english: They stretch across the ocean. They're three or five or eight thousand miles in length, and if the material science and the computational technology is incredibly complicated, the basic physical process is shockingly simple. Light goes in on one end of the ocean and comes out on the other, and it usually comes from a building called a landing station that's often tucked away inconspicuously in a little seaside neighborhood, and there are amplifiers that sit on the ocean floor that look kind of like bluefin tuna, and every 50 miles they amplify the signal, and since the rate of transmission is incredibly fast, the basic unit is a 10-gigabit-per-second wavelength of light, maybe a thousand times your own connection, or capable of carrying 10,000 video streams, but not only that, but you'll put not just one wavelength of light through one of the fibers, but you'll put maybe 50 or 60 or 70 different wavelengths or colors of light through a single fiber, and then you'll have maybe eight fibers in a cable, four going in each direction.
non_english: Raztezajo se preko oceana. Dolgi so pet,  osem ali deset tisoč kilometrov. In čeprav sta znanost o materialih in računska tehnologija neverjetno zapleteni, je osnovni fizični proces presenetljivo preprost. Svetloba vstopi na enem koncu oceana in pride ven na drugem. Ponavadi pride iz stavbe,  ki se imenuje sprejemno-oddajna postaja in se pogosto skriva  v manjši obmorski naselbini. Na dnu oceana pa so ojačevalci, ki so podobni modroplavutemu tunu  in vsakih 80 kilometrov ojačajo signal. Ker je hitrost prenosa  podatkov neverjetno hitra, je osnovna enota prenosa valovne  dolžine svetlobe 10 gigabitov na sekundo, kar je morda tisočkrat več  kot vaša domača povezava, in je zmožna prenosa  10.000 video posnetkov. Toda to ni vse,  saj ne bo potovala samo ena valovna dolžina  skozi eno izmed vlaken, ampak bo skozi potovalo  50, 60 ali 70 različnih valovnih dolžin ali svetlobnih barv  skozi eno samo vlakno. V enem kablu bo na primer osem vlaken,  po štiri bodo usmerjene v vsako smer.
