Performance Improvement by Fibre Nonlinearity Compensation in 112 Gb/s PM M-ary QAM
Coherent communications Nonlinear optics fibers
2015/5/26
We demonstrate that digital back-propagation offers up to six-fold enhancement in transmission reach when nonlinear fibre impairments are compensated in coherently-detected 112 Gb/s PM m-ary QAM, with...
Fast Parallelized Simulation of 112 Gb/s CP-QPSK Transmission Systems using Stratified Monte-Carlo Sampling
Fiber optics communications Coherent communications
2015/5/26
A novel parallelized implementation of the split-step Fourier method on graphics processing units was developed. The combination of Monte-Carlo simulations with single and double precision yields a sp...
Scaling 112 Gb/s PDM-QPSK Hybrid Optical Networks
112 Gb/s Hybrid Optical Networks PDM-QPSK
2015/5/18
We experimentally and numerically determined the nonlinear transmission impairments for a hybrid PDM-QPSK/OOK network. Results are quantified via a nonlinear phase metric and can be used as design rul...
Comparison of RZ and NRZ Formats in 112-Gb/s PDM- QPSK Long Haul Coherent Transmission Systems
Coherent Transmission Systems PDM- QPSK RZ\NRZ Formats
2015/5/15
We show that 112-Gb/s PDM-QPSK coherent transmission systems with RZ pulse shape have better tolerance to ROADM filtering than NRZ, and time-interleaved RZ-PDM-QPSK outperform NRZ-PDM-QPSK in nonlinea...
Performance Comparison of 112 Gb/s PM-QPSK Transmission with NZ-DSF Dispersion Compensation Configurations for Lower Bit Rates
Dispersion Compensation Lower Bit Rates Performance Comparison
2015/5/14
We investigate transmission performance for 112 Gb/s PM-QPSK DWDM systems over NZ-DSF with configurations enabled by NZ-DSF dispersion characteristics. We find flexibility in dispersion compensation f...
112-Gb/s Polarization-Multiplexed 16-QAM on a 25-GHz WDM Grid
Polarization-Multiplexed WDM Grid
2015/8/6
We demonstrate intradyne detection of 112-Gb/s 16-QAM (14-Gbaud, polarization-multiplexed) in a 10-channel WDM environment on a 25-GHz grid. We show the robustness of a central channel to multiple add...
