System Benefits of Electrical Dispersion Pre-Compensation for Non-Dispersion-Managed PDM-WDM Transmission

We studied the system benefits of applying dispersion pre-compensation implemented using programmable DAC, on the performance of 32.5 Gbaud root-raised-cosine pulse-shaped PDM-WDM BPSK, QPSK, and 16QPSK. With 50% dispersion pre-compensation, 1.5 improvelement on optimum Q-factor is observed for BPSK. 0 Improvement was observed for QPSK and 16QAM.
