590-km Combined WDM/SDM Transmission over Few-Mode Fiber Supporting 12 Spatial and Polarization Modes
17 March 2013
We transmit 16 WDM 20-Gbd QPSK channels over 12 spatial and polarization modes of 590- km few-mode fiber at a spectral-efficiency-distance product of 9440 km bit/s/Hz. The transmitted signals are recovered using off-line 12x12 multiple-input multiple-output digital signal processing.
