Kühe sind tollResearchers unlock fiber optic connection 1.2 million times faster than broadband
jordanlundDistances though? I’ve seen similar breakthroughs in the past but it was only good for networking within the same room.
Blue_MorphoIt’s optical fiber so it’s good for miles. Unlikely to be at home for decades but telcos will use it for connecting networks.
I wonder what non-telco applications will use this
I wonder if something like a sport stadium has video requirements that would get close with HFR 8K video?
Disaggregated compute might be able to leverage this in the data center. I could use this to get my server, gaming PC and home theater to share memory bandwidth on top of storage, heck maybe some direct memory access between distributed accelerators.
Gotta eat those PCI lanes somehow
Disaggregated compute might be able to leverage this in the data center.
I don’t think people would fuck with amplifiers in a DC environment. Just using more fiber would be so much cheaper and easier to maintain. At least I haven’t heard of any current Datacenters even using conventional DWDM in the C-band.
At best Google was using Bidir Optics, which I suppose is a minimal form of wavelength division multiplexing.
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.
BuelldozerIt’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 mile 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
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.
KairuByteThose are two completely unrelated things.
Then give me a related analogy you would accept and I’ll easily twist it into a misleading comparison exactly the article did.
How about this, “British Telecom develops high speed internet 1700x faster than previous Internet service technology. Availability is today!”
The above statement is completely true.
Comparing to home Internet when it isn’t home Internet technology is misleading. Ignoring that there are already faster optical Internet speeds in other labs around the world is misleading.
“A bus on average can hold ten times as many passengers as private vehicles.”
Except that isn’t the case here. It’s completely different technology that transfers the data. So it’s comparing a train to a car.
The vast majority of consumers don’t understand the technology being used at any point in worldwide infrastructure, many times including the tech in their own home.
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.
over 90 channels of 400G each
You mean with 50 GHz channels in the C-band? That would put you at something like 42 Gbaud/s with DP-QAM64 modulation, it probably works but your reach is going to be pretty shitty because your OSNR requirements will be high, so you can’t amplify often. I would think that 58 channels at 75 GHz or even 44 channels at 100 GHz are the more likely deployment scenarios.
On the other hand we aren’t struggling for spectrum yet, so I haven’t really had to make that call yet.
Eager Eaglexfinity will advertise 100 Tbps lines with the abysmal 1.5 TB/mo data cap anyway
“you can drive this super sport car for $ per month - but only for 10 miles”
100Tbps downloads speeds (5Mbps upload)
Speeds not guaranteed…
Isn't the phrase they use "up to" the promised speed? So if it is 300bps, that is not above 5Mbps, so they technically met their promise.
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.
Mine at least lets me adjust the upload and download ratio for my plan. I’m currently on 50/20, but I could upgrade my plan and get 100/20, 70/50, or whatever I want. But 50/20 has been plenty for me, and we’re getting municipal fiber soon so I’ll have more options as well.
AFAIK, cable doesn’t offer that, you get 5mbps on pretty much every plan, or you upgrade to some ridiculous tier to get faster upload.
5Mbps is absolutely bonkers. I had 30/5 back in like 2006. And TCP has an overhead of about 5%, some protocols ever more.
I had gigabit a long time ago, and while it was nice, I’m unwilling to pay for it. 50/25 is good enough for me, and it costs less than half what gigabit would cost ($55/month vs $125/month). I just checked, and apparently all plans have half the upload vs download, so that’s nice.
Our new service promises to be $60-70 for 250 symmetric, and that would only get me 100/50 at my current ISP, so I’ll probably be getting that upgrade when it’s available.
I hate Comcast as much as the next guy but I feel like 1.5TB a month would be reasonable. Even at those speeds you probably wouldn’t be downloading more, just downloading whatever you do now but faster.
SneezycatWhy the fuck would I want that speed if I can only fully use it for less than a second before hitting the data cap? I’d rather have 100 times less speed with 100 times more cap, so I can actually fully use it however I want.
Also it’s just ridiculous anyway because I don’t even think hard drive write speeds are that fast.
I think you meant no data cap.
Tell that to my (nonexistent) off-site backup.
Florida man fails math, yet sgain
I’m not even from Florida 😭😭
Planning on a namechange for my Internet personality soon though
There shouldn’t be any data caps on wired connections, especially fiber.
The only thing data caps should affect is if there’s abnormal congestion.
RonSijmThe should be, that’s just how fiber works. If they lay a 10 Gb line in the street, they’ll probably sell a 1 Gb connection to a 100 households. (Margins depend per provider and location)
If they give you an uncapped connection to the entire wire, you’ll DoS the rest of the neighborhood
That’s why people are complaining “I bought 1Gb internet, but I’m only getting 100Mb!” - They oversold bandwidth in a busy area. 1Gb would probably be the max speed if everyone else was idle. If they gave everyone uncapped connections the problem would get even worse
ArtVandelayMaybe, just maybe… Don’t oversell your capacity.
You’re taking about data rates here, measured in bits per second.
Data caps have to do with the total amount of data you are allocated over a longer period of time. Usually per month. In the case of Comcast, it’s 1.5 TB/month.
If the customer exceeds that allotment during the month, they will be charged an additional “overage fee” per arbitrary unit, usually by the gigabyte.
It has nothing to do with the speed they advertise on a line, but rather a way to charge “heavy users” more.
you’re talking about a bandwidth cap, not a data cap. data caps are when you get throttled after downloading a certain amount of data or get charged extra. think phone data plans where you have 10 or 20gb or whatever per month
I’m on pace for 0.60 TB this month and I’m no heavy user. I only have 1 4k TV and a laptop for work that I use all day. My wife is mostly on her phone but is a heavy TV user in the evening. I can imagine people who download and/or torrent most of the content they consume can easily hit that.
Data caps are simply false advertising - if your infrastructure can only handle X Tb/s then sell lower client speeds or implement some clever QoS.
There are plenty of users for whom 1.5TB is quite or very restrictive - multi member households, video/photo editors working with raw data, scientists working with raw data, flatpak users with Nvidia GPU or people that selfhost their data or do frequent backups etc.
With the popularity of WFH and our dependence on online services the internet is virtually as vital as water or electricity, and you wouldn’t want to be restricted to having no electricity until the end of the month just because you used the angle grinder for a few afternoons.
doublejay1999Don’t be silly son, the free market will signal there is opportunity and prices will drop and quality will go up.
woodenskewerAll fed to you on the not updated data line that caps at 800 MBps
DasnapCool I’ll be able to download CoD in just a few hours.
Faster or more bandwith?
More bandwidth. The physical Bit already travels at the speed of light inside the cables
The transiever and network processing stack at some latency as well.
With data caps, you can now go over your limit 1.2 billion times faster!
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)
There are limitations to the technology, similar to saying 3 times faster than sound.
Also broadband as a regulated term would have speeds tied to that definition.
according to the FTC or FCC whichever one it was recently raised the defined speed of a broadband connection.
It’s not symmetrical yet though. Which is weird.
It’s not symmetrical yet though. Which is weird.
Eh, I would say it’s to be expected. A lot of infrastructure still relies on coax/DOCSIS which has its limitations in comparison to an all-fiber backbone. (This post has some good explanations.) However it wouldn’t surprise me if some ISPs argue that “nobody needs that much uplink” and “it helps restrict piracy” when really it’s just them holding out against performing upgrades.
Why does a gigabit/sec Internet connection via cable (coax) not offer symmetrical speeds like fiber?
In our area, we have Cox Communications (cable) which offers 1 Gbit/s down, and 30 Mbit/s up, while CenturyLink (fiber) offers 1 Gbit/s up and down. Why does copper only 'allow' fast speeds for
it really shouldnt be though, this is going to be in effect for like, the next decade or two. FTTH is literally fresh off the presses for most suburbanites, and city dwellers, i see no reason that this standard should be so antiquated anymore.
Literally only incentivizes ISPs to keep rolling out shitty infra that’s slow as balls everywhere that isn’t suburbia.
Wow! That site sucks on mobile.
Dark ArcPopSci 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.
