Advanced Modulation Techniques for Flexible Optical Transceivers: The Rate/Reach Tradeoff
Full text linkThis tutorial paper reviews advanced modulation techniques that have been proposed in the literature for the implementation of flexible (or reconfigurable) transceivers, which are fundamental building blocks of next-generation software-defined optical networks. Using a common reference multi-span propagation system scenario, the performance of transceivers employing standard quadrature amplitude modulation with variable-rate forward error correction, probabilistic constellation-shaping, and time-domain hybrid formats is assessed, highlighting the achievable flexibility in terms of continuous tradeoff between transmission rate and distance. The combination of these techniques with sub-carrier multiplexing, which enables an increase of the fiber nonlinearity tolerance thanks to the optimization of the symbol rate per sub-carrier, is also discussed
Modeling and mitigation of nonlinear effects in uncompensated coherent optical transmission systems
No full textWe review recent results on analytical modeling of non-linear interference in multispan optical systems with high-order modulation and coherent detection, and on performance gains that can be achieved through non-linearity mitigation in digital coherent receivers
