Title: Tech Research to Increase Fiber Bandwidth by 400*

Apparently they've developed a method of increasing bandwidth in a fiber optic cable by 400 times.
How do they do this? It's easy, first figure out what the problem is.

Problem: Light travels in a wave, and in a fiber optic cable the wave can be distorted by many factors. Quality of cable, outside light, black holes, the gravity your mother generates....
Essentially this causes the signal to degrade which makes it take longer to send correct messages.

Solution: Wrap two fiber optic cables together. But wait! Wouldn't that just double speed?
Not if you do it in a smart way...
Lets say light travels in a sine wave from infinity to -infinity. Lets say somewhere down the line at a particular point in time it gets distorted from 8 to 5. You're screwed.
But these smart guys thought, hey wouldn't both cables be distorted the same way? Ideally yes.
Therefore what if you make the second fiber cable mirror the other?
If fiber optic cable 1 is 8, then the second one is -8.
Now if they both get distorted, first turns to 5, second turns to -11. If you'll notice....

The difference between distorted and undistorted is the same!
So the solution is simply to send the message as the difference between 2 signals in the same cable.
Distortion won't degrade the signal. Which makes a lot faster connection.


Get ready for the future. It's coming.

Wow.  400 gigabits per second = 50 gigabytes per second.  That's insanely fast, even faster than the fastest RAM and SSDs.  Memory and storage will become the bottlenecks of data transfer.  The wires will be able to move data at the speed of light, but the machines will never be able to match it.  As a person who used dial-up internet for years, this is difficult to comprehend.

Now we need fiber-optic computers that can keep up!
