We propose a passive optical network (PON) solution to reach 32 Gb/s over a traditional high loss downstream splitter-based optical distribution network without using multiple wavelengths at the optical line terminal (OLT) side nor massive digital si

Noise due to nonlinear effects in uncompensated links has recently been shown to be Gaussian and additive. We experimentally investigate the law governing its accumulation. Our results suggest a mild super-linear accumulation versus number of spans,

We demonstrate that the traffic capacity of legacy DWDM reconfigurable networks can be boosted thanks to the Nyquist-WDM technique and PM-64QAM modulation format. To this end, dual carrier and single carrier channels with raw transmission bit rate sp

We report on a comprehensive performance comparison of seven different fiber types: transmission experiments based on of Nyquist-WDM using PM-16QAM modulation over uncompensated links show a perfect agreement with GN model prediction.

Ultra-Long-Haul Transmission of 16×112 Gb/s Spectrally-Engineered DAC-Generated Nyquist-WDM PM-16QAM Channels with 1.05×(Symbol-Rate) Frequency Spacing

Using serial-transmission 112Gb/s PM-16QAM we achieved net SE 7.12 and 6.32 b/s/Hz, and SE(x)distance 13,949 and 23,396 b/s/Hz·km, for 7% and 20.5% FEC overhead, respectively, by means of DAC-enabled spectral engineering, over high-performance PSCF.
