In the post-5G society, the volume of data traffic is expected to increase explosively due to new communication services, and the realization of advanced information and communication infrastructure is required. The research of ultra-high-capacity transmission using coupled 19-core optical fibers and advanced optical amplification has greatly advanced the development of technology for the realization of high-capacity, long-distance optical communication infrastructure in the future. In the future, we hope to further improve the efficiency of optical amplification technology, optimize MIMO digital signal processing, and explore the possibility of practical applications. The results of this demonstration were highly evaluated at the 48th Optical Fiber Communications Conference (OFC 2025, Venue: San Francisco, USA, March 30 (Sun) to April 3 (Thu), 2025), the largest international conference related to optical fiber communications, and accepted as the best hot topic paper (Postdeadline Paper), as announced on Thursday, April 3, 2025 (local time).
