A group of
scientists from the Eindhoven University of Technology and the University of
Central Florida had published scientific articles with the
results of the experiment on record speed data transmission over fiber optic
cable. Using a new type of optical fiber, they managed to register a speed of
255 terabits per second, which is a record today.
New optical fiber comprises seven different cables for
transmission of information whereas the the usual optical fiber comprises a
single cable. So appeared a possibility significantly increase a speed. Moreover, for each channel, researchers have
introduced additional two orthogonal dimensions for data transmission, i.e. for
each channel rate had tripled. Due to all of
these improvements was possible to increase the speed up to 255 terabits / s,
which is 20 times more than the current norm now for optical fiber 4-8 terabits
/ second.
The diameter of is developed optical fiber is 200 microns, so that the entire cable is
not much bigger than that used today. At
the same time it can be significantly increased the capacity of communication
channels.
