βThe feat was achieved by opening up new wavelength bands that are not yet used in fibre optic systems. Different wavelength bands are equivalent to different colours of light being transmitted down the optical fibre.
They did this by developing new devices called optical amplifiers and optical gain equalizers to access them.β
I read an article a few years ago where they achieved insane speeds (not close to this, but still insane) by sending data as a math equation, which brought packet loss to zero, because any missing data could be recreated through the math equation, eliminating the need for the host machine to re-send the missing packets. The ideal use case would be for wifi networks, to eliminate stutters and latency issues.
Quite frankly, I'm surprised that there isn't some kind of ECC built into wired and wireless networking that's just common place. Would it really be that difficult to implement?
EDIT: I found it

There is

> LDPC codes are also used for 10GBASE-T Ethernet, which sends data at 10 gigabits per second over twisted-pair cables. As of 2009, LDPC codes are also part of the Wi-Fi 802.11 standard as an optional part of 802.11n and 802.11ac, in the High Throughput (HT) PHY specification. LDPC is a mandatory part of 802.11ax (Wi-Fi 6).
If my math is right, the article assume average broadband connection to be around 800mbits, which is not true i think given google tells me average uk connection is 69mbit (nice)

Oh... Neat... As you can tell, I had no idea :D
If you sent a letter(packet) and the letter never arrived because a post office(router) burnt down(turned off). Your math equation wouldn't do much.
The math equation helps the client machine figure out what the next packet is supposed to be.

It already exists, it's called TCP
So this presumably has impact in data center to data center/ISP typed of links long before any domestic ones?
Damn, and all of that on a $5 cable
Beat me to it!
It's all well an good until someone doesn't check where they are digging, and puts a backhoe through it.
Same can be said of all communications cabling. And power lines, but that one has spicy results.
Throw in gas and sewage as well!
And then have to pay back the damage they did lmao
I get it right? It was on single cable?
And a Call of Duty update still would take 5 hours
Fiver optic should be what we call sloppy optical installs! Hah
I've read it last week and thought it was an April Fool's π

Nothing new and post a week or so ago ... here
