41.6 Tb/s C-band SDM OFDM transmission through 12 spatial and polarization modes over 74.17 km few mode fiber

We demonstrate the transmission of 12 spatial and polarization modes multiplexed on 255 optical channels in ultra-dense WDM using OFDM across the full C-band over 74.17 km 6-mode fiber. An aggregate bit rate of 41.6 Tbit/s is achieved.
