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...
Ultra-long 10 Gb/s Unrepeatered WDM Transmission up to 601 km
Fiber optics communications Phase modulation
2015/6/9
We perform ultra-long unrepeatered transmission at 10 Gb/s, applying the most advanced technology: RZ-DPSK, third-order Raman pumping and ultra-low loss fiber. We transmit four channels over 574 km an...
Stability of Amplified DPSK WDM Transmission against Raman Crosstalk Effects
Pulse propagation temporal solitons Raman effect
2015/6/5
We investigate Raman-crosstalk-induced amplitude dynamics in amplified DPSK WDM transmission. We prove existence and stability of equilibrium states with nonzero amplitudes in all channels. Our result...
Scaling of Nonlinear Threshold in WDM Transmission Systems using Electronic Precompensation of Intrachannel Nonlinearities
Nonlinear Threshold WDM Transmission Systems Electronic Precompensation Intrachannel Nonlinearities
2015/7/17
A simple criterion is presented which describes the impact of interchannel nonlinearities in wavelength-division multiplexing systems with electronic precompensation of intrachannel nonlinearities. Fu...
Improvement of tolerance to fibre non-linearity of incoherent multilevel signalling for WDM transmission with 10-Gbit/s OOK channels
non-linearity incoherent multilevel signalling WDM transmission 10-Gbit/s OOK channels
2015/7/16
Fibre nonlinear effect on incoherent multilevel signalling with co-propagating 10-G OOK channels is investigated by experiments and numerical simulations, and QAM signals with non-Euclidean decision b...
