Impact of Intra-Channel Fiber Nonlinearity on Reduced- Guard-Interval CO-OFDM Transmission
Coherent communications Fiber optics communications Modulation
2015/5/26
Channel estimation for a reduced-guard-interval (RGI) CO-OFDM system shows a unique dependence on the training symbol design in the presence of intra-channel nonlinearities.Because smaller FFT sizes c...
Reduced-Guard-Interval CO-OFDM with Overlapped Frequency-Domain CD and PMD Equalization
Reduced-Guard-Interval CO-OFDM Overlapped Frequency-Domain CD PMD Equalization
2015/5/25
We propose an algorithm for CO-OFDM receivers to perform overlapped frequency-domain CD and PMD equalization before OFDM symbol demodulation. This approach enables OFDM transmission with a small cycli...
3× × 485-Gb/s WDM Transmission over 4800 km of ULAF and 12× × 100-GHz WSSs Using CO-OFDM and Single Coherent Detection with 80-GS/s ADCs
WDM Transmission GHz WSS CO-OFDM 80-GS/s ADC
2015/5/15
We demonstrate WDM transmission of three 485-Gb/s CO-OFDM channels with 16-QAM subcarrier-modulation, each received by a single coherent detection step.Transmission over 48 100-km ULAF spans and 12 wa...
Efficient Digital Backpropagation for PDM-CO-OFDM Optical Transmission Systems
Fiber optics communications Modulation
2015/6/9
We demonstrated experimentally that computationally-efficient digital nonlinearity compensation using backpropagation can increase the nonlinear tolerance of 61.7 Gb/s PDM-CO-OFDM by 2.2 dB in a 500 k...
Multi-staged Nonlinear Compensation in Coherent Receiver for 16,340-km Transmission of 111-Gb/s No-Guard-Interval Co-OFDM
Multi-staged Nonlinear Compensation Coherent Receiver Transmission No-Guard-Interval Co-OFDM
2015/7/20
Evaluation of the back-propagation step size for SPM compensation in a coherent receiver shows that setting step size to the amplifier section length extends the distance of 111Gb/s transmission from ...
