I am not sure if this is a glitch on YouTube or it was meant to be although this video is posted as unlisted and does not appear under the "videos" section of the LinusTechTips channel page.

They often make the video public shortly after linking it here - It'll take a couple minutes for them to flip the switch.

For those wondering, the technology is called DWDM (Dense Wave Division Multiplexing) and is part of what's used for GPON and a lot of other fiber based installs to split the signal between homes and also transmit internet and TV over the same fiber. Unlike GPON and other fiber installs that use a single fiber, this uses a pair of fibers instead all the way to the node.

XGPON (the latest GPON revision iirc) is only capable of about 10Gbps down and 2.5Gbps up right now.

 

Edit:

To clarify, this is a simplified explanation, as mentioned below.

Why though

Bragging rights, marketing, and to demo some technological advances.

Good job Linus for this amazing information about servers and internet

[Nivius]

so Comhem can deliver uber fibre to comhem, but not fibre home to me

[GDRRiley]

nice bit of black magic gear there for the live streams, I'm somewhat surprised they aren't using something like a tricaster it makes sense when they started to go custom because it is cheaper but now, I guess they just have it custom and tuned with enough support staff for it that it doesn't matter.

Finally it's released, I've been waiting for this video for awhile now

 

also it was fun to bump into to 2 of LTT randomly during the build up of Dreamhack, when I was on my way to help my fellow DH crew mates in stage production

[Lurick]

For those wondering about the equipment and parts, I think I can say what most of it was:

 

DWDM Setup:

2x Cisco NCS 2006

--2x NCS2K-400G-XP

--2x NCS2K-12-AD-CCOFS

--2x NCS2K-TNCS-K9

 

2x NCS2K-MF-1RU

--1x NCS2K-MF-UPG-4

--1x NCS2K-MF-MPO-16LC

 

Distribution Routers:

2x Juniper MX960 routers with some 10GbE and 40GbE linecards

 

Distribution Switches:

23x Cisco 3850-48T-L

-- 1x 4x10GbE Module

 

Access Switches:

Various Cisco 2950, 2960, and other misc switches

 

Other:

Various patch panels

Some Cisco 4948 switches and other random switches

Several Dell servers and some Cisco UCS boxes

Hey, just wanted to note that GPON and DWDM are very different things. GPON does use some basic WDM to combine upstream and downstream (and some times a third for CATV) wavelengths, but that is not even close to DWDM levels.

GPON (same for XGPON) are about the method of using a single fiber uplink and a series of passive optical splitters to connect multiple optical terminals.

As for the 10G PON - there also symetric 10G PON standarts, there is not sinble one standard, but a bunch and different HW venfors are betting on different ones.

Yah, I should have explained that was a simplified version of it but you are correct. I had kind of figured there would be symmetrical versions of PON but I didn't check into it so that's my bad. Thanks for the info

World's Fastest Internet - 1.6 TERABITS per Second

Is it only me or this video should have been called somehting else?  like something something "dreamhack walkthrough". Mainly because they also talk about the rest of the setup there. 

BTW I'm part of the volunteer crew for Dreamhack montreal and it's always awesome to be a part of an event on this scale

the guy is playing Starcraft 2, you can see the UI

in Starcraft 2, there is a hotkey custom layout called "The Core". it involved the player to utilized hotkeys for control groups, camera group, skills/spells to its absolute optimization. based on the hotkey layout you kind of have to tilt the keyboard as such

Nice, you should apply to Dreamhack Winter 2018  usually winter is even larger, and we actually do have people from North America join the crew in Sweden

Yeah I really want to but I lack the money to do so     I live near montreal so it's a lot easier for me ^^"

There's also Lan ETS montreal so I am able to go to two lan parties per year

It's not 8 wavelengths

Just for an FYI.

There's 2.4 TB ps possible and being deployed in USA for the long haul back bone which splits the wavelength into 96 different frequency. Each capable of carrying 100gbps 

Ciena is making these equipment. Cinema 6500. And wave server ai.

Didn't get enough screen time IMO. Those are some bad-ass routers and they pretty much still run most of the internet backbone to this day.

 

Those line cards actually support 100G too, and based on the optics, I think that's what they're operating at, plus I think I saw some QSFP48s in the DWDM gear, which makes sense, 4 cables per card, 2 cards per router, 2 routers, makes 1600Gbps. Unfortunately, I have a feeling their upstream capacity is the bottleneck here since I don't know of any ISP that sells over 100G. Still boggles the mind; I've only ever seen 100G on backbones or VERY big tech company uplinks. Also, they skipped slot 0 which hurts my soul.

Thanks for finding this out!

I know that I am literally 10 months late to this discussion, but I think that ComHem would have been using NCS 2015's because in order for it to be truly redundant and carry the 1.6 Tbps on failover, only the NCS 2015 can run that much bandwidth. I mean this all in good spirits, thank you for doing this research!

I would think they would go with the NCS 2015s but I don't think they had failover in mind as well but just pulled up the pictures and zoomed in to confirm and they are actually using NCS2006's, this picture isn't the best but you can definitely make out the two 2006 chassis on the right side. The 2015s would be much bigger.
