I used to work for a bank, but then I lost interest.

why would you cut it in half when you already have two ends that are cut??

The cable is already cut from the sides?? 😂🖖

probably could of just taken the tape off of one end... lol

Are these guys the reason my internet is being so bad?

I just found this channel, I have worked for Internet service providers since 1998, the Internet hasn't used satellites in a long time because of the latency (the light speed time delay of transmitting a signal up to the satellite and back down to its destination). The hardest part about fiber optic connections is signal loss, so the cables you cut open are connected, at intervals, to repeaters that are also waterproof and designed to work at the bottom of the ocean. The fibers themselves don't really need to be upgraded that often for an increase in speed, it's these repeaters and the endpoints that need to be upgraded to increase the speed of a run. Food for thought.

i like how they taped the ends of the wire to not reveal what's inside as it would defeat the purpose of cutting it open and wasting our time. Nice one lads.

Do "What's inside our ad revenue" next time

Be grateful for slow internet? If it were free sure. Not when i'm spending $120 bucks a month.

its already cut at the both end ??? why still cut at the middle ????

Why are you cutting a cable that's already been cut?

Isn't the cable already cut in cross-section at the ends though...?

Couldn't you just have looked at the end ? I know this is what's inside but I'm just wandering was the saw necessary ?

It really is fascinating how you can upload a video and have two people watch it at once. Technology is great! You should try this video thing sometime. :P

"It's kinda like when you hold a meteorite" Yeah... because that's something everyone can relate to.

6min video for 45 seconds of actual content....

The thumbnail tells us what's inside-_-

what's inside an oversea internet cable

2:58 "Which tells me there is going to be some heavy metal in here." Heavy metal? HEAVY METAL!?!?

You know, as a telecommunications engineering drafter for the past 6 years designing routes for fiber optic cable throughout the Midwest (based in Chicago) I only just recently learned that there are fiber optic cables spanning across the freaking oceans to allow us to communicate with one another cross-continentally.

5:20 yeah what do u mean....thats why we pay for internet...

Can You Cut Open A Mood Ring?

My son is a merchant mariner who works on a cable laying skip. He is an engineer responsible for feeding the cable to lay on it under bottom of the ocean (depending upon the sea depth) at the right tension to avoid injuring workers or breaking/tangling the cable. That's over Simplified but the job requires a 4 year engineering degree and a USCG license he must keep current. It's a very high tech process sand a very unique job. He is out to sea across many continents all the over the world anywhere from 75 days to over 4 months at a time. A very cool job!

They didn’t go all the way in. The colored parts are protective layers around the glass inside and then there are at least two layers of glass. The light is only in a 10 micron core in the middle.

So cool!

Last task in my *''Being a Jerk of 2016''* bucket list.... Cut down Internet cable to Russia and blame USA. Reward See World War 3 and enjoy popcorn

“What if a shark came and bit it” he literally predicted future

All of those protections just so that people could argue online with strangers and spamming Harambe

Couldn't you just take the tape off the end?

"be grateful for the internet" but i pay $110 for landline and 1TB of internet!

Amazing to watch people try to understand physical things working men deal with every day.

I like how at the beginning Lincoln is just like "and this is dad" lol

What's inside an amazon echo dot????

I thought Dan was wearing a onesie for a few seconds.

The astonishing thing is that they have been laying undersea cables for 150 years. The first cables were for telegraph and were laid in the 1850s.

Wow!! Thank you so much for sharing this!! All this time Ive been wondering how this was made..

It's crazy how we're all connected by one cable!

I'm amazed that those cables are thinner than an Ethernet cable, yet they can carry an entire country's worth of data. I thought they'd be more like the cables you see at power plants and such, several feet in diameter plus the protection. Like a sewer line or something. Amazing. How many cables are there running between the different countries of the world?

"kind of reminds me of when you hold a meteorite" that's so relatable!

They are called fiber optic cables they use flexible glass rods that are insulated so light travels through it untouched we control that light and transform it into data

4:32 if you could see it clearly from the other side, why bother cutting it in half?

i did'n't know that Mark Hoppus is a youtuber now.

Hey guys I think you guys forgot to follow the right instructions about hazards surrounding Optical Fibber Cable ! I hope this help 1. Wear safety glasses - Every person in the area must wear safety glasses with side shields to prevent fiber shards and splinters from entering the eyes. People, who wear glasses, must still wear safety glasses. 2. Wear protective aprons - All workers should be clothed in disposable lab aprons to reduce the fiber particles that collect on personal clothing. If particles collect on clothing, they will be ingested later through food, drink or breathing in air. 3. Avoid fiber ends - There are reasons to look through a fiber cable, but care must be exercised to ensure that there is visible light coming through the cable. Prior to looking into the end of a cable, use an optical tracer or continuity checker to determine if the fiber is dark. A power meter will verify that there is no light source at the other end of the cable.

I like the fact that they cover the ends of this cable with duct tape, and then cut the thing in half with this underpowered saw. Seems legit xD

What's in what's inside!!?!

Man these KZfaq adventures are fun!! Here is the Behind the Scenes Video: kzfaq.info/get/bejne/mNSedcmhlbKZo58.html

What's inside the Great Wall of china

The video he's talking about at 5:21, is an interview on Conan o'brien show with Louis C.K called "Everything is awesome and nobody's happy" which i urge people to go watch.

Super cool! Now I wanna see how they actually lay these cables all the way to Brazil! Can you do a video on that? 😉

I wouldn't make-do with an abrasive blade on a chop saw intended for wood cutting if I were either of you. :-( Use a proper tool (e.g. sawzall for instance)

Nodding your head when someone is telling you information is universal

I guess everytime i play csgo a giant shark bites the cable.

Super interesting! Always wondered about those underwater cables. Great that KZfaq gave you a place to cut them too! -John

"I had this thought the other day, like where does the internet come from." I swear to god they are like cavemen that are just starting to question existence. Did he not go to school or is he just dumbing things down for a younger audience?

HAHA 4k in Australia, i didnt know this was a comedy channel XD

Packed away somewhere I have a foot of a tether from MBARI (Monterrey Bay Aquarium Research Institute) which they used to connect their remotely piloted submersible vehicles with the command ship on the surface. It has a bright yellow jacket, with 5 electrical conductors to feed 3-phase power down to the submersible vehicle, and in the core 8 optical fibers. Two were used for ethernet, two for video from the cameras, and there were some dedicated to the control system which piloted the vehicle. The cable was custom made for MBARI by BIW (Boston Insulated Wire). The cable was wound on a large, motorized drum on the deck of the command ship. To maintain connection while the drum rotated, in its center were 5 slip rings for the electrical conductors, and 8 rotating optical joints for the fibers. The was a short piece of cable coming out of the center of the drum on the other side of the rotating couplers which went to the control room below deck. They could not put any twists in the cable as they reeled it in, like the kinks which inevitably seemed to get in old-style telephone handset cords. They had a computer which kept track of how many times the the cable had been twisted by the motion of the submersible and the ship, and they had to sail the submersible and/or the ship in circles as the cable was reeled in to be sure there were no twists!

I had no clue these were even a thing. This was way cool. Thanks for sharing!

This channel grew so fast man damn

I believe the comedy bit was Louis CK and having the first in flight WiFi ever stop working. To paraphrase “This Internet sucks!” “Lady you’ve had it for 5 minutes! We JUST got this!”

Great episode! I manufacture medium voltage cable. My job is to install the jacket compound by use of an extruder. I've jacketed cable that is almost 5' in diameter. There is a lot of work that goes into making cable. While cable is not that exciting, it is sort of fun to see what's inside of it if you are not already familiar with it. The big cable I have made is three conductor, full of fillers and fun stuff with a thick jacket on it so that alligators and other critters cannot bite through it.

This is so cool like every video is cool am I right

So, what happens if someone finds it and cuts it?

at 5:19 lincoln discovered the true meaning of life

Blows my mind that people don't know this stuff. I researched this when i was 9 out of curiosity

What's inside a ouijia board

video starts from 3.50 thank me later

The company I work for pioneered the subsea cable burial market with the development of the subsea plough. We design and build vehicles that bury power and telecoms cables as well as subsea pipelines. There's some brilliant maps online showing cable routes across the globe.

I’m not entirely sure but today, fiber optic cables are used which use light instead of electricity. This makes it almost instantaneous for data to travel.

WOW ITS BEEN SO LONG WHERE WERE YOU GUYS

this little boy is corny but I am not gonna slay

OK 1 Judging by gauge of those wires, we speak about Very High Voltage in areas of tens of thousands Volts 2 I am pretty sure lady made quite significant error! SFPs are NEVER rated in miles, but ALWAYS rated in metres and km. To support my own claim I would add that 400m rated SFP uses 850nm light, 10km and 40km rated SFP uses 1310nm light, 80km and 160km SFPs are using 1550nm light. I know we can generate longer waves, the limitation is size and laser used in SFPs - SFPs are quite small and they are smaller then most USB Pendrives. I do think those repeaters are 40 miles apart, as this would enforce usage of 80km SFPs and would waste 15km of usable range.

KZfaqr: there's gonna be some heavy metal in here. * cuts open cable, rock and roll starts to play*

What if you put that cable in your pc?

The ends are taped over so that you cant see whats inside

What an amazing video and thank you....even years after 1st airing. I'm 75 and had no clue!

Next Video: Whats inside a Google Data Server? or Whats inside Googles website.

@5:30 I think that was Louis CK skit you were talking about.

What? Repeaters? Minecraft?

The first Transatlantic telegraph line was completed in 1858. Tiffany & Co purchased all the remaining cable from the ship that had laid it, and cut it into pieces. Some were actually made into jewelry, but most of it was not sold when the cable failed a few months later! The cross section of that cable is pretty similar to this one.

25 years ago my dad accidently cut a fiber optic cable whilst working at the the railroad, surprisingly, the company lost about 1.2 million dollars every second the cable had been cut.

my internet connection is becoming slow , is it because of a shark biting these undersea cables ?

awesome Video thanks again :) I hope u guys can come to New England someday i am from Vermont

The wire was already cut at the end and he cut it in the middle 👏

Excellent! so refreshing to have the kids involved too! go you. Smart

So the copper is there to carry power to those amplifiers?

So if I go on a ship, will I get fast internet?

Lo has the warmest smile I couldn't help but smile with her

when he said someone in Australia could watch a video in 4k i lost it... Maybe about 2-3% of the population

the under sea cable that connects indonesia to the internet is broken im not sure about this but i heard that from an indonesian news website

Why would u think it would be satellite, it would get interfered with so much and be slow, so cables only would be fast

Through those slender cables runs 98% of all modern telecommunications. And they have improved over time: in the age of electric telegraphy and morse code, it would have taken 74 days to send a Harry Potter book (unless it was 'Goblet of Fire' or 'Order of the Phoenix' - those would have taken A LOT longer), but using today's fibre optics, a Harry Potter book takes 0.000006 seconds.

One whole continent internet usage might pass by those tiny little cables at any second. Mind blowing.

Seriously doubt that's an undersea cable. Undersea cables are bigger than that and they are more flexible.

Your channel is the best channel because you cut things we wonder about. I can see your future in KZfaq. Thanks for the video

Content gets so much better everyday 100%

Whoa it’s a lot thinner than I thought, and just 5 tiny hair sized optical wires transmits information with a bandwidth for an entire country is insane just thinking about it how it’s even enough 🤯

I want a chager cord that long

Wow I never new that I always thougt it was satelite !!!

That cable essentially is a beefed up coaxial cable. Although it's not as thick as I expected
