This is a most excellent place for technology news and articles.

Aren't fiber lines typically symmetrical? At least that's how I've usually seen them advertised.
You underestimate the fuckery that ISPs will go through to offer the least amount of services for the most possible money.
Don’t be silly son, the free market will signal there is opportunity and prices will drop and quality will go up.
🤪
All fed to you on the not updated data line that caps at 800 MBps
Broadband is not a speed.
Do you know how fast you were going?
Faster than broadband...
Faster than "[...] the bandwidth of a station wagon full of tapes hurtling down the highway"?
(Quoted: Tanenbaum, 1981)
Distances though? I've seen similar breakthroughs in the past but it was only good for networking within the same room.
It's optical fiber so it's good for miles. Unlikely to be at home for decades but telcos will use it for connecting networks.
Optical fiber is already 100 gigabit so the article comparing it to your home connection is stupid.
So the scientist improved current fiber speed by 10x, not 1.2 million X.
Note they did not say 1.2 million times faster than fiber. Instead they compared it to the broadband definition; an obvious choice of clickbait terminology.
It’s optical fiber so it’s good for miles.
OM1 through OM4 have full rate distances of less than 800 meters.
Yes there is faster stuff that goes for literal miles but saying that optical fiber can always go miles is incorrect.
To be fair it's obviously meant that they're talking about singlemode and not multimode.
No one said “always”; original comment is correct that fiber can literally go miles
It’s much more than just 100Gb/s.
A single fiber can carry over 90 channels of 400G each. The public is mislead by articles like this. It’s like saying that scientists have figured out how to deliver the power of the sun, but that technology would be reserved for the power company’s generation facilities, not your house.
Its not stupid at all. "Broadband" speed is a term that laypeople across the country can at least conceptualize. Articles like this aren't necessarily written exclusively for industry folks. If the population can't relate to the information well, how can they hope to pressure telcos for better services?
So it's fine if an article says Space X develops a new rocket that travels 100x faster than a car?
Because that implies a breakthrough when it's actually not significantly faster than other rockets: it's the speed needed to reach the ISS.
10X faster than existing fiber would be accurate reporting. Especially given that there are labs that have transmitted at peta bit speeds over optical already. So terabit isn't significant, only his method.
Cool I'll be able to download CoD in just a few hours.
With data caps, you can now go over your limit 1.2 billion times faster!
It's compared to the average broaband speed in the UK, so it's not quite as exciting as it might sound ...
So it’s barely faster than my phones internet when I’m traveling through nature.

One originally linked is re-post of re-post.
I remember the early 90's when fiber connection was being developed in research centers.
Researchers had found a way to transmit all of a country's phone calls' bandwidth through a simple fiber cable. Then, they wondered: what could we use this for?
This was a few years before the explosion of the internet...
With further refinement and scaling, internet providers could ramp up standard speeds without overhauling current fiber optic infrastructures.
Don't worry. They'll find some way to use this to justify massive rate increases.
We must make ISPs a public service owned by the people. Who can argue that internet isn't essential to being a regular member of society? These companies rob us and use their monopolies to manipulate us.
Wow! That site sucks on mobile.
PopSci in general has seen better days. I tried subscribing again to their physical magazines and it's just a mess... There were more full page cigarette ads than interesting articles.
remember kids, commit arson against your local ISP, and you will only be arrested for probably 20 years.
First of all some corrections:
By constructing a device called an optical processor, however, researchers could access the never-before-used E- and S-bands.
It's called an amplifier not processor, the Aston University page has it correct. And at least the S-band has seen plenty of use in ordinary CWDM systems, just not amplified. We have at least 20 operational S-band links at 1470 and 1490 nm in our backbone right now. The E-band maybe less so, because the optical absorption peak of water in conventional fiber sits somewhere in the middle of it. You could use it with low water peak fiber, but for most people it hasn't been attractive trying to rent spans of only the correct type of fiber.
the E-band, which sits adjacent to the C-band in the electromagnetic spectrum
No, it does not, the S-band is between them. It goes O-band, E-band, S-band, C-band, L-band, for "original" and "extended" on the left side, and "conventional", flanked by "short" and "long" on the right side.
Now to the actual meat: This is a cool material science achievement. However in my professional opinion this is not going to matter much for conventional terrestrial data networks. We already have the option of adding more spectrum to current C-band deployments in our networks, by using filters and additional L-band amplifiers. But I am not aware of any network around ours (AS559) that actually did so. Because fundamentally the question is this:
Which is cheaper:
Currently, for us, there is enough spectrum still open in the C-band. And our hardware supplier is only just starting to introduce some L-band equipment. I'm currently leaning towards renting another pair being cheaper if we ever get there, but that really depends on where the big buying volume of the market will move.
Now let's say people do end up extending to the L-band. Even then I'm not so sure that extending into the E- and S- bands as the next further step is going to be even equally attractive, for the simple reason that attenuation is much lower at the C-band and L-band wavelengths.
Maybe for subsea cables the economics shake out differently, but the way I understand their primary engineering constraint is getting enough power for amplifiers to the middle of the ocean, so maybe more amps, and higher attenuation, is not their favourite thing to develop towards either. This is hearsay though, I am not very familiar with their world.
Faster or more bandwith?
More bandwidth. The physical Bit already travels at the speed of light inside the cables
My docter said i needed more fiber.
