Q: How is the internet connected among countries?

[ub4me]

Just curious.
Is fiber optic cable used for the connection intercontinental?
If so, does it mean that there are cables under the Atlantic Ocean between America and Europe, or under the Pacific Ocean America and Asia?
Thanks.

All of the above?

Yes, alot of it is fiber optic, and yes, there are many cables running through the ocean.

Above.net's Intercontinental Network

Level 3's Transcontinental Network

Lots and lots of routers.

 

I believe that they just redid the transcontinental line going to australia.

And yes most of it is just huge protected wires under the ocean.

how did they lie the wires? did a boat moving real slow just dump them overboard.

 

[dawks]

I believe they use subs.. one or two.. one to dig a small hole, and one to lay cable... and there is most likely a ship on the surface that carries cable, and feeds it to the subs. They are either manned, or remote controlled.. most likely remote controlled.

I just read about this here

 

[ricerx]

a lot of it is by satellites. asked my friend that works at the Covad NOC.

yes, there are boats that are specially equipped to lay submarine cable


LOOK here for maps ===> submarine fiber optic cables

 

[HamSupLo]

it amazes me how they can lay a cable across the pacific....that's like 5000 miles long.

i bet there are a crap load of optical repeaters down there!

 

[Aihyah]

think this months wired magazine had a page showing the undersea cables around the world. how many Gbps from each continentP

 

[ub4me]

It seems that both fiber optic cables and satellites are used for transcontinental network.
But which one was used first? And nowadays which one is used commonly?

Thanks again.
