Record-breaking chip can transmit entire internet's traffic per second
New Atlas ^ | October 23, 2022 | By Michael Irving

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.

It probably is. I continue to be surprised.

Where was this tech back in the 1998 when I first joined FR. All of those days where the site would freeze because of some big breaking news story.

Now, like then, if this site is down, there is/was nothing on the internet worth reading.

“And all that traffic consisted of cat videos.”

And that’s why they call it PETAbits.

Who is going to use petabit networks? For what applications?
= = =

Not for your normal computer communication output.

But for monitoring your every video and audio activity.

I think I get it, but I need to find my slide rule to be sure. :)

(no, seriously, many modems at the time would choke while downloading a single JPEG)

Seemed like forever to get to the nipples.

Data testified in the episode of "Measure of a Man" that

"My total linear computational speed has been rated at 60 trillion operations per second."

How does this new chip measure up?

You might be surprised on what you can do with only 10mbit including streaming

My bills are high enough without wasting money

Wow, this means we can watch cute cat videos at 100 million HD.

A few weeks ago my credit card expired and so the Spectrum payment didn’t go through. It appears they immediately throttled the bandwidth from the normal 30 down to 3 Mb/sec. Still usable for everything we do except for some video, which would buffer. On submitting the new CC information a few days later, the bandwidth immediately increased to the normal 30.

“Who is going to use petabit networks? For what applications?”

The correct question is ‘What is going to use this to control us’

Understand the numbers if It’s name. Created by humans the numbers were.

I worked at a company that used fiber bragg gratings to deal with group delay. We made a tunable device that could be installed on any length of fiber. It was amazing that we could use a three inch long piece of encoded fiber to replace many kilometers of fiber wound on a spool. The company never made it, though.

The way things are going, it will be “Press 3 for English” in a few years.
