Explore how fiber optics uses light to transmit data over long distances, and with integrated photonics, expands our virtual world beyond the internet.
--
In 2012, a team of researchers set a world record, transmitting 1 petabit of data- that’s 10,000 hours of high-def video- over a fifty-kilometer cable, in a second. This wasn’t just any cable. It was a souped-up version of fiber optics, the hidden network that links our planet and makes the internet possible. What is fiber optics and how does it work? Sajan Saini explores the vital technology.

This video was accurate up until the 2:58 mark..... 1.) Most data centers moved to fiber optics between server racks years ago, with some racks using fiber optic exclusively for high bandwidth applications. 2.) "Integrated photonics" is currently a pipedream next to everyday quantum computing, way too much has to happen before we can use the technology, like figuring out how to build it. 3.) We have a technology to convert electricity to light, it's called a modem. 4.) Researchers maybe working THz tech, but we have enough issues with day to day 60Ghz wireless, to the point, it's not used commonly yet due to pitfalls. Also, the THz spectrum is approaching the visual light spectrum. You'll need more more power as you go up to get the same results, like 300x ~ 1000x the power of used by current Wi-Fi. Also, while using that much power, it won't be able to penetrate anything whatsoever. 5.) Good luck running fiber to all those nodes that will provide coverage, even if you could convince a large Telecom to pay for that bill. The FCC or equivalent government bodies would have to give up all control on the spectrum in use and where nodes could be placed. 6.) 6G, lol, come talk to me in 25 years, then maybe we'll be there. We still haven't finished 4G, the original standard called for 1Gbps, you're lucky if you can get 2.5% of that.

Came here to say this. #2 is the big one that had me going "wait...wtf is he talking about?" because...he's referring to photonics in general, not integrated photonics. Literally all fiber requires using SFP modules, but that doesn't mean we can somehow unplug wires everywhere. Even if ALL processors WERE made of integrated photonics, you'd still have to run optical amplifiers, and those still require power.

Interesting comment, perhaps you were so eager to watch a video whose content you know so well to prove it wrong, the video simply stated facts but never anything in concrete and I personally didn't finish the video thinking that 6G will be a possibility any time soon. Again, your comment is interesting, it does not, however, make the video inaccurate

Two facts I am critical of are: 1. the limits of fiber optics. The biggest limitation of fiber optics is “modal dispersion”. Submarine cables do not simply connect one continent with another with a single long cable. The cables are actually many short sections joined by repeaters that amplify the signal. Repeaters are required every 100 kilometers, or every 50 to 100 miles. The cables include electrical lines to power the repeaters underwater. 2. The narrator states that computer servers are overworked. This is a characterization that is both undefined and not supported. Servers infrastructure is always being upgraded as a normal part of technological demand and growth.
