257-Tbit/s Partial MIMO-based 10-Mode C+L-band WDM Transmission over 48-km FMF

A 10-mode multiplexed 336-WDM transmission of dual-carrier 12-Gbaud DP-QPSK signals over 48-km was successfully demonstrated only with 2×2 or 4×4 MIMOs by using weakly-coupled fewmode fibre. We achieved the record fibre capacity of 257-Tbit/s per single-core fibre.
