Spectral Efficiency Optimization in Flexi-Grid Long-Haul Optical Systems
Tommaso Foggi, Giulio Colavolpe, Alberto Bononi +1
Flexible grid optical networks allow a better exploitation of fiber capacity, by enabling a denser frequency allocation. A tighter channel spacing, however, requires narrower filte…
Optical Time-Frequency Packing: Principles, Design, Implementation, and Experimental Demonstration
Marco Secondini, Tommaso Foggi, Francesco Fresi +7
Time-frequency packing (TFP) transmission provides the highest achievable spectral efficiency with a constrained symbol alphabet and detector complexity. In this work, the applicat…
Time-Frequency Packing for High Capacity Coherent Optical Links
Giulio Colavolpe, Tommaso Foggi
We consider realistic long-haul optical links, with linear and nonlinear impairments, and investigate the application of time-frequency packing with low-order constellations as a p…
