A group of researchers from the Network Research Institute of the National Institute of Information and Communications Technology (NICT, Japan) have set a new speed record for data transmission through a standard diameter optical fibre.
The team was able to transmit at a data rate of 1.53 petabits per second (Pbit/s), a record in any standard cladding diameter (0.125 mm) optical fibre to date.
NICT, Japan worked in collaboration with Nokia Bell Labs (USA), Prysmian Group (Prysmian, France, and the Netherlands), and the University of Queensland (Australia) in the world's first large-capacity transmission experiment with large mode multiplexing technology using 55 modes.
The experiment also reported data-rate of 1.53 petabits per second, a record in any standard cladding diameter (0.125 mm) optical fibre to date. 55 modes were successfully multiplexed throughout the commercially adopted optical fiber transmission window (C-band), with a dramatic increase in spectral efficiency compared to conventional fibres and previous multi-mode transmission.
A further expansion of transmission capacity can be anticipated by combining this technology with multi-band wavelength-division multiplexing technology. This demonstration serves as important step in the maturity of high mode-count multi-mode transmission technology and the development of Beyond 5G and subsequent information and communications infrastructure technology.
