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.

Petabit Ping!....................
Absolutely astonishing! I worked in the optical networks division of Nortel Networks for a while right before the tech crash in 2000. It was a wild time. The industry was laying cables with 1,000 strands of fiber and we were lighting only a few 10 Gbps DWDM channels on each strand. There was huge unused capacity on the one lit strand. Performance had gone up many orders of magnitude and prices came down a few orders of magnitude. The market got oversaturated very quickly and the whole industry went BOOM after that build-out. Here we are 22 years later and trucks for competing companies are laying last-mile fiber everywhere around Coeur d’Alene, pushing fiber to the home.
Who is going to use petabit networks? For what applications?

Porn... porn has been the fastest adopter of all things internet over the past 30 years.
It’s amazing how fast tyrants will be able to spread a monumental volume of lies and gaslighting in one second.
Petabits of data and not one tiny bit of truth blowing across the Internet every second.
Lotus Notes will stop it cold.
What’s the per month charge for this type of service?
Can I bundle it with my cell service too?
It sounded like science fiction at the time and that was only 25 years ago - late 1990s.

Download the whole knowledge base of mankind to your home server and live in the wilderness off grid. :^)

Is there fiber that can propagate that bandwidth without so much group delay that the data cannot be recovered after a short distance? It is impressive, but there may be more problems to solve.
VR based graphics or 8k\16k graphics for everyone.
Yes, something will surely be done with all that bandwidth.
Immersive high-resolution video streaming comes to mind. Gamers are going to love this.
And all that traffic consisted of cat videos.
Already 200TB SSDs are available. 1000TB SSDs might be around the corner. We had to get this technology from aliens. Ha.
Comcast will still have you holding for an hour
I’m also thinking Elon Musk will love this for his Starlink satellite internet. Forget fiber, the satellites will use this to talk to each other in orbit.
Can you read it? Can you process it?
