Researchers in Japan have developed a 3-mode optical fiber, capable of wide-band wavelength multiplexing transmission with standard outer diameter (0.125 mm) that can be cabled with existing equipment. They have demonstrated a transmission experiment over 1045 km with a data-rate of 159 Tb/s. Converting the results to the product of data-rate and distance results in 166 Pb/s×km. This is the world record in a standard outer diameter few-mode optical fiber and the largest data-rate over 1000 km for any kind of standard-diameter fiber… read more.
