This letter proposes and experimentally demonstrates a cost-effective phase-modulation duobinary modulation scheme for improving self-phase modulation tolerance using a single modulator. Successful tr...
Impact of Pulse Shaping on the SPM Tolerance of Electronically Pre-compensated 10.7 Gb/s DPSK Systems
Fiber optics communications Modulation
2015/6/9
Pulse shaping for electronic pre-compensation systems using differential phase shift keying modulation is experimentally shown to provide a 1.9 dB increase of the nonlinearity threshold.
The signal and local oscillator acquire identical nonlinear phase shifts during propagation in a self-homodyne coherent system. We exploit this to achieve cancellation of the phase distortion caused b...
Experimental Demonstration of Joint SPM Compensation in 44-Gb/s PDM-OFDM Transmission with 16-QAM Subcarrier Modulation
Joint SPM Compensation PDM-OFDM Transmission Subcarrier Modulation
