Wavelength-space permutation switch with coherent PDM QPSK transmission for supercomputer optical interconnects
Optical interconnects Coherent communications
2015/6/4
We experimentally study the performance of an economically-viable, high-capacity supercomputer optical interconnect employing wavelength-space optical packet switching,polarization division multiplexe...
We report the transmission of 155 channels with 100Gbit/s PDM-QPSK modulation over 7200km of pure silica core fibre, exploiting hybrid Raman-EDFA amplification and digital coherent detection. A record...

Dispersion Management WDM Coherent PDM-QPSK Systems
2015/7/20
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
2015/7/20
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 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.

Inter-Channel Nonlinearities WDM Coherent PDM- QPSK Systems Periodic-Group-Delay
2015/7/17
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...

WDM Channels When Assessing Performance Coherent PDM-QPSK Overlaying Legacy Systems
2015/7/15
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 vs. Dual-Carrier Transmission of 100Gb/s coherent PDM-QPSK over NZ-DSF Fibre
Single-Carrier Dual-Carrier Transmission coherent PDM-QPSK over NZ-DSF Fibre
2015/7/14
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
Numerical Monte Carlo PDM-QPSK/OOK Incoherent DQPSK/OOK Hybrid Systems
2015/8/4
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.
