- 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.

Whoa, it's almost as if this channel can answer any inquiry that comes to mind.
Indeed it is one of the most informative and well researched channels on UA-cam, do check out Kurzgesagt channel as well(if you haven't yet)
BTW glad to see a fellow Fullmetal fan...
Hey, are you a FMA(B) fan?
@@anitanaseer1007 are you asking me? If yes, then yeah I am a fan of FMA(B)
Can you made video on Indian god
I got u to 1k
I’ve watched your animations since I was 6, I found your channel on my moms iPad and made it my goal to watch all of the videos you already had posted. I watched every single one of your videos every time they uploaded. Until now. I’m 12 now.
That's great. You must be a smart 12 year old. Keep it up!

The narrative and animate are top notch as always. Inspiring !!! Hope we get 6G sooon lol
@Dominotik Ivan Tulovskiy That is why i mentioned "soooon"😂😂😂
First i need proper 4G speed 😂 100kbps

@Dominotik Ivan Tulovskiy i thought it means later
We have to get 4G first
While we're all in lockdown and can't see each other in person, I've been video calling my dad every weekend. I'm in London and he's in Singapore, and it's almost unbelievable how little delay there is, given that it takes a person 14 hours to fly that distance.

That's a long way this video had to travel before coming to my phone
some say the fire, wheel and electricity are the most important manmade inventions. i agree and i think the internet should be up there with them too
天吉Mark Yes
Man didn't invented the fire, wheel nor the electricity; he only discovered them. As for the internet, this is his solo invention
@@silviusaran yes
Silviu Saran true
And air conditioning as well :)
The animation, as usual, never disappoints. It almost feels like it's getting better and better!! Every animation team understands the brief so well, and they just know what the subject matter needs. Well done again, Ted-Ed!
Please give a watch to freequraneducation they do amazing animation too
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
I mean.
We have finished 4G.
With 5G.
You haven’t seen the ads?
There is 5G already used
Nice comment and thanks for pointing out the wrongs.
Thank you 🙏 so much for this video
I’ve always wondered how the internet was made possible

It still amazes me how humans managed to capture audio,photo/video and transfer them around the globe in the form of electromagnetic waves...so magical
Thanks Ted-Ed, your videos are always so nicely presented and great to watch. New Zealand isn't on the map at 2:46...
Again..

Wow Ted-Ed never stops amazing me. Thank you!
Watch freequraneducation they are on another level of animation and u will surely enjoy
I honestly learned much more from TED-Ed rather than school
Because you didn't focus in school

I'm so happy on seeing that person so happy
Idk why😀😊
@@randomdude9135 Also that professor from the five-sided square video. Look him up plz, he is really excited about his subject.
Ted i have a question. What if all the people decide to sing all together. Same tiem and same day what's gonna happen. Whats the hight of the sound wave can rich
The Earth is so big. And we humans are so small. Nothing special would happen. Wouldn't even notice.
Also, sound can not only increase but also _decrease_ the height/amplitude of the sound wave, due to interference.
So, that project to turn heat energy into renewable electricity would have been great if successful.
I never missed any Ted Ed video, and this one is definitely one of my favorites. Thank you so much for creating this amazing content!
Hello The Odin Project gang.
hi
Ted-Ed always saves my sanity here in UA-cam.
History of humans and light:
1. Fire
2. Torch
3. Gas lamp
4. Light bulb
5. Internet
I love TED. Every video puts me into a new perspective, whether it's a talk, riddle, or Q&A.
Thank you Sir Tim Berners-Lee for making the internet free!!!! 👍👍👐👐
Making it understandable to public is a real hard work thank you so much
I had no idea they were all on the ocean floor! I mean, now thinking about it, that makes sense, but still way cool!!
Who remembers when 2G was amazing? How fast we've grown.
And now there's 5G
COMPUTER TECHNOLOGY + ENGINEERING + PROGRAMMING =LIFE
Is hacker have a life?
4:35
So, is 5G already obsolete?
No, 5g has only been in the experimental phase. First use was for this year's final 4 by Verizon.
And these photons chip or whatever are not really a thing? And most data centers are using copper cabling in rack, where fiber optics are used everywhere else including between racks. Sometimes, in rack cabling will be fiber.
Hey I have a doubt. Why our normal PC's can convert light signals to electric signals and big servers can't do it?
Terjemahan Indonesia dong please
Love is an AGI made of people that is just as good at killing the normal people who created it.
What makes the ping increase when you conect to a farthest server? Are those milisecond of ping the distance in speed of light between the server and the PC (by going zig-zag)?
So satellites don't transmit mass amounts of data across the globe?
Is it fair to say satellites carry a fraction of the data underwater cables carry?
U didn’t tell about the inventor of optical fibre.He was an Indian and name Narendra Singh Kapany
Always, always, and always a very clear & interesting narration and outstanding animation.
This channel makes me addicted to watch over and over again their videos. Keep up the good work, wish someday that I'll be able to be a part of Ted Ed team 😊

You animation is amazing 😋.
Don't pin or give hear in this comment . If you are not bot.
TED-Ed , please don't change the style. Animation, background score and narration, they together give an experience of a miniature "feel-good" movie. And knowledge and information, they are bonus.
be carefull guys

I mean who are these people who dislikes Ted Ed's videos.....
I only have one question: how those glass “cables” where put around the world ?
Boats
Indian is the inventor of fibre optics his name was kapany.
Thank you for this video, because I was stuck in this topic for 2 today's and when I see is five minutes video the concept was instantly clear by this animation... Thanks a lot.
please ted ed add indonesian caprion!! love ur videos

I had this question in my mind almost forever. Thanks for answering it . I love Ted Ed.
Did you also think of this question before ?? Like if you did.
Copper to Fibre Optic: Why you come so fast?!
But it can break too often
i should be doing homework but this is far more interesting
ha. so we basically communicate with light.
How are there dislikes???😔 keep up the good workTed Ed love it!
There are twenty already!
One question: when’s the next Ted-Ed riddle coming out 🤔?
Amazing video, learnt this phenomenon in school recently! Great to see how this translates into real life
This is why UA-cam is not dunk, the light is tooo fast
Please make a video about how internet cables are laid through the oceans around the world.
Yes yes yessss! I would love to know how do they do it too! 😌
Love You from INDIA✌🇮🇳
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.
Is it only me or this topic of total internal reflection (and optical fibres) I have studied in my 11th class.
all i know is that the internet runs my video games
I thought photonics was going to replace silicon chips. Perhaps that was just overhyped by the media.
I have a question.
How can you put data/information in light?
Like how we transfer datas using rf and etc?, to make it simple it's like using flashlight to communicate morse codes, it involves modulation in the transmitting side(translating evryday language to morse code) and demodulation in the receiving side (translating morse code in evryday language)
Eh, this won't make life any better, just faster. Thank you for the info though.
Why not cover the glass thing with something like rubber so that even the glass is very bent, it won't leak?
Is my idea even correct?
Graphics By: Aztrix the rubber will probably absorb some of the energy
AHEM 0:12 It was NOT a petabit of data, it was a *petabyte*, which is 8 times larger.
@4:36
6G? We even haven't perfected 4G while 5G is still in its infancy.
where u from? i got perfect 5g since 2012. Romania rullez!
it's merely a hyperbole to express super fast internet
If you happen to come to this comment any time after 2020, you may or may not be thinking of "Karens".
i like ted ed giving useful and unique information
Wish I could join you guys so that I can learn and also make learning possible. I've no clue how to do it....
rayyan ahmed you can contact them through their website :)
Great animation as always
Oh thats why i can able to use vpn to watch..........😏💏
I just spent 3 years for graduating in ELECTRONICS HONOURS DEGREE & read all this...
Now I know I could have got that degree only in 5.19 minutes.
You might want to put a seizure warning at the start of the video.
Many Data sets Have an Approximately linear Relationship between, Variables. We can Predict 1 Variable using, a 'Best Line'. a Best Line known as,
y=mx+b.
It follows all the Trends of, The Data. This where, X is Called, 'The Predictor Variable'. Because, It is used to, Predict Y. While, 'y' is often called the 'Response variable'. This technique is Called, 'Linear Regression'. Even though, It is Simple in Machine learning, It is, Suprisingly Powerful...
Also, 84÷6=14. and,
π=3.141592654.
m=n^2
Where, 'n' is, a Simple number. The 'm' is, a Full-circle Number.

So basicly: Fibre-to-the-Home, wich enabled Routers with TerraHertz frequencies and a maximum distance of 10 metres to send data fastly ... Yes, we're on it - i'll just take a long time
In other words 5G, All they have done is transfer the expenditures from network cabling to high bandwidth WiFi chips, new antennas and high power electrical cable ( copper ) in your neighborhood every 100ft. Transmitting in microwave frequencies.

Hey world! im from Australia, just wondering what is a fibre optic? a few years ago we upgraded to copper wire, cost the government something like 51 billion dollars 🤣
Narinder Singh kapany,the indian-born American physicist who invented optical fiber,also known as father of fiber optics.

Probably shouldn't have used Perth and Melbourne as your fiber optics diagram considering our government butchered our broadband network.
