【摘要】 We experimentally transmit eight wavelength-division-multiplexing （WDM） channels,16 quadratic-amplitude-modulation（QAM） signals at 32-GBaud,over 1000 km few mode fiber （FMF）.In this experiment,we use WDM,mode division multiplexing,and polarization multiplexing for signal transmission.Through the multiple-input–multiple-output （MIMO） equalization algorithms,we achieve the total line transmission rate of 4.096 Tbit/s.The results prove that the bit error rates （BERs） for the16QAM signals after 1000 km FMF transmission are below the soft-decision forward-error-correction （SD-FEC） threshold of2.4×10^-2,and the net rate reaches 3.413 Tbit/s.Our proposed system provides a reference for the future development of high-capacity communication.更多还原
