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

I work on PON and XGPON. Officially we work on a -25dB maximum, but I've seen circuits stable at around 30dB.

It's surprising how many bad splices you can ignore before it gets problematic.

-18.5dB is going to limit you to either a really good fibre path, or a really short one. Unless you have options with long-range SFPs? The constant progress keeps my job interesting at least.

And then he blocked me XD

All these egotistical children with nothing to be proud of

[softestsapphic@lemmy.world]

Lmao the irony

You have serious ego issues that you will need self reflection to fix.

I'm working on long range stuff so I'm not so familiar with PON specifically. Maybe I made some bad assumptions. Stable at -30 dBm receive sounds really impressive.

The one I was talking about is this, with 18.5 dB total budget, that is, min +4.5 dBm transmit, and min -14 dBm receive. This one is built with an APD.

In my kind of application, without splitter, this will get you about 30-40 km. We've got one of a slightly older type with 18 dB budget running between Fribourg and Bern for example.

I realize that PON stuff is quite different with the time slitting and I think wavelenght splitting too, at least in XGS-PON, but I was thinking the pure laser and diode physics would need to be the same.

For -25 dBm minimum the most similar of the ones we currently have would be this one which manages -26.9 dBm and is one of the ones with a SOA built in, or for the 10G stuff this one, which manages min -23 dBm but with only an APD and no SOA.

I'm thinking their 50G stuff must be closer to 100G than 10G transceiver design. So I wonder if they manage to make it without SOA.

China has this covered hands down. If you say Winnie, two mean looking Chinese men appear behind you.

[surewhynotlem@lemmy.world]

Oh, maybe. I'm not familiar with bandwidth utilization in China.

[synicalx@lemm.ee]

Very cool and they should keep doing this, but no one’s CPE is going to be able to do anywhere near this speed unless they plan on giving everyone large enterprises routers for home use.

Who blocked you?

[redditrefugee69@lemmynsfw.com]

Feel free to elaborate. I have no idea what you're talking about other than it seems like tankie screeching to me.

[dywmtco@lemmynsfw.com]

the us will be lucky if it exists at all in the future

[ilikeboobies@lemmy.ca]

Yeah, one thing at a time

We’ll be around. We may not be a democracy but we’ll be around.

China though, it’s cooked .

there could be some new thing that no one has not even bothered to think about because of the limitations. Imagine streaming back when downloading few kilobytes for an hours was considered reasonable, people would have laughed at the very thought of it.

. Only a $40 Meta subscriptio

I tried to upload some 8k 360 footage to FB before I left it
"We're sorry, but an error has occurred"

Tried over several days, no good. tried again a month later, still no good.

Camera is more or less useless if you can't host the footage anyway

We're not using the bandwidth we have. Many US cities have service with 1Gbps download speed available. I have it for my own reasons. Servers are the bottleneck; they rarely even reach half that speed.

If we're not using 1Gbps, why should we believe something would pop up if we had 50Gbps?

Now, direct addressing where everyone can be a server and bandwidth utilization is spread more towards the edges of the network? Then you have something that could saturate 1Gbps. But you can't do that on IPv4.

[nopermissions@sh.itjust.works]

They're over here talking about 50Gb XGS-PON for residential like anyone is actually going to use it. I bet their end users will still complain about slow speeds.

[kalleboo@lemmy.world]

I have a cheap noname chinese switch with 2x10gbit ports and 4x2.5 Gbps ports, so I have the 10 Gbit ports to the internet and my computer, and use a 2.5 gbps port for my NAS, everything else is 1 gbit

Not just this, I'm not sure if they checked about LGBT rights in China.

From outside the first world Trump and his supporters look scandalist, loud, corrupt and incompetent. Which is sad. But they don't seem fascist most of the time.

Anyway, if we take Putin, he's done many things, one thing he's consistently never done is say antisemitic or easily recognizable fascist things. There is some popularity of Ivan Ilyin around him, who is a Russian emigrant fascist philosopher, though (who apparently wanted to fix problems with Mussolini and the own such "thinkers" of the White movement, except he was on the dumber side, so compared to his writings Mein Kampf seems intellectually elegant).

Virgin will definitely be faster, they'll do up to a gigabit. Hopefully open reach rolls out fibre to you soon. I only got the fibre to my house last month!
