We experimentally demonstrated the transmission of 40 × 433.6-Gb/s Nyquist wavelength-division-multiplexing (N-WDM) optical time-division-multiplexing (OTDM) over 2800-km single-mode fiber (SMF)-28 with Erbium-doped fiber amplifier (EDFA)-only amplification, adopting polarization-division-multiplexing carrier-suppressed return-to-zero quadrature-phase-shift-keying (PDM-CSRZ-QPSK) modulation as well as post filter and 1-bit maximum likelihood sequence estimation (MLSE). Each channel occupies 100 GHz, yielding a spectral efficiency of 4.05 b/s/Hz. The bit-error ratio (BER) of all channels is less than the pre-forward-error-correction (pre-FEC) limit of 3.8 × 10(-3) after 2800-km SMF-28 transmission.
