INVITED PAPER Joint Special Section on Opto-electronics and Communications for Future Optical Network Petabit/s Optical Transmission Using Multicore Space-Division-Multiplexing

SUMMARY The paper presents ultra-high-capacity transmission technologies based on multi-core space-division-multiplexing. In order to realize high-capacity multi-core fiber (MCF) transmission, investigation of low crosstalk fiber and connection technology is important, and high-density signal generation using multilevel modulation and crosstalk management are also key technologies. 1 Pb/s multi-core fiber transmission experiment using space-division-multiplexing is also described.
