Abstract
This paper presents the latest developments in the 3M technologies for next-generation optical communication, namely Multi-level modulation, Multi-core fiber and Multi-mode control for mode-division multiplexing. We also describe recent innovative technologies including ultra-wideband WDM transmission beyond conventional C and L bands, and novel hollow-core fibers enabling ultra-low loss below conventional fibers.
