摘要
We experimentally demonstrated the transmission of 40 × 433.6- Gb/s Nyquist wavelength-division-multiplexing (N-WDM) optical timedivision- 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 100GHz, yielding a spectral efficiency of 4.05b/s/Hz. The bit-error ratio (BER) of all channels is less than the preforward- error-correction (pre-FEC) limit of 3.8 × 10-3 after 2800-km SMF- 28 transmission.
