Although high-speed wireless technologies like Wifi 6E and 5G dominate news headlines, analog, and optical cables are still the backbone of the internet, and for good reason. Researchers in Japan just set a new fiber optic data transmission record with a technique that’s compatible with existing cable infrastructure, meaning a real-world implementation is entirely possible, and not just limited to a laboratory setting.
Researchers from Japan’s National Institute of Information and Communications Technology (NICT) successfully sent data down a custom multi-core fiber optic cable at a speed of 1.02 petabits per second over a distance of 51.7 km. That’s the equivalent of sending 127,500 GB of data every second, which, according to the researchers, is also enough capacity for over “10 million channels of 8K broadcasting per second.” As New Atlas points out, that’s also 100,000 times faster than the promised next generation of high-speed gigabit connections providing internet to home users.

In this experiment, by broadening the Raman amplification bandwidth to the full S-band and using customized thulium-doped fiber amplifiers (TDFAs) for S-band and extended L-band erbium-doped fiber amplifiers (EDFAs), we were able to use a record 20 THz optical spectrum with total of 801 x 25 GHz spaced wavelength channels, each with dual-polarization-256 QAM modulation for high spectral density in all wavelength bands.
The most important part is that this second breakthrough relies on hardware and techniques that are completely compatible with conventional transceiver hardware that is already in place across the country. New fiber optic cabling will need to be installed, but since the researchers limited the size of their multi-core cable to standard dimensions, it would be completely compatible with existing infrastructure, greatly reducing upgrade costs. As 5G becomes more widespread, and with 6G just around the corner, the country’s demand for data is going to continue to increase by leaps and bounds, but an innovation like this promises to give internet providers a sizeable head start for at least a few years.
Everyone will have a SELMA like on old Time Trax.
“Haha - my first was 2400 baud...just awful, “
My first was 300 baud. It sure beat punching cards!

While connectors could be used, I thought that fusion splicing was still the main technique used in splicing cables, such as after a dig up.
Mine too. Soooo many years ago. An Atari 1030 300 baud modem attached to an Atari 800 using Kermit to access Bulletin Board Systems (BBS).
Thank you.
Awesome news...
Does this means that here on FR we will have access to events that are to occur several weeks in the future?...

I was born late enough to avoid that era. Probably the most primitive thing was writing on paper a 6502 assembly program, converting it to machine code HEX values, and using a HEX keypad to program into battery backed RAM module...which you would then drop into the runtime HW. I controlled a bunch of I/O LED’s - made the “Knight Rider” effect. At 14 I thought it was pretty cool.
Interestingly, as I grew up in the UK - every phone call cost money, so we didn’t really get into the whole BBS/modem thing.
I still have my 300 baud modem, was happy to get a 1200 baud modem later. Made the characters paint faster on the screen from left to right when accessing a BBS. A lot of progress within a decade to faster modems, our wallets had to keep up with cash outlays.
And they’ll be able to empty your bank account that much faster!
I remember entering code via switches in 1965.
:) ...I won’t ask how much RAM it had.
THINK OF ALLLLL THE HENTAI

Well Frick, I’m stoked .....
Wrong, not all of it need be porn. (Although that should be enough to even keep Hunter and his dad busy for a while.)
Do you recall the bandwidth problems we experienced during the Iraqi Freedom operations, for example?
There is more than one way to utilize bandwidth.
