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...

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...

We experimentally analyze WDM nonlinear impairments brought by co-propagating 10Gb/s NRZ channels onto a 100Gb/s PDM-QPSK channel. The PDM-QPSK channel can experience strong nonlinear interactions eve...

Single-Carrier Dual-Carrier Transmission coherent PDM-QPSK over NZ-DSF Fibre
2009/7/14
We experimentally compare 100Gb/s PDM-QPSK in single-carrier and dual-carrier configuration over 800km of NZ-DSF fibre. Using 40Gb/s P-DPSK and 10Gb/s OOK neighbours the lower tolerance to nonlinear e...
Numerical Monte Carlo Comparison between Coherent PDM-QPSK/OOK and Incoherent DQPSK/OOK Hybrid Systems

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.

The tolerance to PMD of 100Gb/s PDM-QPSK systems is investigated in linear and nonlinear regime.Experimental results show that nonlinear effects decrease the robustness of the system against PMD.
