Frequency-switching Coherent Reception for Hardware-efficient High-baud-rate Optical Transmission Experiments
Hiroshi Yamazaki, Kohki Shibahara, Masanori Nakamura +3
We investigate frequency-switching coherent reception (FSCR), a hardware-efficient technique for offline coherent optical signal characterization in laboratory environments, enabli…

389.3-Tb/s 1017-km C-band Transmission over Field-Installed 12-Coupled-Core Fiber Cable with >12-Tb/s Spatial MIMO Channels
Akira Kawai, Kohki Shibahara, Megumi Hoshi +16
We demonstrate 4.65-THz WDM/SDM transmission of 140-Gbaud PS-QAM signals over field-installed 12-coupled-core fiber cable with standard cladding diameter, achieving a record 0.455…
