Hi, this is Wayne again with a topic “What’s the Fastest Possible Internet Speed?”.
Thanks for watching tech, quickie click, the subscribe button then enable notifications with the Bell icon. So you won’t miss any future videos. We have gotten use to most everything having some kind of a speed limit. The roads we drive on the airplanes we fly and even the photons of light, hitting your eyeballs right now, with the latter being the most probable reason that we haven’t heard from et since he left. But what about the Internet? In just two decades, we’ve gone from 28 K connections to speeds of a hundred megabits per second being the norm and with demand for even faster performance and more connectivity. Thanks to a streaming, video digital game, distribution and Internet enabled smart gadgets. The question becomes: where exactly is the roof on this thing? Well, let’s start by having a look at the fastest current internet speeds, and I’m not talking about the handful of people in like Estonia or North Carolina, who have 10 gigabit connections at home.
You got ta. Think much bigger than that: the Internet backbone that forms the main highways for the world’s data, although there are plenty of routes that boast speeds of a hundred gigabits per second or even higher, that is actually child’s play compared to the most advanced infrastructure in the system. As of the time we shot, this video, the fastest portion of the Internet backbone, is an undersea cable called Moriah stretching from Virginia Beach to Bilbao. It can transfer data at an astonishing 160 terabytes per second, I mean that is about like every single person in Portugal.
Deciding to stream a 4k video at the same time and get this the cable isn’t much wider than your average garden hose. So how exactly does it move data so quickly? Well, you can learn more about what makes fiber-optic cables so fast in this article, but big undersea cables like Maria use optical amplifiers, at specific intervals, to keep the signal strong as it flows down the pipe. So just like an unamplified light from a cheap laser pointer. Won’T go on for ever and hit the moon. Light can get attenuated inside an optical fiber, as the materials inside do not reflect light perfectly scattering and absorbing it to some degree.
So, by using amplifiers, combined with using several fibers in one cable and multiple wavelengths per fiber to represent different data streams, these undersea cables can be tasked with carrying huge amounts of information. So back to our original question, though, can we go even faster? Well, as technology improves and we deploy materials that can reflect light more effectively and find more efficient ways of using the light spectrum, maybe by cramming more wavelengths into a single fiber, we could actually see speeds of over a petabyte per second and even higher on just One fibre and then you could actually multiply even that by several times, by putting several fibers into one cable. As long as the rest of the infrastructure can handle, processing and separating all of the different signals passing through it, and keep in mind that most modern optical networks use infrared light, which is relatively low frequency and therefore can’t carry as much information as more energetic high-frequency Forms of radiation, so in the future we may even see information carried via UV light if we can find an effective way to transmit it using materials that can stand up to its higher energies and keep it from being attenuated too much, though we probably wouldn’t want To use it to replace Wi-Fi unless y’all want a bunch of skin cancer, so the answer then well. You can always build a fatter pipe or use higher frequencies to go faster, meaning that in theory there isn’t really an upper limit that we can identify. Quite yet, but of course in the real world, concerns about cost practicality, signal strength, energy consumption and safety will provide concrete challenges, and do remember, of course, that your home internet connection will always be several orders of slower than whatever Microsoft is installing on the ocean floor.
So, despite the talk about petabyte connections, you might want to hold off on those plans to invite your whole neighborhood over for a 10,000 strong tech, quickie episode in 4k party, no matter how appealing that might sound. Speaking of appealing check out world of warships, the thinking man’s action game, not only is it free to play, but the game allows you to team up with other players to take control of real warships from across the globe. I mean not literally, of course, you’re not actually like controlling a real worship. Meanwhile, it’s like out there like firing, uh stuff. No, it’s not like that, but you can dominate the oceans with a naval fleet featuring some of history’s, most iconic vessels like the USS Indianapolis and you can unlock new ships as you play. World of warships features highly detailed models, weather effects and realistic battle. Mechanics to make you feel like a real naval commander, plus there’s always something new being added to the game. Every week since it launched over 200 ships from 8, different nations have been added, with over 7 million players worldwide.
So right now, new players can click. The link in the video description and use the invite code play warships, 2018, all caps to get perks, including 250 doubloons, a million credits 3 days of premium access and a premium ship, so go give world of warships a try today.
