EXAT 2025 Concludes Successfully
The 8th International Symposium on Extremely Advanced Transmission Technologies (EXAT 2025) concluded on a high note in Himeji, Japan, with over 100 participants from around the world gathering to exchange cutting-edge research. There were vibrant exchanges between exhibitors and participants during the coffee breaks. Highlights included the Poster Award, with winners recognized during the closing ceremony, as well as excursions to the historic Himeji Castle and Japan's synchrotron radiation facility, SPring-8. Attendees also enjoyed memorable social events, such as the welcome reception at Himeji Monolith and the banquet at Harimanokuni Sousha, which offered a taste of local culture and hospitality.
We sincerely thank everyone who joined us and contributed to the success of the conference. We look forward to welcoming you again in EXAT 2027, by which time we hope to see even further advancements in optical communication.

Welcome
Welcome to the 8th International Symposium on Extremely Advanced Transmission Technologies (EXAT 2025). The objective of this symposium is to discuss the current status and future trends of 3M (multi-core, multi-mode. multi-level modulation) technologies. Plenary and invited speakers will give an overview of on-going SDM related research projects as well as an outlook towards the future of optical communications. Furthermore, an extensive poster session will also provide opportunities for discussions and information exchange on the latest hot research topics in this field.
About EXAT
The EXAT community in Japan initiated the development of SDM technology in 2008 and since then has been playing a leading role in the investigations of the so-called 3M (multi-core, multi-mode, and multilevel modulation) technologies. The scope of EXAT includes novel optical fibers, components, and transmission and node technologies for space-division-multiplexing (SDM). Since 2010, the EXAT committee has been organized as a technical committee of the Communications Society, the Institute of Electronics, Information and Communication Engineers (IEICE). For more details on the Technical Committee on Extremely Advanced Optical Transmission Technologies (EXAT) and its activities please visit the EXAT website.
EXAT 2025 is cosponsored by the Technical Committee on Extremely Advanced Optical Transmission Technologies (EXAT) of the IEICE Communications Society (IEICE-CS) and National Institute of Information and Communications Technology (NICT).
