Special Section on Feature Topics on Latest Trends in Optical Networks

We have observed the steady progress that has been made in optical networking technologies thanks to of the extensive efforts made in the research and development of optical networks. We believe that further progress should be made as optical networks are expected to play important roles in future broadband and ubiquitous networks by expanding the network capacity, providing high-quality communication service, and improving reliability. This special section aims to promote better understanding of the latest trend in optical networks and to promote further research and development.
