Don't get the cart before the horse

Don't get too excited.  The devil in the details will be the required changes to the Tx/Rx interfaces as I seriously doubt that a simple firmware, microcode or OS upgrade to the various Juniper/Cisco/Alcatel/etc gear will make this work, not to mention potentially new ASICs or processors to handle the load.

This won't be a zero cost upgrade by any means, and even if it were, I'm sure the companies mentioned would be sure to make the things I listed required in order to make a buck.

That all said, if the fiber doesn't have to be changed, that is pretty awesome compared to another recent announcement about a faster speed increase (2.5Tbps) using Orbital Angular Momentum (OAM) by researchers at Boston University and the University of Southern California.

Great! Now we can start using the massive amount of fiber media that was laid in the late 90s and early 2000s!  Glad the telecom companies thought ahead, because there wasn't a need for that much infrastructure at the time.

@AnandY, I think there will be intensive capital that will be in the development so we will see some initial cost associated with it, but like you said - having the physical infrastructure already in place is huge...

@ Nancy Golden, Building on the argument of naperlou, you opined rightly that achieving such mega transmission rates over existing lines is actually the real breakthrough. It simply means that we don't have to change the existing data transmission infrastructure which will make the transition to higher data transmission a piece of cake and would not require intensive capital.

It is simply awesome the rate at which data can travel and the distance it could cover without any distortion. Even though it is in experimental stages, yet it promises a lot. Using noise removeal techniques to improve the data speed is really innovative idea.

This sounds like the smart, bleeding edge stuff Bell Labs is well known for. It sure would be great if we could use all of that fiber that's been laid down.

You make an important point, naperlou - regarding using existing fiber. Not having to lay new lines and simply increase the speed by modifying the transmission scheme is exciting. Since "back in the day" the mention of fiber optics held so much promise and it looks like it continues to do so. Bell Labs gave us the transistor and continues to innovate: Here is an intereesting link to some of their other contributions:

Bell Labs has been around for a long time.  They have innovated for almost 100 years.  This is another interesting innovation. 

From what the article says, it seems that this scheme can use existing fiber, since it is the transmission scheme that is modified.  The speeds are fantastic, and over the distances mentioned they will contribute to more efficient communications.
