China is quietly pushing ahead with massive 50,000Mbps broadband rollout to leapfrog rest of the world on internet speeds

This is for PON technology. 1 fibre can be split 32-ways to feed, you guessed it, 32 customers. 50g over a fibre that is split 32-ways with a minimum of 15db loss is impressive.

I guarantee those 100gbps circuits are a single fibre all the way from the provider to the customer. And they are expensive, very expensive.

[ilovethebomb@lemm.ee]

Possibly not, but if their whole company can run off 10 gigabit, who needs 50 in their house?

I didn't read that this was for residential connections?

[squizzy@lemmy.world]

Its not that out of this world, though it is currently completely unneccessary. 10gb+ has been somewhat common residentially for years.

[kalleboo@lemmy.world]

Most residential fiber currently is GPON with a 2 Gbps shared line using passive optical splitters, split up to 32 ways. Raising that shared line to 50 Gbps is a great upgrade.

[kalleboo@lemmy.world]

They're probably not building out 50 Gbps to the rice farmers

[cybersin@lemm.ee]

Enterprise adopted 100GbE networking around 2019. You can now buy used network cards for around $100 each.

Probably not where I am, that seems really low. I mean it depends if you use name brand or not. Often I don't use the name brand ones

But someone at AT&T would have to sell their yatch

[boonhet@lemm.ee]

Meanwhile, Telia in Estonia: "The Estonian customer doesn't prioritize connection speed or price, that's why we don't need to offer competitive speed/price ratios compared to what we have in other European countries"

[glitterbomb@lemmy.world]

That yacht is fine because someone else at AT&T rotated into a position at the FCC

[fpsxpert@discuss.online]

American companies being welfare queens, imagine that.

"Chona"

Hahah.

I have symmetrical 10 Gbps at home ($30/mo) and I'll agree. When it's nice when you have big updates, for most households 1 Gbps is going to be just fine. As you say, the vast majority of users are bottlenecked by Wi-Fi.

The bigger crime are all the asymmetrical connections that people on technologies like Cable TV networks have, where you get 1-2 Gbps down but only something tiny like 50 Mbps up. This results in crappy video calls, makes off-site/remote backups unfeasible, etc etc.

(or even Ethernet)

Technically, those 100+ Gbps fiber LAN/WAN connections used in data centers are also Ethernet, just not twisted pair.

That said recently I was in a retail store and saw "Cat8" cables for sale that advertised support for 40 Gbps copper ethernet! I wonder if any hardware to support that will ever be released. It is a real standard: https://en.wikipedia.org/wiki/100_Gigabit_Ethernet#40GBASE-T
