Scientists were able to transfer data at a speed of 1 Tbit / s through a pair of copper wires

Using technology appliedTo send signals over telephone lines, researchers have achieved data transmission through a pair of copper wires at a speed of terrabits per second and a frequency of 200 GHz.

Although multiple signal separation technology,passing through one channel existed before, but questions remained regarding the effectiveness of its use at higher frequencies. To test this transfer, a team from the American Institute of Physics used experimental measurements and mathematical modeling toestablish the distinctive characteristics of the incoming and outgoing signals in the waveguide.

They used a device with two parallel wires inside a thick shell, making it easier to enhance waveguide mode mixing without interference. 

Increasing frequency increases bandwidthand the amount of data passing through the channel, if not distorted. To confirm and characterize this behavior, scientists measured the spatial distribution of energy at the output of the waveguide.

Physicists have created a 13 by 13 mm grid foroutput of each possible input condition, resulting in a matrix of 169×169, providing a complete characteristic of the waveguide channel. The measurement results demonstrated the superposition of waveguide modes in the channel and made it possible to estimate data transmission rates.

Experiments showed that on a smalla distance of a pair of copper wires can support the speed of information movement up to 10 Tbit / s, which confirms the further feasibility of applying this approach to high-frequency transmission, when sources and detectors reach an appropriate level.
