View Full Version : US to Europe connection?
How is the US and Europe connected? I read here (http://www.ieeaf.org/news/news_092002.html) that we're connected ona 10Gigabit connection, but it doesnt explain what kind of connection. Is it Satellite or a line under the ocean or what?! I'm interested and can't find much in the first 5 pages of a Google search :(

I say its sat. People even here in the US can get a 3meg connection using sat. The latency will suck, but the throughput can possibly be better than a dsl/cable in the same area.
how the hell can satellite get 10gigabit/sec???
I know of someone who has/had sat. connection. same rated bandwidth as cable, but he could get no less than 800ms in game servers. im downloading a game from a european server and my latency is 140...if they are on sat. it should be 800 by your logic.
and by the way, lower latency does provide more bandwidth, at least with ram. its been proven.

my vote is a line, under the ocean.
it's a guess of course, but i'd bet my toes that it isn't a sat connection.

more bandwidth, because there is less waiting for the next bit/packet. lower latency will provide a higher rate of speed on an in out in out in out in out setup, like ram. But, if you are transferring a large file, it won't matter if your latency is 1ms or 1 second, because the bits/packets are only going in one direction, with the common "did you get that" packet in between the two computers.
the latency is still an issue though and does provide more bandwidth. even if your just downloading. its sending it in several small packets. to send each it has to go through that latency cycle, so if its slower, aka satellite, its going to take longer.
Its a oceanic fibre line i belive bc its the speed of light transfer.
It must be something of a lower latency that Satellite. Im in the UK and if I ping, say, www.overclockers.com, I get an average ping of 96ms.
I also doubt there is one single connection. I would bet the main connection would be some sort of undersea cable, with maybe a few sat links as well.

My Cisco teacher said something about them using lots of fiber. There is 10gb fiber (OC192) so that option seems the most reasonable. I cant ask him tho cuz I won't see him til school starts back up for me in Aug..
Plus the sat way isnt possible, latency would be sky high. Plus I dont think the current technology for sat. is anywhere that fast.

Ok, my bad. ;)
interesting topic. whenever i dl from european or asian locations to the dorm here, speeds are at 4-5,000KB/s but i've always wonder if the connection was through air or by land.

I think you mean Sea. :p Sorry, couldn't resist...

How do you lay such large wire underwater through such a big distance without the risk of having any seismic activity destroy the cable? I've always wondered how they did this myself. There must be multiple lines if they do run it under water. I think satillite would be a more reasonable method, but then again it seems like there would be quite a load.

I don't think its just the fiber optic cable going under the sea. Its probably in some sort of re-enforced enclosure that keeps it air/water tight. I would like to see some people that actually know about this reply, I was 99% sure there was an under-water "cable", but I wasn't sure what kind or how they did it and that sort of thing.
this would make one hell of an intresting show on the disc/tlc channel...*calls disc to sell the idea* hehe :D

man that would be expensive for that much fiber optic cable to go under the sea.
It is a bundle of Fiber optic cables to be exact, 3 of them if I remember correctly. I saw it on the discovery channel. Takes them 4 months to load the cable onto a ship.... its ONE peice long enough to cover the distance, all wound up into the hull. Its burried under a few feet of sand near land but out to see its just laid ontop of the sea floor. They plan the route to be on the best terrain, its not a straight line. I think they left a little slack now and then incase things moved down there. Its hard to go into much detail on an hour long show, I'm sure they'll probably show it again sometime.
only the government and the companys who lay the lines know where thier at and how many there are, they keep the info private for that people cant go out and cut/damage the lines.

There is a website that shows pretty much exactly how the fiber optic cable is laid across the ocean. I believe it is buried for the first part and once it gets to the flat part of the ocean it is just layed on the ground. I will search around the net and try to find the website that describes how it is done and everything.

Couldn't you just imagine a bare little Cat5 cable running along the bottom of the ocean. :D
But really, isn't that just wierd that they can make a cable thats long enough to go from one continent to the other. Isn't the ocean like hundreds of miles deep. Think of how much pressure would be pressing down on that.

lol you know what i meant. didn't forget bout those big masses of water. if its buried my statement about land is still correct.

Yea, but also when you think Cat5 cable has a max length of 300 (ft or yards or meters, i forget, but whatever) before it starts losing data. Imagine how heavy duty that cable must be, all that pressure on it, and it doesn't lose the data at those intense distances.

There is no "flat" part of the ocean. In fact, there are big "mountains" under the sea. Theres one in the middle of the Atlantic Ocean, inbetween North American and Europe. Its called the Mid-Atlantic Ridge. The "mountains" in the sea are much much larger than the biggest on land. The Oceans have the deepest valleys and the highest mountains, much larger than those on land.

I can imagine it was very expensive to do, but they (governments) felt it was needed and I'm glad it was done because it allows the people of the world to come closer together and learn more via the internet.

The beginning of an article states that its a 10gbit link dedicated for research purposes its not for general use, think Internet2.
According to here (http://www.telegeography.com/ee/free_resources/gig2004-02.php) there is about 400gbit of undersea bandwidth between North America and Europe. As well the deepest part of the ocean is 11km deep, and i'm sure they advoid trying to lay cable on that part ;)
From here (http://davidw.home.cern.ch/davidw/public/subcablesv20.html) they run repeaters which are placed every 10km to nearly 200km to reamplify the signal.

Oh. :-/ I thought it was much deeper than that, well i guess 11km is pretty deep.

My uncle works at Cisco Systems, he said that Cisco has linked all the headquarters with their own fiber line. They do a lot of video conferences and their "internal" phone calls goes through them too. So if Cisco had their own fibre connection, I asume there is (at leaste one) fiber line between US and Europe.

I think I read somewhere that the cable for deep sea is about 1.5 inches in diameter and the shallow cable is 2.5 inches in diameter for more protection.
The first transatlantic cable went into operation in 1988 by ATT, I think and that was for 40,000 phone circuits.

The first cable was in place LONG before that, actually 1858 , read about it here: http://www.history-magazine.com/cable.html
One of the 'public' transatlantic links is run by a company called Pipex, the cabling terminates in the UK around Manchester in the North West and is then linked to the backbone networks. It is one of many fibre connections between the UK and the US with most of then terminating on the West coast of England.

Oh my god the first transatlantic cable venture was in 1857!

Ok i thought i was right with the fiber optics and boats. But I still learned a ton and thats some cool knowledge to know for the heck of it, lol. Its pretty interesting too with the 1st cables linked. Man that was along time ago..

There's gotta be tons of bandwidth between Europe and North America...
Edit: One example:

And there's gotta be a lot more from the rest of the operators..
