Significant improvements in the performance of electronic dispersion post-compensation enabled by beating interference compensation were experimentally demonstrated in a 112 Gb/s/λ WDM Nyquist-subcarrier modulation direct-detection system in transmission over distances up to 240 km.
We experimentally demonstrate 112Gb/s/channel 35GHz-spaced WDM direct-detection SSB Nyquist-SCM transmission over a record distance of 240km SSMF using a novel beating interference compensation method, which offers a 7.6dB required OSNR improvement, and 200% reach enhancement.
We proposed a novel SSBI mitigation technique with significantly lower DSP complexity. It was experimentally tested in 7×25 Gb/s WDM DD SSB 16-QAM N-SCM signal transmission over 480 km SSMF with a net ISD of 2.4 (b/s)/Hz.
We report on the first experimental demonstration of direct-detection dispersion pre-compensated single-sideband Nyquist-pulse-shaped 16-QAM subcarrier modulation (N-SCM) signal transmission using a signal-signal beat interference (SSBI) cancellation technique. The improvement in the system performance through the use of SSBI cancellation, which mitigates the nonlinear distortion caused by the square-law...
We investigate the effect of signal waveform symmetric clipping on the performance of dispersion-precompensated subcarrier modulated Nyquist-QPSK in uncompensated direct detection links. OSNR gains of 0.7 dB and 1.2 dB are achieved over 400 and 800 km of SSMF, respectively.
We report on the first experimental demonstration of 14 Gb/s direct detection single-sideband subcarrier modulated Nyquist QPSK transmission. Using electronic pre-compensation, transmission over 800 km of dispersion-uncompensated standard single-mode fiber was achieved.
