To add at least one on-topic comment here:

the team achieved 51.3Tb/s transmission over a single 206.5-km unrepeatered span using only erbium-doped fiber amplifier (EDFA) amplification

This is impressive! Our usual spans go to maybe 120 km at most if I use our strongest EDFAs. With those we can deal with around 30 dB of span loss, and most fibers we can rent have around 0.25 dB/km loss. Of course this is on classical single core fiber, we don't use HCF yet.

I remember YOFC was also at last year's ECOC, where they presented their support tube hollow core fiber concept, reaching 0.05 dB/km at some wavelengths. Here's some slides I photographed.

This isn’t for you or me. It’s for their AIs to link globally.

Why, so Zuck can stream back 8k footage of my bootyhole every time I take a shit?!

Right now I'm happy if I'm getting my advertised gig up and down. Any extra bandwidth would just be used by advertisers/spies to exfiltrate more data about me

Oh boy, this is going to really take me to the next level in Balatro

[–] iamthetot@piefed.ca 4 points 15 hours ago (2 children)

Why would internet speed affect your play of Balatro?

For the same reason switching to fiber helped me shatter my Minesweeper top score

I've stopped caring what the capacity is. Youtube doesn't require a fraction of what we have already in place.

However, they've put so many ads that an adblock is required.

But, if you have adblock you need to click the video you need to watch, let it not load, refresh the screen, wait way longer than should be needed, and then watch the video while getting a nagging popup that says "Experiencing interuptions?"

Followed by watching the video rendering NOT rendering at various points, and you need to pause and let it buffer.

All because google thinks they are entitled to push malicious ads onto my device, and punishing me for blocking them.

The speed we have is more than enough for the internet we have. The bottleneck is the companies enshittifying their own service.

Faster speeds mean nothing when you artificially throttle them.

I can see you don't regularly have to upload terabytes of data every day. A faster connection would literally change my work life.

Strange, YouTube works fine for me with adblocker.

FreeTube for your PC and PipePipe if you have an Android phone will solve all your problems

You could, you know, just not use YouTube. Like, no one is forcing you to.

[–] Axolotl_cpp@feddit.it 1 points 10 hours ago (1 children)

Kinda forced when 99% of the world that uses internet is on that platform yk

[–] iamthetot@piefed.ca -1 points 7 hours ago

I mean, it's not though.

[–] boonhet@sopuli.xyz -3 points 20 hours ago

Look, I'm no fan of ads, but... It's a free service that costs an ungodly amount of money to run. They've gotta make money somehow.

Of course the whole running it at a loss for a decade thing means they had to go the enshittification route. Could've had more ads and a subscription option long ago but they wanted to lull us into a false sense of security first :/

[–] 33550336@lemmy.world 2 points 10 hours ago

oh yes, more slop per second

[–] hperrin@lemmy.ca 72 points 22 hours ago (1 children)

I could download SO MANY LINUX ISOS!!

[–] Blaster_M@lemmy.world 15 points 18 hours ago

Or one Call of Duty

[–] Madzielle@lemmy.dbzer0.com 2 points 11 hours ago

Used to make cable filler for a living. A lot of what I made ened up in lines for google and under the ocean. It's a dirty business. We're gonna kill the planet for all this.

Damn, and I thought a station wagon full of tapes had a lot of bandwidth.

In b4.
Now that does it! I've simply had enough of China stealing our technology.
They've been doing it for decades, but now they are stealing our technologies before we have them ourselves!! 😡
The worst thing is I now have to hear about how this was never invented in China anyway, and without the west 1.4 billion Chinese people could never have invented anything, because they are too stupid.
/s

EDIT PS: For some reason OP edited the headline to be WRONG.
The correct headline is:

China: Researchers transmit a whooping 51.3Tb/s through an optical fiber channel

1.2 Tb/s is per wavelength, which is normal to have multiple of. And has been tested up to 51.3Tb/s over a distance of roughly 128 miles.

Edit PS:
Yes I know China has "stolen" technology, so has all developed countries in the world.
Especially USA was built on technologies "stolen" from Europe. So give it a rest already.

[–] UnderpantsWeevil@lemmy.world 14 points 22 hours ago (2 children)

now they are stealing our technologies before we have them ourselves!!

I remember when "Chinese students can't come up with anything new because they're too indoctrinated by Communist authoritarianism" was a thing normal people genuinely believed.

[–] Axolotl_cpp@feddit.it 1 points 10 hours ago (1 children)

Which is funny considering that China is very capitalist

[–] UnderpantsWeevil@lemmy.world 2 points 4 hours ago

Well, sure, except for the enormous bits where it isn't.

But that's mixed economies for you. They're simultaneously too capitalist and not capitalist enough, depending on who is angry at them.

[–] Buffalox@lemmy.world 4 points 22 hours ago* (last edited 22 hours ago) (2 children)

Yes I've seen something in that line of thinking as well. But even if China has schools that are not top notch, they have sent students to other countries to learn for about 50 years. And their own top schools are among the best in the world now.

#11 in Hong Kong and #13 in Peking.
IDK if the list is entirely fair, I imagine having a good and long track record could have an influence.
China has been investing heavily in research and education, several times more than what we do in Europe and USA.
So it's no wonder they are catching up, and even passing us now.

Funny to see how we both got a downvote? 😋🤣
Maybe someone still believing in the superiority of the west, which clearly we don't have a monopoly on anymore, China has caught up, exactly as Japan and Korea have done before China.

I genuinely is curious to see the exact same propaganda rolled out against China that Americans deployed against the other Eastern Rim industrial states. India is, similarly, getting a ton of this treatment.

The big difference between China and India/Japan/Korea is the failure of the Chinese government to placidly ingest western neoliberal economic policy and stagnate their economies for a decade as a result.

[–] Buffalox@lemmy.world 1 points 11 hours ago* (last edited 7 hours ago) (1 children)

Absolutely, China being communist makes them the enemy.
But to be fair, capitalism is also a declared enemy to communist countries.
Both are equally wrong.

[–] UnderpantsWeevil@lemmy.world 1 points 4 hours ago

capitalism is also a declared enemy to communist countries

Colonialism tends to be the explicit professed enemy. Communism, as a practical economic policy, revolves around securing domestic resources for the benefit of the local public. China's managed this phenomenally.

What Chinese policymakers object to is extraction of Chinese surplus at a loss. And foreign capitalists hate this, because it cuts into their profits.

[–] acosmichippo@lemmy.world 5 points 20 hours ago (1 children)

you were probably downvoted because it's completely unnecessary and off topic. no one was going to bring this up but you.

[–] Buffalox@lemmy.world 1 points 11 hours ago

OK admittedly it's not really relevant, it was merely a joke.
But you can't honestly claim to not have seen those moronic posts about how China never invents anything and only steal their technologies from the west.
They are so common it's insanely tiresome. In this thread there are none, maybe because in this case China obviously developed and invented it themselves.
