Scientists were able to transfer data at a speed of 1 Tbps through a pair of copper wires

Using the technology used to sending signals over telephone lines, the researchers achieved the transmission data through a pair of copper wires at terabits per second and a frequency of 200 GHz.

Although the technology of separating several signals passing through one channel existed in the past, questions remained related to the effectiveness of its application at higher frequencies. To test this transmission, a team at the American Institute of Physics used experimental measurements and mathematical simulations to establish distinctive characteristics incoming and outgoing signals in the waveguide.

They used a device with two parallel wires inside a thick shell, which made it easy to amplify waveguide mode mixing without interference.. 

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

Physicists created a 13 mm by 13 mm grid to output every possible input condition, resulting in a 169×169 matrix that provides full waveguide channel response. The measurement results showed superposition of waveguide modes in the channel and made it possible to estimate the data transmission rates.

Experiments have shown that, at a short distance, a pair of copper wires can support information transfer rates up to 10 Tbit / s, which confirms the further expediency of applying this approach to high-frequency transmission when sources and detectors have reached the appropriate level..

We also reported earlier that tellurium nanowires paved the way for next generation electronics.
