OSNR Monitoring Technique for PDM-QPSK Signals Based on Asynchronous Delay-Tap Sampling Technique
Fiber optics communications Fiber optics links subsystems
2010/6/4
We propose and demonstrate a new technique for monitoring the individual OSNR of each polarization tributary of PDM-QPSK signals. The results show that the performance of this technique is not sensiti...
Nonlinear Penalty Reduction Induced by PMD in 112 Gbit/s WDM PDM-QPSK Coherent Systems
Nonlinear Penalty PMD WDM PDM-QPSK Coherent Systems
2009/7/20
We show by simulation that when linear PMD is fully compensated by the receiver, the presence of DGD along the link reduces the amount of residual nonlinear penalty in 112 Gbit/s PDM-QPSK coherent sys...
Dispersion Management in WDM Coherent PDM-QPSK Systems
Dispersion Management WDM Coherent PDM-QPSK Systems
2009/7/20
We show that dispersion management with DCF does not outperform electronic dispersion compensation for WDM coherent NRZ-PDM-QPSK systems, but for time-interleaved RZ-PDM-QPSK systems,dispersion manage...
System Benefits of Temporal Polarization Interleaving with 100Gb/s Coherent PDM-QPSK
System Benefits Temporal Polarization Interleaving PDM-QPSK
2009/7/20
We demonstrate, over a NZDSF link, that the system benefits provided by the temporal interleaving of polarization tributaries of 100Gb/s coherent RZ-PDM-QPSK data depend on the WDM system configuratio...
Nonlinear Phase Noise Mitigation by Polarization Mode Dispersion in Dispersion Managed coherent PDM-QPSK Systems
Nonlinear Phase Noise Mitigation Polarization Mode Dispersion Dispersion Managed coherent PDM-QPSK Systems
2009/7/17
We show by simulation that PMD helps reduce nonlinear phase noise in single-channel coherent PDM-QPSK systems at both 43 and 112 Gbit/s, with improved resilience at 112 Gbit/s.
Suppression of Inter-Channel Nonlinearities in WDM Coherent PDM- QPSK Systems Using Periodic-Group-Delay Dispersion Compensators
Inter-Channel Nonlinearities WDM Coherent PDM- QPSK Systems Periodic-Group-Delay
2009/7/17
We show that periodic-group-delay dispersion compensators can significantly suppress inter-channel nonlinearities in a WDM coherent polarization-division-multiplexed quardrature-phase-shift-keying sys...
Numerical Monte Carlo Comparison between Coherent PDM-QPSK/OOK and Incoherent DQPSK/OOK Hybrid Systems
Numerical Monte Carlo PDM-QPSK/OOK Incoherent DQPSK/OOK Hybrid Systems
2008/8/4
We asses through Monte Carlo simulations PDM-QPSK/OOK and DQPSK/OOK Hybrid systems perfor-mance. DQPSK works better with optimal dispersion-management. PDM-QPSK is more robust to system impair-ments.
