Record breaking fiber transmission speed reported
NICT Network System Research Institute and Fujikura Ltd. (Fujikura, President: Masahiko Ito) 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. The researchers have successfully demonstrated a transmission experiment over 1045 km with a data-rate of 159 Tb/s. Multimode fibers have different propagation delays between optical signals in different modes that makes it difficult to simultaneously satisfy large data-rates and long distance transmission. This achievement shows that such limitations may be overcome.
