We demonstrate a pilot-symbol assisted joint polarization carrier phase estimation technique that detects cycle slip and avoid error propagation. Coherent detection without differential coding is feas...
We investigated the optimized signal condition of the combined 8-QAM and QPSK subcarrier modulation for optical OFDM. The performance improvement was confirmed by WDM transmission experiments with the...
We study transmission of 40 Gb/s signals using coherent RZ-QPSK with and without polarization multiplexing using 100km large effective area fiber-spans and dual-stage EDFAs with mid-stage dispersion c...
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...
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...
Dependencies on segment number, dispersion map, and fibre launched power were investigated experimentally and numerically. Uncompensated 25 spans standard SMF link can enjoy net Q gain of 1.7dB with 2...
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...
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 present a comparison of adaptive electronic PMD equalizers for coherent phase - and polarization-diversity QPSK receivers using the multicanonical Monte Carlo method . A 5-tap equalizer using the C...
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.
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...
Combined effect of polarization mixing and Differential Group Delay (DGD) on sinusoidal and random jitter tolerance is investigated. Requirements for tolerable DGD, loop bandwidth and loop delay are e...
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.
By using PolMux-RZ-QPSK modulation format and digital coherent detection, we have demonstrated 20×112Gbit/s DWDM transmission over 1540km of SSMF without using Raman amplification or optical dispersio...
