Latest data transmission is 26 terabytes per second, the equivalent of 700 DVDs. Not all the time in the world would be sufficient to watch that many. For the engineers, such sppeds are now possible, and the breakdown starts at the receiving end:

As no electronic processing methods are available for a data rate of 26 terabits per second, the team uses purely optical calculation in order to break down the high data rate to smaller bit rates that can then be processed electrically.
