Two-Dimensional Constellation Shaping in Fiber-Optic Communications

Zhen Qu    
Ivan B. Djordjevic and Jon Anderson    

Resumen

Constellation shaping has been widely used in optical communication systems. We review recent advances in two-dimensional constellation shaping technologies for fiber-optic communications. The system architectures that are discussed include probabilistic shaping, geometric shaping, and hybrid probabilistic-geometric shaping solutions. The performances of the three shaping schemes are also evaluated for Gaussian-noise-limited channels.
