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 gotta 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 video 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 so thanks for watching guys you can
