  • "Anthony I turned myself into a pickle! I'm Pickle Linus!"

  • And they had to censor that for a year 🤦 why couldn't he just say it's a normal cable

  • "can't transfer power" *Photonicinduction has entered the chat*

  • Linus: ~has Corning optical Thunderbolt 2 cables on his setup~ Corning: "We've got something new but we can't talk about it." Linus: "Something new from Corning that takes the place of my Thunderbolt 2 fiber that I can't talk about" Everyone with a Brain: "Hmm, guess it's just Optical Thunderbolt 3..."

  • You wanna get knotty? ;)

  • I listen to these videos instead of watching them and sometimes it sounds like you guys are having rough, yet polite, sex. Music to my ears

  • Thumbnail looking kinda sus

  • Could i get any low end or min end pc for my friend i dont have a gift for him on his birthday because hes done so much for me and i really want to give him soemthing special

  • 1:08 A dark mode friendly intro!

  • anyone know what the thunderbult dock that linus uses is, couldn't see it referenced in his home setup vidoes and just googling them is a pain

  • 12:26 Nope still can't run the data to MRI or use the cable inb the MRI room as the ends (and the machine you use the data) has magnetic metals. Yes you can make cable run thru MRI room if you can make your run shorter that way.

    • This is gonna be demonetize anyway

  • 6:39 I see the knotty knot, and I feel bad for the one who needs to untangle it later.

  • "Three VCSELs and three photodiodes" while holding a 4 fiber bundle. Thunderbolt 3 has a requirement for 4 lanes (2 up and 2 down), so unless I am missing something you guys messed up in the video. Not that it really matters, but hey.

  • 20GBit/s is nothing. Singlemode fibers can easily transmit up to 80 or 128 Channels of 100Gbit/s simultaneously on one pair (RX/TX). Also yes this is by far the easiest solution but you can always get a bunch of media converters and transmit your grandmothers TV signal from one end of your house to the other.

    • 6:15 I can't watch this😭. Poor cable. I am sorry for you...

  • Rather useless product if you don't have a thunderbolt

  • Optical Thunderbolt cables? Please. Who here remembers Light Peak? Anyone? Okay… Yes, Light Peak, which used fiber optics, was the code name for Thunderbolt before they concluded that copper wires was good enough for the signal (and, added bonus, *power*). It wouldn't surprise me if the spec still has info on how a TB optical cable should work.

  • That also must be a Gorilla Glass core 🤣

  • Knotty indeed

  • You need to always include the price in Canadian as well. Thank you.

  • This cable has swag

  • Given that it’s pride month, I thought the title “revealing my big secret” was going to be something completely different...

  • 6:36 What Laptop is that ?

  • Fun fact, everytime you had a corner in an optical cable, it slows down the speed of the signal. 50 meters of straight line is faster than 50 meters of "rolled" optical cable (because the light has to bounce on the walls of the core of the cable. It never moves in a perfect straight line inside the cable. (I learnt this in ground military equipment maintenance classes).

    • This looped fiber optic mechanism is used at stock exchange IEX to induce a 350ms latency intentionally:

  • Little did you know I can see through pixel censoring.

    • work and was well passed the return period. Sigh. Thanks you guys for all that you do!

  • can this be used to connect a MacPro (latest gen) to the Apple Pro Display? That tower creates a lot of heat, and I'm struggling to find a solution to move into another room.

  • This is gonna be demonetize anyway

  • Why not include power wiring down the same wire? Surely I'm not the only person who has thought of running power wiring down the same cable as fiber.

  • they coulkd have added a couple copper wires to transmit power. Thats super fail they didn't. Because you have to power everything separately which adds MORE WIRES!

  • 6:15 I can't watch this😭. Poor cable. I am sorry for you...

  • Could they just have made it fatter and made it for like 50 bucks? They need to rein in their engineers at Corning...

  • Fiber glass patchcords aren't actually made with glass (with an exception). This cable's core is probably made with some plastic, hence why it's so flexible

  • If i wanted a job at your company how would one apply?

  • 11:52 is that a Apple i-Lamp? 🤣

  • I love how he is explains tech like I’m literally 3 years old haha

  • Very nice product. However, I'd have expected them to run two copper wires to allow that cable to transfer power in addition to data. It's not like adding power lines to that cable could cause any interference and the cost of required copper would be neglible for the actual cost of this cable.

  • Why does a 5 meter cable cost $360 and a 50 meter cable cost $480? That makes no sense. That a 50 meter costs $120 more. At 10 times the length, wouldn't it have to cost 10 times the price ($3600)?

  • I've seen TFOCA II cables tied in knots and still working just fine. This does not surprise me.

  • Great video. I think you guys should consider making a video on solutions for longform HDMI 2.1 cables, or another solution, as myself and others have had a really hard time finding a long HDMI 2.1 cable that reliably does 4k@120hz over 30ft (9 meters) without dropping. Most of them don't even do 4k @120hz as advertised. It took me 4 tries to a 55' that worked but ideally I need a 65' and I don't want to risk another $200 on a stinker. I was even out of $150 cause of one I bought months prior to getting my 3080, which didn't work and was well passed the return period. Sigh. Thanks you guys for all that you do!

  • What dongle is that? I see a SD card reader and i need one might cop it if someone can tell me what it is

  • Actually Linus.... I bought a green led from radio shack in 2005, aimed and shot a green laser at it, and got voltage on a multi-meter attacked to the two pins of the green led whenever the laser hit it.. So theoretically you actually could potentially transfer power over that fiber optic cable at some point in time as technology progresses.

  • Ok, that is just simply unbelievably cool. Believe it or not, in 1981, I was in the Navy and we ran fiber from the "Server Room" [note: back then a 5MB drive was those multi-platter 2311 disk storage units], and the fiber was brittle and failed and was expensive and people literally lost their job for screwing up. (Let's not talk about $1,000 toilet seats). For me, this is such a cool advance. 50 meters is significant. Great find LInus. If I could do 5 thumbs up I would give it.

  • You should compare this one to apple pro tb3 cable

  • i cringed when you pulled on that cable, i thought it was dead.

  • Linus biggest Problem: A GPU dying, not a perso xD

  • So do i put a display port to lightning adapter into the gpu and plug the other end into a lightning hub that i then connect my monitors into? And what of my mouse, keyboard and audio devices?

  • Fiber optic core filaments these days aren't glass, most are a plastic polymer.

  • Why didn't they add a couple copper wires to provide voltage + and -?

  • 6:37 . . . "You're Welcome"

  • "what can we not transmit over fiber optics? power!" Wrong, there are actually fiber optic cables that transmit power too. In the form of high power lasers that get converted into electricity at the receiving device. They're not as thin though and and heat is an unavoidable issue.

  • Is the lamp in linus’ office made from the base of an old IMac?

  • how hard would it be to just put a couple copper cables down this thing to also deliver power? I don't know how useful it would be for most real-world use-cases, but at the very least, it could maybe add further strength, right? Speaking of strength, your demonstration was compelling, but I would like to see a test on fatigue from less extreme but highly repetitive bending. At this price point, you want to be DAMN sure it's gonna stand the test of time. Wrenching on it a couple times and surviving is one thing, but what if you had it running under the carpet and you had less than stable floorboards, there might be spots along the cable that are subjected to small but frequent disturbances from just walking around that could add up to big problems, and that's not to mention running it under/over/around doors etc. Anyways I'm just holding out for the wireless future, no cables ever again, even for power, anything less is a stop-gap

  • About two years late on the pickle joke

  • epic cable, praise the cable gods

  • Cable costs half as much as the PC I'm using. Guess I'm not going to be using that cable.

  • I feel for all the employees falling over that cable.

  • Lol was so distracted by the Linus Cat Tips xD

  • What could be a cool idea in the not so distant future is instead of having those Japanese gaming hotels maybe you could have a server room with either a PC to stream off of or use a dock built into your hotel room that you have to pay a certain fee to turn on

  • So the equally expensive thunderbolt 2 version of these cables overheated and failed after just a few months of use? Why on earth would anyone trust the latest revision?

  • Being from Corning, I always love seeing or reading content like this. Cheers!

  • Why not add a regular ol' wire for power supply and isolate the data transfers to fiber optics?

  • Can you do this with vr connectins like with the rift cv1

  • thumbnail is like "I showed you my thunderbolt plz respond"

  • I still don't get it. Haven't we been able to do this over fiber cable for years with thin clients?

  • The dependent japan pharmacokinetically divide because police epidemiologically fry among a ambitious fowl. joyous, sloppy gender

  • i donno y. linus sang sound pretty good lol XD

  • Linus Cat Tips? Nice.

  • Why did I think that was a mushroom

  • Just 20 Gbit/sec? What year are you in? The optical fiber itself doesn't limit the speed, only the electronics and optics on both ends are the limitation, not the glass I have 40gig optics in my leaf-spine core and my ISP uses 100Gig optics,

  • 400 dollar cable..... i feel sick

  • 4:55 That actually made me cringe so hard, it was out loud. Knowing how fragile fibre can be... The continued testing was so damn impressive.

  • ill never have use for that cable but hats off to the corning people! That's incredible!

  • I kinda want to do the pc in another room thing too...

  • remember when 2mb of ram was a thing? huh...

  • Cables overheating is normal thing due to natural resistance of condactors in the cable, that why cables comes voltage and current limits as if you cross them cable starts to heat and it can even melt isolation if you go extreme

  • 50m cable me :500 smekels, thats not that bad 5m cable Me: 400 is too much

  • Shame we never got the original idea for Thunderbolt. It was meant to be fiber, but also have a copper run for power. Maybe by Thunderbolt 6 it will fulfill the original goal. :)

  • *here have a cable no one needs, and a GPU in a box no one needs* have a Liquid cooler no one needs.... OC so you can shorten the lifespan of the components because you know.. just throw stuff in the trash. Here buy this "glass wire" like why didn't they call it that? for easy payment of the price of an average GPU you too can have GLASS WIRE!

  • Practical Use: I recently purchased a Vive Eye VR headset with WiGig Wireless, which requires that the computer be near the play area for wireless connectivity. But I also use my computer in my office across the house, and need dual monitors to work. Corning 50m cable and a thunderbolt 3 hub was the perfect solution with no performance hit. I have had no issues and love the setup, both for VR work and Office computer work flawlessly. I am blown away at this cables ability to function it does not make sense to me. This cable defies logic! Probably could have built a whole new PC for the cost though.

  • shill? chill? schill? me no spell good

  • Me: Scrimping and saving what I can to buy a new $200 SSD Linus: Let's go f*ck up 2 $400 cables

  • Nice.

  • What is the blue remote that Linus held here?

  • If Ting's outgoing call sound was "skrr aa", does that mean the ting goes skrrra pa pa?

    • @Ting Mobile Thanks for confirming. This reply made me wanna switch to your network, if only you were available in EU...

    • That is correct.

  • Hi Linus But arent you limited to 60 fps on your tb dock for 4K anyways

  • tow a car with it

  • But when is the pickle review

  • FINALLY a cable that I can use to connect my Thunderbolt dock 50 meters away from my desk in my MRI Scanner room !

  • A transceiver, then.

  • dude 3080 TI

  • My workstation doesn't have thunderbolt. How would this cable connect directly to a GPU? (3080, 3090 etc) Is there a way to adapt Display Port to Thunderbolt directly from a GPU? Perhaps a dock or the same DP to TB adapter at the monitor end?

  • whoa a tech tip

  • I think, Linus has a great voice for singing 😎🎤

  • 6:35 - So when is the LTT #MeToo announcement video coming out?

  • Why thunderbolt instead of USB ? why did they reinvent SFP+ ?

  • Wow....just wow!

  • Whenever Linus shows preview of Shadow of the Tomb Raider game in his video, he is always at the same location in game, near to the bridge.

  • A latency test would be nice.

  • Fiber is the way to go especially for speed and distance .

  • The way Linus ties that knot while it's hurts my soul just watching...but man is that cable tough.

  • It took so long thunderbolt 3 has been replaced by thunderbolt 4...
