Abstract (in Japanese) (See Japanese page) 
(in English) This talk provides an overview of advanced space division multiplexing (SDM) technologies that we have developed over the past few years for realizing long-haul SDM transmission systems. Differential mode delay (DMD) and mode dependent loss (MDL) remain dominant transmission impairments in fewmode fiber (FMF) transmission. A novel transmission technique that cyclically permutates spatial mode signals in every span avoids DMD-induced pulse broadening, and intermodal interference canceler significantly mitigates MDL impacts on mode division multiplexed signals. By combining these techniques, we have successfully demonstrated record-long SDM transmission experiments over FMFs with transmission reach exceeding 2500 km for a 12-core × 3-mode multicore FMF and 6300 km for a single-core FMF.
