Its a shame i dont have an ethernet cable that fast or a motherboard with a network interface capable of that speed.
Great if i can get faster fibre into my home but my internal infrastructure is not up to the task. This wont be in the home until we can use fibre cables like we currently use ethernet cables.
Or is there some other tech that would replace ethernet that would handle those speeds. Also whats my wrote speed on my ssd?
Yeah i dont know if thisnis a tech thats meant for home, more likely large businesses with lots of devices all fighting for bandwidth.
The closest that comes to mind are QSFP cables.
Broadband is not a speed.
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.

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.
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.
Faster or more bandwith?
More bandwidth. The physical Bit already travels at the speed of light inside the cables
I’m highly suspicious about group dispersion over long distances. Today’s infrastructure was developed for a certain range of frequencies. Broading it right away wouldn’t be applicable that easy - we would need to introduce error correction which compromises the speed multiplier.
Too lazy to get the original paper though
We already have transceivers that perform forward error correction. That technology is a decade+ old.
Dispersion compensation and FEC are separate layers of the cake, and work hand in hand.
The zero dispersion wavelength of G.652.D fiber is between 1302 nm and 1322 nm, in the O-band.
Dispersion pretty much linearly increases as you move away from its zero dispersion wavelength.
Typical current DWDM systems operate in the range of 1528.38 nm to 1563.86 nm, in the C-band.
Group dispersion in the E-band and S-band is lower than at current DWDM wavelengths, because these bands sit between the O-band and the C-band.
xfinity 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”
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.
E: I was gonna ask why this was so controversial but I just checked my routers stats and, oh yeah I’ve only downloaded around half a terabyte over 3 segregated VLANs in the past 2 months. I’ve uploaded almost double that which is baffling to me though. Even still I don’t see why anyone would be downloading anything more that a terabyte in a month unless your one of those data hoarders, which fair but… I’ll stop my rambling.
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 1.5TB
Why 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.
There 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
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.
Don’t be silly son, the free market will signal there is opportunity and prices will drop and quality will go up.
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.
