remark like this usually implies some irony.
2. "Everything else is just a toy" is often a parody reference to a sales and advertising culture.
3. Tech people are known for boasting the quality/benefits of a particular technology, whether or not they actually own it. (This is especially true of backbone technology. People will brag about technology it is impossible for them to own) This is also usually one of the most effective ways of advacating a technology when talking shop.
I'm sure the last thing the guy wanted to do by putting up his website was to spark bandwidth envy, but rather inspire people to take on similar projects.
Usually people who undertake projects like this often have utopian dreams and plans on how to wire the world, and I'm sure this guy was just making his point that people shouldn't settle for less than 10 Mps when the technology is clearly available.

Sorry to have to point this out as an AC, but it's called "soil" not "dirt". Dirt is an American misnomer which we are working to fix, but the misuse of the term seems to be embedded into the minds of the working class quite firmly, sadly.
I dig trenches for a living. These are used for AT&T Cablemodem/Digital TV lines. I'll tell you this; one person with a self-propelled trench digger would be able to dig 100 feet of a very suitable trench in 30 to 60 minutes. The cut in the ground would be about 8 to 10 inches wide and the mound of soil beside the trench would be just a few inches high. Another person would be able to lay the cable in and cover it all up within minutes. Our 3 man crew does 4 homes a day - 20 a week. We could have done the whole town in 3 weeks without any heavy equipment and without destroying all of the lawns. These guys in Sweden may know their tech but they made the laying of the cabling look very hard. No wonder the installation cost was so high - it should have been a fraction of the cost of excavating if they had done it intelligently. That shovel excavator was absolutely the wrong tool for the job.
I wonder if he had to get it ok'd by the city to run cables. Knowing the beuracracy(sp?) found in the US...the cost of installing this would skyrocket due to city permits and such. Did he have to cross any streets?

What we need to do is educate housing developers. They do see that improved network access adds to the value of their product. But they usually think in terms of DSL or (if they're very bold) Ethernet. If more of them knew how easy it was to include fibre networking in a new housing development...

You should move farther outstate. :) We have DSL available all the way up to the exchanges along the Canadian Border (Lancaster, Roseau area, etc.) and we're offering wireless in Warroad (which means you could at least theoretically get it out on Lake of the Woods) PLUS we have fiber to four islands out in the lake, which all now have DSL. So yes, there are islands in Lake of the Woods that have fiber to the CO and DSL to homes, and yet some people can't even get it in the city of Minneapolis. Weird.
