The National Institute of Information and Communications Technology (NICT, President: Hideyuki Tokuda, Ph.D.) has successfully demonstrated a world-record for switching capacity of 53.3 Tb/s for short-reach data-center networks. This demonstration makes use of spatial division multiplexing (SDM) over multi-core optical fibers (MCFs) and a newly developed high-speed spatial optical switch system, enabling full packet-granularity. We believe this newly developed data-center network provides a significant improvement of network efficiency and end-to-end energy consumption per bit compared to today's optical circuit, fully-electronic packet switching networks. The results of this demonstration were selected for presentation as a post-deadline paper at the prestigious 43rd European Conference on Optical Communications (ECOC) in Gothenburg, Sweden, on September 21, 2017.
