- 99% of all internet traffic - from this video to your Pokemon Go account to your family WhatsApp group - runs on a hidden network of undersea cables. Why should you care? Because modern life is increasingly dependent on those slinky subaquatic wires. And they get attacked by sharks from time to time.

I think browsers like Chrome needs to update their animation when it comes to No Internet. Instead of dinosaurs, maybe use sharks that try to eat the internet cables.. underseas...
dinosaur game is og
And maybe build a shark game instead
Baby shark do do do do do do Baby shark do do do do do do Baby shark do do do do do do Baby shark do do do do do do Baby Shark!
dont you dare touch my dino game
I work for google. Ok, we will implement that
I've worked as a Datacenter technician for over 10 years. Whenever I'm sitting with non-IT friends explaining this concept...they are mind blown. Makes me feel so much better about my job security.
Do you see Elon musks satellites as a threat?
Hooow? One of the earliest fiber connections was between West Berlin and the rest of the Federal Republic of Germany.
🤣🤣🤣
@@chrisrosario6114 yes and no, Starlink as of current still relies on fiber optic network. What it does is solving what called as last mile communication, which is the communication from ISPs point-of-presence to the customer premises. Also just as any other wireless communications it is prone to shared bandwidth. In which could have significant impact especially on ultra high density area such as city center.
I’m glad to hear your pool of friends are idiots.
The fact that large tech companies like Amazon, Google, and Meta control some of these cables shows just how much they run the digital world
if u dig a little bit deeper, you'd also understand that even your local internet service provider are on it. example PH's PLDT
Well they are the ones funding this, in order to improve services.
no shit sherlock 😂
there’s not much they can do with it
what are you expecting.. joe blow to own a cable
It boggles the mind that "small" cables laid hundreds of feet on the sea floor can carry such vast amounts of data. That such cables can even endure the distance, and harsh environment of currents, saltwater, and apparently tech hungry sharks is a testimony to the engineers and builders. The world has come along way since the first under sea cable of the mid 1800's! My hat is off to all those with the vision and ability to make our tech world a reality!
hundreds of feet?, a few thousand meters!!
@@crazyyoutuberguy thousands of meters? Try hundreds of thousands of CMs and millions of MMs!
Are we sure they always sit on the sea floor and not suspended in some way?
3000 miles from the USA to the UK. It's incredible how it all works .
@@anthonyduncalf6190 And to think the first cable transatlantic cable was laid in 1855 with "reliable service" by 1866.
We never think about the infrastructure needed to have us all connected. Here’s a sentence you won’t hear every day. “My internet went down because it got bitten by a shark.” 😂😂😂
well restarting the router not gonna solve that
Imagine kids/students telling their peers, the couldn't do online assignments due to shark bit off the internet 🤣
If you are in America, then you only can read my comment that quickly because it went through these cables.
🤣🤣🤣🤣
Well its more of a lag, alot of modern equipment can reroute traffic if it detects a malfunction, but the latency will go higher, since it has to redirect through more servers.
"Cable is by far the cheapest and most efficient means of Yeeting vast packets of data over incredibly long distances" haha 😂
Lol
FAT YEETS!

it sounded so mainstream and collegiate. gonna have my kids sneak it into a paper for school and see what happens
I loved when i heard that lol
Good to see this because most people believe that they're using satellites or some other wireless technology when communication with friends and family in another country.
Satellites are a hoax. They never exist.
Even more fascinating is how everyone got involved with these cable laying projects. First, a large entity (telecom company/government) makes plan for the cable route, beginning with their home country, then they propose the plan to member nations along the way, these members would eagerly jump in to join the project by helping to pay for them. This is because every country doesn't want to miss the bandwagon of data connectivity, so they join as many cable projects as there is in their locations.
I heard a great story about tapping into undersea cables from a guy in the repeater business.
Back before Gorbachev, the CIA was interested in a Soviet Navy cable near Vladivostok. They knew the cable existed, just not exactly where. Obviously poking around so deep inside Soviet waters was going to be hard to do without raising suspicion, so they needed a shortcut. Somebody said in a meeting "It's a cable just like any other cable: they don't want it damaged. We should look for 'No Anchorage' signs close to the coast."
-sure enough! They found it this way.
Actually, this is common knowledge: if you do a little Googling something like "Vladivostock soviet navy cable cia" (or something like that), you can find the story for yourself.
How it became common knowledge is eventually the Soviets got tipped off, and found the listening device.
-Today it's displayed in a Russian museum!
@Varun Mehra the new drug may be. Because some people actually are able to perfectly live without internet, but those who are addicted to it will get mad in its absence.
@Varun Mehra as I said, there are people who can actually live completely offline. Me, for example, I'm pretty close to those, I'm in the middle as I only use internet to watch some videos from time to time. The rest of my life occurs as a completely offline thing. No social networks, no downloads or update needed, as my workstation (DAW, 3d animation, IDE for arduino robotics) all work offline, even my maps as HereWeGo are offline apps.
Once downloaded (in an internet cafe) I don't need connection at home.
I never updated my systems since years so far and I perfectly work everyday at no rest. Absolutely offline.
@@Carolina-mw4po I think you missed the point Varun was making. You may be able to survive as an individual without the internet but other services you use like public utilities, roads, telephony and much much more are all connected via the internet. Modern society collapses without it. Unless you are living on a farm stead that is completely off the grid you rely on the internet and the modern conveniences it bring with it.
Operation Ivy Bells.
I knew that there were optical cables running down the ocean . But I didn't knew about the mechanics and the hard work put behind these operations. Thanks for the video
Yep!
There are ships around the world on standby 24/7 to locate and repair cable faults / breaks,
looks like I have been living under a rock, I thought we all communicated through the internet by radio waves or something not underwater cables lol
So you just thought they were put out there by a wizard?
@@MrMcSnuffyFluffy maybe if you believe in wizards and I think modern science is not less than some sort of wizardry
@@MrMcSnuffyFluffy I did.
This man really used the word "Yeeting" in a documentary-style video about telecommunications.

Wow, this is something you never really think about while using the internet. It's amazing to see how much work goes into it and how complicated it is!
its completely mind blowing
It's also very interesting to see how rubber plants and the acquisition and growth of them changed the world for supplying rubber to coat undersea cables long long ago. A story of human rights violations too of course.

@@manzidelick2752 why do you seem to have a need to portray me as such?
Hi, there is a relatively small mistake in geography( 0:38 timecode ). Black Sea is located next to the Caspian Sea on the left
So the phase should be like:
The relatively modest 300 kilometer Azerbaijan to Turkmenistan wire running under the Caspian Sea(NOT BLACK SEA)
exactly what I was gonna comment
Yep, he's got the correct continent so it's small in this context
I noticed that too and IMMEDIATELY scrolled to the comments
I'm surprised that I missed that. I'm tired. Thanks !!
I noticed immediately and scrolled through the comments to make sure if anybody else noticed lol
I just tested my 1 gig fiber connection with Tokyo and Moscow, it's amazing how simple it is to receive and send data thousands of km away, over those undersea cables!
5:28 "For now, cable is by far the cheapest and most efficient yeeting vast packets of data over incredibly long distances, fast."

I intern at a datacenter and my eyes litt up when he mentioned DWDM, its a big concept here and we are implementing it in a variety of ways. Great video!
The 100 Gbps turning soon to 400 Gbps is actually per wavelength, meaning the overall bandwidth can be up to 80x that. Plus, that is only if you use one fiber strand. These fiber cables should have dozens of strands of fiber, thus multiplying the amount of bandwidth even more.
Exactly. These cables also have self-healing measures/materials that often don't require human assistance to stay operational.
And I get 20 Mbps at my house…
Thank you for clearing that up I knew something was wrong about that figure
@Nom Flo Not quite, at my home I have 10Gbps FTTH technology for 15$ per month. That's in Romania by the way.
Do we know if the repeaters are passive? I'm guessing they should be so so that transceivers on either end is that's required for an "upgrade" both now and into the future.
Or perhaps each repeater can be programmed? (doubt it as super $)
The amount of things that need to occur at all times to sustain our way of life that no one has any idea about is astounding.
Watch the social media addicts shrivel up and die in a Global internet outage.
also, the more complex a system is, the more vulnerable it is to failure
Stuff like this is exactly why I got into IT, technology is fascinating and your average person has no clue how much insane work goes into making everything we use on a day-to-day basis possible.
I always wondered how internet got across oceans, this answers a lot of questions.
Eventually they'll be obsolete for better fiber with better reflective surfaces etc but for now, the only changes will be the end equipment (equipment at each end) and the repeaters to allow faster operations of each wavelength of light.
I like the fact you mentioned the different wavelengths (multi-plexing) where you can have non competing "colours" of laser light beaming down the same glass run (they bounce down the cable at differing lengths so don't mingle/confuse). It doesn't actually do anything for your "speed" but it MASSIVELY increases the throughput because instead of say 1000 people sharing a single core at the same time, 200 might be on blue, 200 on green, etc meaning the shared connection is not bogged down as much (where you might get the speed illusion from).
exactly and we have a long time before this system becomes obsolete.

Now you realise that “in the cloud” actually means “under water”…… my maternal family were all Cable & Wireless people, trotting about the globe from one cable hub to another….. a cousin followed in the tradition, training at Porthcurno Valley in Cornwall, where the cables came ashore and the Cable & Wireless Engineering College.
The small cable hut still stands at the head of the beach and you can visit the Telegraph Museum nearby. I remember marvelling at seeing a cable that terminated in a hut on a Cornish beach, knowing the other end was in India 🙂
Cool but I don’t remember asking
Love from India
Not really, the cables aren't really data centers. They are more like just a means of transporting the data. The data centers are still on land somewhere.
@@agoogleuser9102 you never asked plus stop being rude man.
So this co insides that the earth is flat. Because there are no satalites
Id like to think a shark bit into one of those wires and was instantly filled with 10 terabytes of internet and is now creating a underwater base as we speak to begin his evil plans. And he wears a monocole. There has never been a more perfect villian.
This was once my job for 2 years and it was fun to be part of this great job
Never knew how real my red stone contraptions were in Minecraft until I heard they really use repeaters I’ve basically been a electrician and a constructor
Lol can u elaborate?
@@MrVaDelux what do you want him to elaborate on? Pretty straightforward.
Agreed. I'm gonna take my redstone knowledge and build me a elevator by my garage
@@Neon-ws8er Actually, no.
@@MrVaDelux there’s a material in a game Minecraft named redstone. It’s basically a simplified version of electrical wires with which you can make simple mechanisms like automatic doors, farms, trapdoors, storages and other things (some madlads made even simple computers). Redstone has a certain amount of power that diminishes with every block. If you’re making a longer redstone trail you have to put repeaters every dozen blocks to amplify that power again. Similar thing was used in the video and that’s why he’s making a reference to it. Hope it helped!
Sharks like "damn this eel is hard as hell."
My uncle used to work for AT&T on fibre optic cables, mainly in the Atlantic ocean, but he essentially covered half the world with his counterpart looking after the other. As a child of the 80s I thought that was the coolest thing ever.
I worked in the past with ATT Transoceanic. Very interesting cables Fibers were stripped with hot sulfuric acid and fusion spliced. With periodic repeaters housed in beryllium alloy housings,.Powered thru the cable from each end.Fiber can be "Tapped" but it causes a noticeable loss and direct contact with individual fibers is required. Very difficult to do on the bottom of the ocean.. There are multiple fibers in each cable. As I recall they used 9 um cored fiber.
Wow im shocked have been led to believe its ALL SATELLITES ...lol ...sarcasm implied ...jeez....
Wire is always faster.
Satellites run the television network, and the internet to some extent, only for isolated places. Rest is wire.
@@doctorpanigrahi9975 Wire is actually slower, it's the capacity that matters.
@@doctorpanigrahi9975 it's not wire it's because of optical fibre which carries signal at the speed of light
@@whityguy9570 I have never seen a white person in my entire life.
I learned about undersea cables when I was in high school... I had a part time job and when I came into work after school one day, most of the staff was gone. I learned that the undersea cable had snapped due to a massive earthquake and all emails to Asian servers were being returned as undeliverable. It took about a week to fix the issue.
In the communication world they call “repeaters” LE’s or Line Extendors, they also have higher output ones called amps
This is mind blowing imagine having to go put on a suit and descend hundreds of feet in the ocean to repair such cables wow!
This was a great thing to watch. Especially how huge chunks of data is being transmitted through out the entire world. Things can have so much of uses!!
Yes yes
And this gets me asking myself how much are yet to be discovered
And how many inventions more are yet to be made and how many has been made without our knowledge ( talking about UFO’s😂)
@@chidiobi9893 actually. The world is changing, we don’t know where we are heading…
I worked for a company that designed and produced "splice sleeves" for the fiber optics used in these cables. The splicing process was interesting. We had to program offsets for certain cables to allow for specific amounts of light to pass through the splice. Beyond that info I am not brainy enough to know why or how it effects the data being "yeeted" long distances. Cool stuff!
As long as the light is continuous along the cable, it will not affect the data rate. All data is encoded in binary "1's and 0's" along the cable.
@@newhampshirelifestyle4233 Hi, Fibre splicer here. using light is a bit different because any interference in the cable (poor splice for example) will affect the wavelength of the transmission. since the transmitter uses multiplexing it is that much harder to calibrate. the equipment on either end then does the 0 and 1 thing. a difference of only a few db will not work on highly sensitive equipment. the offset is to accommodate these db differences as well as the repeaters.
@@mattdadi9853 No db's = the best db's when it comes to splicing.
Ok bhai ponka
@@ryanpeschel3562 you actually want a -25 ish db for fiber it’s way different than coax
Thanks to Tech Visions and everyone who helps, works, creates, develops, and protects the world's life and technologies, I loved the concept and all that they have done for good works... The WI FI Network and LI FI Network without wires cable are the only solutions to solve the cable issue at the oceans and I don't know... You rock men and keep up the good work...
I was hoping you'd mention the Snowden revelations! Excellent video.
I actually enjoy finding cut cables in the ocean. Extremely peaceful knowing you’re this little human in a massive body of water.
Peaceful??? You must have been on the payout portion, not pulling in the 10,000 meters of drag line. It's a pain in the @$$ coiling all that back up into rope tanks.
@@thorwilliams7546 I'll I do is splice now lol. I started as a labor a longggggg time ago so yes I'm on the payout side called when needed which isn't as often as people think 😂
I’ve been working in telecoms for over 10 years and discovering subsea cables was by far my favourite part.
I started in telecom about 50 years ago. No such thing as fibre cables back then. Back then, the undersea cables were analog, with several voice channels. Satellites were also used. The first trans Atlantic cable, capable of carrying voice, came online in 1958, IIRC.
@@James_KnottThanks brother
I actually worked for the first company to deploy the Atlantic crossing...good video.
0:38 that would be tha Caspian Sea, the Black Sea is to the left; great video!
This actually bloooowwwss my mind. The way the most modern thing in our time works is definitely not as I imagined. I was thinking something depending on satellites. This gives me a lot more patience when my internet acts up for those 25 seconds. 😧😧
it's faster because it's through cable. If it was satellite, it'd be slower and more inconsistent
If you were using internet in the time of dial up you would be a very patient man regarding that, I still remember when 1mb was the king speed and before that when I would download a game (RO) 1GB and would take 1 week lol
Both cables and wireless (satellite) connections travel at the speed of light, but satellite is further away, thus increasing latency, that’s why it won’t ever replace cables. Unless we figure out faster-than-light-travel…
@@jerryg3652 The light in cable does not travel at the speed of light, because it is slowed down through the material of the cable. Light only travels at the speed of light in a vacuum.
Starlink ;p
Thanks for the video, I was once one of the few employees who have ever been on that job of coiling that cable
I find it amazing they laid the 1st cables in the 18th century for telegraphs I think thats when they discovered the ocean can get really deep like 2 miles deep
Tata Communications' Global Network (TGN) is the only wholly owned fiber network circling the planet. Most cables in the 20th century crossed the Atlantic Ocean, to connect the United States and Europe. However, capacity in the Pacific Ocean was much expanded starting in the 1990s.
When my father told me about those cables as a child I always wondered how they worked. Thanks for making this video.
how else would Atlantis get internet
Which cable? The first transatlantic telegraph cable was laid in 1858. Before the Civil War.
Technology have really come a long way, imagine a person from 1500s or 1400s would react seeing these technological advancements? even just a cellphone would probably mindblown them, a tiny gadget that could so much. WOW! just WOW!!
Jules Verne fantasized about Zoom conferences in 18something
15-1600's?
LOL, not mind blown. More like grab the pitchforks and torches because there's witchery about!
The middle ages were a time of immense power being held by the Church, so science was almost extinct and instead replaced by demons, devils, and all sorts of boogey-men to scare the simple folk into behaving themselves, and to quietly and happily give all their money over to the Church. Well, all that wasn't taken by the Lord of the area (depending on where you were living, of course.)
A lighter would amaze them. So would a modern mirror, anything made out of literally any non-natural material, electricity, gas appliances, hell...basically anything that started making modern life possible would throw them into a tizzy.
Show an iPhone to someone from the 1980s. Someone in the 1400s will just say it’s witchcraft, someone from the 80s will actually appreciate the technology, they had portable phones that were massive, no internet, and only a few people had them.
I love that this is the typa stuff that pops up on my FYP
Sometimes a lot of tech can just feel like "magic", as if it just works. It's cool to get a look at how and why.
Exactly when technology exceeds the limits many times we confuse it with magic

Probably the best way this subject has been presented so far. This feels like an informative video you could find in classrooms of the future.

LMFAO Thank you ! Wth was that !?
Yes, if your intention are to controll the flow of information and force everyone to pay for it. Yes I agree you would make sure it was removed it out of the free realm (The air) and put into cables. Wi-Fi is through the air through very small rabbit ear antennas. All info flows no matter how much. Unless you get toggled by the provider in an attempt to frustrate us from using it. By law they are required to release it in the air. They get around this by emitting such a weak signal through the air that its almost impossible to pick up on to the extent you would have to get within 30 cm.of where the signal is broadcast to pick it up.thats with an antenna.
If war between country vs country happen , And military enemy doing destroy cables , did all server military down ?
Thanks for the information, that was extraordinary. Best wishes. ❤❤❤

The video is very enlightening. I have a new appreciation for the things that I see and hear on the internet from now on. I wish there are many more of this kinds of videos to explain things that most people take for granted.
I agree completely! I also found this video very enlightening and have a deeper appreciation (and patience haha) for load times and things I see online :) Would be happy to see more videos like this
Sharks at the bottom of the ocean watching this video with their Wi-Fi: “tell us something new…”
The irony is that telegraph isn't too far off in terms of how it's sent and interpreted nearly. Over a wire and either on or off. But as explained too, the fiber optics are more complex than just running a wire now.
For a society that claims we can't get to the bottom of the ocean floor, we certainly have a lot of cables disproving that on video.
What a fantastic infrastructure!
Meanwhile my town is still struggling to implement high-speed internet and we have to rely on wireless data from our phones on a regular basis 😄

"yeeting data" at 5:31 got me lol really cool video though
I work and manufacture the cables, here in Sweden, working at Hexatronic in hudiksvall
the topic that I've always been fascinated of. people been talking about how 90% of the ocean aren't explored yet, then there are these massive cables all around the world
sure, there are objectively a lot of wires down there ...but how many wires would it take to cover the whole damn ocean floor? WAY more than 10x the cable we have now ... the ocean being unexplored and also the location of international cables are not mutually exclusive?
@@aduck2825 Im sure, when they survey the ocean topography for the cabling project, they've explored more than 10% of it. "90% of the ocean are unexplored" are a bit exaggerated is what I'm saying.

"yeeting" 💀💀🤣🤣
That comparison to the telegraph at the end, though, was pretty overwhelming for me.
I've already had to watch a lot of technology go from being "the next big thing" to "so obsolete the younger generation doesn't even know it existed". It's crazy to think even more drastically advanced upgrades to technology may be around the corner.
There is no doubt that one day those cables will be abandoned as totally useless and worthless.
I use to make the internal jointers that joined the cables together, they were 100% checked by an independent company before getting on the boat that layed them, no discrepancy what so ever was excepted, all very high precision stuff!
do these jointers have some sector alert chips to know which part of the cable in the ocean is damaged or do they just see it by the jointer itself where in the ocean which jointer sector is dead or how do they know?
@@BEFORETHEMHYPEBEASTS
No chip as far as i know, but we were only one manufacturer of many, all working on the jointers No idea what the others were making or what the finished product looked like. The jointers were made from many parts, we only made the very innermost components, and possibly not all of them. I did go to the checking company "Sea Talk in Lymington" on a couple of occasions to deliver our parts and the place was full of components I'd never seen before and this building was rammed with CMM checkers. I was told that some time back components from somebody got on the ship and we're not of spec, didn't fit basically. The ship had to return and no cable laying took place, the thing here is "who pays" this won't have been a cheap easy fix mistake! I believe this is why Sea Talk the checking company was set up, to make sure it never happened again.
@@BEFORETHEMHYPEBEASTS A pulse is sent down the cable and is reflected back. They can tell from the length of time it takes to get back where the break is within a few hundred meters.
I used to work in factory that produced this kind of cables of this ~diameter. We produced the most expensive ones with 3meters per hour. 1 meter weight is about 40 kg made of aluminium and about 75 made of copper.
Them under-the-waters interwebz lines be *thicc*
Wireless means there is signal spreading, interference (artificial as well as natural), etc.. So i don't think the wired transmission will be completely replaced by the wireless transmission anywhere in the near future. But maybe in the far future the difference may become so low that wired may not matter at all, since convenience is always better than a bit higher performance. In the far future where humans may live on different planets on different stars, it will definitely be wireless. But as for the internal core communication it may still be wired, because the physics laws will need to change to completely kill off the wired communication.
For anyone interested there is a PBS American Experience documentary "The Great Transatlantic Cable" that details the first telegraph cables laid across the Atlantic in the 19th century, from the failures to ultimate success. Very interesting.

2 years after, this video now made sense as we are experience inaccessible internet services due to dstruption of internet cables across the ocean
?
Fish: They are just sitting there...menacingly.
2 hypothetical questions - 1/ Are any national cables built or attempted to be built in secret to prevent other nations from interfering with communications in the event of hostilities? and 2/ Although it seems likely that something like starlink will be more prevalant ifor the future of communications is there a plan to continue to build in reduncies for physical cables in case something happens outside our atmosphere that would impact satallites?
Not to worry!! TRUMP enacted his SPACE FORCE,!!!! What is it and what does it do??? Dozens of tRUMP supporters were asked those questions and SURPRISE,!! Nobody knew what the SPACE FORCE IS,!! LET'S GO BANNON,!!
@@steelman86 Trump not in office btw
Well when you put a cable under the ocean to another (foreign) country it's not a national cable... So what they do at the other end is beyond your control... as well as if they tell anyone about it.
Besides, pretty sure a sub can detect a cable at the bottom of the sea pushing thousands of volts through it... all they need to do is sweep the coastline... right?
@@steelman86 This is one of the dumbest comments I've read all year and we're near the end of the year.
@@manofsteel8728 Yes, Orange-faced pussygrabber was impeached and removed, as promised.
I´ve been looking for this for a long time and am glad I found it! It´s truly amazing and I didn´t know that amount of cable was under the oceans. I thought we had a satellite infrastructure. It looks dangerous... cables need to be very strong and protected to resist such depth and conditions. Plus how are they going to be replaced after decades and the ever-improving capacity and speed of the Internet? That´s a lot of work.
i agree! Human is genius creator!
@pyropulse nobody is born with knowledge; we all need to learn it somewhere.
simply asking a question is not being ignorant, it's being curious.
@pyropulse when you think you know everything is when you actually know nothing. Dont be aa dick. The guy could know about something you know nothing about. everyone has their interests.
You said you thought we had a satellite system... that's what they want us to think... anything to further support space... we don't have thousands upon thousands of satellites floating in earths orbit... because their is no orbit.. satellites hang from balloons as large as football stadiums and the earth is not a sphere... its flat... they've been lying to you... and if you notice.. they keep using cell towers to further push the satellite narrative... because.. it makes you think we have a satellite system in place for the purpose of our phones, internet and such.. but we haven't been given the truth on what they are used for..
at last all my questions answered, thank you - fascinating - even Smithsonian which has a example of repeater did not do it as good.
