Researchers in Japan 'break transmission record' over 1,045km with three-mode optical fibre

Japan’s National Institute of Information and Communications Technology (NICT), in partnership with Fujikura, has demonstrated a transmission experiment over 1,045km with a data-rate of 159Tb/s. This was achieved using the recently developed three-mode optical fibre, which is capable of wide-band wavelength multiplexing transmission with standard outer diameter (0.125mm) that can be cabled with existing equipment.
