32-bit/s/Hz spectral efficiency WDM transmission over 177-km few-mode fiber

We transmit 32 WDM channels over 12 spatial and polarization modes of 177 km few-mode fiber at a record spectral efficiency of 32 bit/s/Hz. The transmitted signals are strongly coupled and recovered using 12×12 multiple-input multiple-output digital signal processing.
