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: Rastežu se preko celog okeana. Dugi su 5 ili 8 hiljada kilometara i ako su nauka i računarska tehnologija iza toga vrlo komplikovane, osnovni fizički proces iza toga je vrlo jednostavan. Svetlo uđe  na jednom kraju okeana i izađe na drugom i obično dolazi iz zgrade koja se zova "dolazna stanica", obično je ušuškana negde kraj obale i postoje pojačivači koji su na okeanskom dnu koji izgledaju malo poput tune i na svakih 80 km, oni pojačavaju signal. Pošto je brzina signala veoma velika, osnovna jedinica je  10 gigabita u sekundi što je verovatno bar hiljadu puta brže  od vaše konekcije kod kuće, a što može da nosi 10 000 video strimova, ali ne samo to, tu ne ide samo jedan svetlosni talas kroz jedno vlakno, već ćete staviti verovatno 50 ili 60 ili 70 različitih talasnih dužina ili boja svetlosti kroz jedno jedino vlakno i imaćete verovatno osam vlakana u jednom kablu,  po četiri u oba smera.
