The speed record for data transmission using a single light source and optical chip has been shattered once again. Engineers have transmitted data at a blistering rate of 1.84 petabits per second (Pbit/s), almost twice the global internet traffic per second.
It’s hard to overstate just how fast 1.84 Pbit/s really is. Your home internet is probably getting a few hundred megabits per second, or if you’re really lucky, you might be on a 1-gigabit or even 10-gigabit connection – but 1 petabit is a million gigabits. It’s more than 20 times faster than ESnet6, the upcoming upgrade to the scientific network used by the likes of NASA.
Even more impressive is the fact this new speed record was set using a single light source and a single optical chip. An infrared laser is beamed into a chip called a frequency comb that splits the light into hundreds of different frequencies, or colors. Data can then be encoded into the light by modulating the amplitude, phase and polarization of each of these frequencies, before recombining them into one beam and transmitting it through optical fiber.
In experiments, researchers from the Technical University of Denmark (DTU) and Chalmers University of Technology used the setup to transmit data at 1.84 Pbit/s, encoded in 223 wavelength channels, down a 7.9-km-long (4.9-mile) optical fiber that contained 37 separate cores. For reference, the global internet bandwidth has been estimated at just shy of 1 Pbit/s, meaning this system could potentially handle all of that at once with plenty of room to grow.
This data transmission speed greatly exceeds the previous record of 1.02 Pbit/s, which was only set in May this year. A previous optical chip design, similar to that used in the new study, managed 44 terabits per second in mid-2020.

“Notes is supposedly finally going away in a few months.”
I never used Notes. But circa 1996 I was greatly impreessed by Howard Stern using it on his show. To communicate with his stooges. He referred to Notes at least once a day to be cool. Not that I had any idea what Notes was used for.
I bet there’s a 3rd party somewhere that will try to support it for a while.
It’s out there and not very good or responsive.
Email, calendaring, and database, fundamentally. There was quite a lot of application development in the Notes API back in the day. There were a lot of business critical apps running on it for a lot of folks, once upon a time.
Yeah, I can’t imagine. Time passed it by over a decade ago from what I can tell.
The wheels of progress turn ever so slowly.
All I do is make the ID files and install the client. The ETQ database stuff is in jurisdiction of the resident and knowledge expert.

Like _____ but living off grid is expensive these days. Here is one couple w baby that are doing it. Bodacious wife features in videos now to bring in the you tube viewers and advert $$$$. They live in British Colombia and some tropical place. They are growing many fruits and vegs and fishing too. They are not faking it but I suspect they have some trust funds

Thanks! I thought Notes was just for messaging. Once upon a time, it was as good as it got.
Record-breaking chip can transmit entire internet’s traffic per second
Another variation on the One Chip Challenge
Sorry. SciFi authors changed my life, I should have remembered better. I saw Ray Bradbury at a teacher conference in the 90s on the dangers of technology and teaching children (he could not be more profound). What a great speaker. He foresaw their reliance on technology and how much harm it would cause.
This quote was the most life-changing for a young teenager. I changed careers at least 10 times (cable splicer, avionics, robotics, writer, photographer, web designer, information technology, teacher, laser systems, etc...) because of it. When I got bored I moved on.
“A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects.

Billions of non-functional people plugged into AI-generated virtual reality. They will be farmed in various ways. The vast majority will pick the option for total immersion, which is to say forget base reality and have their bodies maintained in artificial 'wombs'.
Those of us who must do things in the physical world to maintain the infrastructure for the virtual world, will live in hyper-reality with AI-generated overlays on the physical world we encounter. The level of information available in your overlay will be commensurate with your job title and security clearance.
The really interesting thing to contemplate is whether what I'm describing above is the likely future or the present reality.
Page me when the data arrives before it’s sent…
Video conferencing tech and basically all things internet has been spearheaded by the porn industry.
Sorry bout choking your modem way back then. The 56kX2 dial up modem ruled the bulletin board!
LOL!
Very glad to see that you are OK.. had us worried!
You can use mine.....................
It’s apples and oranges.
60 trillion operations per second doesn’t tell me what the word size is, how many bytes per word, etc.
1.84 Petabit/s is just the speed at which data flows through the device.....................
