Extremely high-frequency signals increased the data transfer rate to 10 Tb/s. This is much higher than the speed with which existing channels can transmit data, according to a study by scientists from the American Institute of Physics, published in the journal Applied Physics Letters.
Researchers used the same technology that allows high-frequency signals to pass through regular telephone lines. To do this, they used a device with two wires running in parallel inside a large-diameter sheath.
Then, the researchers created a 13 by 13 mm grid to output each possible input condition, as a result of which a 169 by 169 channel matrix was obtained, which provides a complete characterization of the waveguide channel.
After that, scientists sent extremely high-frequency signals at 200 GHz through a pair of copper wires. As a result, they were able to increase the data transfer rate up to 10 Tb/s – this is much more than the existing channel can transmit.
The paper notes that such a data transfer rate is only available at short distances, but in the future, scientists plan to refine the system to work with large distances.
