50gbps **shared line using passive optical splitters. Bit misleading there Chona, nobody is getting an actual 50gbps connection to their house.
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.
"Chona"
Hahah.
Most residential fiber globally currently is GPON with a 1-2 Gbps shared line using passive optical splitters, split up to 32 ways. Raising that shared line to 50 Gbps is a great upgrade.
Its not that out of this world, though it is currently completely unneccessary. 10gb+ has been somewhat common residentially for years.
Getting real tired of these „China is 30 years ahead of us“ clickbait headlines on an almost daily basis. They‘re always completely overblown and sadly really warp the public perception of the country and their government.
I'm sure the hardware for 50Gbps optics wouldn't be cheap for the consumer 🤣
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 🤣
I just checked on eBay, and there are multiple listings for single port 100 GbE Mellanox (now nVidia) Connect-X 4 cards in the $60-100 range.
My mistake, I was thinking 100Gb fiber. Even the knock off switch SFPs are hundreds of dollars each.
The “innovation” in the article is passive tech for fiber to the room (FTTR), specifically made to be low cost and easier to implement. It’s also how your computer might get that 50Gbit - it’ll have to be wired in with a fiber connection. It’s not happening over WiFi (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, approved way back in 2016: https://en.wikipedia.org/wiki/100_Gigabit_Ethernet#40GBASE-T
Those cables are hard to terminate properly. There's an outer grounding sheath that needs to be connected up at both ends. Except for short connections, I find it easier/cheaper to use fiber.
There is nothing preventing housing being built with it, so it's still viable, if currently drastic overkill. Most end-users wont have fiber cards in PCs to begin with, but that isn't insurmountable either.
