A group of researchers at the Network Research Institute of the National Institute of Information and Communications Technology (NICT, Japan), have succeeded in the world’s first large-capacity transmission experiment with large-mode multiplexing technology using 55 modes.
The researchers worked with colleagues at Nokia Bell Labs (USA), Prysmian Group (Prysmian, France, and the Netherlands), and the University of Queensland (Australia), to deliver data at a rate of 1.53 petabits per second, a record in any standard cladding diameter (0.125 mm) optical fibre to date, said the Institute.
It added that 55 modes were successfully multiplexed throughout the commercially adopted optical fibre transmission window (C-band), with a “dramatic increase” in spectral efficiency compared to conventional fibres and previous multi-mode transmission.
The Institute said a further expansion of transmission capacity can be anticipated by combining this technology with multi-band wavelength-division multiplexing technology.
This demonstration serves as an 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, it added.
More details about the experiment are available here.
