 Next today, there's a new project underway, an undersea cable system that will connect South Africa with Southern Asia, the Middle East and ultimately, the rest of the world.Though it will stretch for thousands of miles, it will account for just the tiny part of the vast intricate network of underwater fiber cables that ships have been laying since the 1800s.

Where you're watching this video, the United States, Europe, Asia, it's a cliche to say we live in an interconnected world.But, duh, we do.

And the global circulatory system that delivers 99 percent of international data from point A to points B through C and back again is made of fiber optic cable.Unlike copper cables, which transmit electrical energy, fiber optic cables transmit light.That makes them significantly faster and less susceptible to interference.Fiber optics trumps satellites too.They're cheaper, they're faster, and you don't get those delays.Fiber optic cables are very deep underwater, over 300 of them connect every continent not named Antarctica, and laid end to end the 550,000 miles of cable would circle the earth 22 times.

And, boy, is that good for business?Ecommerce isn't bound by borders.An international stock trade can be executed in a flash.You can video conference with colleagues in Florida, or France, of Fiji, not a problem.Take a ride on the global fiber optic network, and offices wired with the fiber network allow for speedy data sharing.So, we here at CNN can send our videos from one edit sweep to another really fast.

And consider this, thanks to fiber optic cables, innovations aren't bound by bandwidth.Remember trying to stream a video in the old days? Brutal.Do you think Netflix would even come to be with that kind of infrastructure?I mean, would you even be watching this video?

A mom in New York recently surprised her daughter at college by sneaking into a dorm room and snapping a selfie.Looks great. There's just a little problem.The mom says, Look where I am. Where are you? The daughter says, Where's that? I'm in my dorm.Then she writes, Please tell me you're not in someone else's dorm? And the mom promptly thought, uh-uh.We see this happens all the time, but it probably doesn't.Hey, at least the picture went viral.Will this shut the dorm on future visits?It was a mama's mistake.
