Abstract
This paper describes the overview of special issues for the research and development on space-divisionmultiplexing
transport systems that consist of scalable transmission node and novel transmission fibers.
The topics of this issues covers network node architecture, integrated optical switching system with lowpower
optical amplification, optical wiring and interconnection, high-core-count multicore fiber, and
long-haul transmission performances verification with the capacity over 1 Pbit/s.
