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 algo-rithms,we achieve the total line transmission rate of 4.096 Tbit/s.The results prove that the bit error rates[BERs]for the 16QAM signals after 1000 km FMF transmission are below the soft-decision forward-error-correction[SD-FEC]threshold of 2.4 × 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.
