TL;DR: The most recent advanced concepts and methods employed in the cutting-edge spectrally efficient coherent fiber-optic transoceanic transmission systems, such as probabilistic shaping, adaptive digital nonlinear compensation, rate-adaptive spatially coupled low-density parity check codes, and dual-band C+L-band transmission are reviewed.

TL;DR: This work demonstrates the first 115Tb/s lumped amplified transmission system based on novel ultrawideband semiconductor optical amplifiers and shows the successful transmission of 250 channels carrying >400Gb/s each over a 100-km transmission link.

TL;DR: In this paper, a general theory of nonlinear interactions between signal and amplified spontaneous emission noise in wavelength division multiplexed fiber-optic coherent transmission systems is presented, based on the regular perturbation treatment of the nonlinear Schrodinger equation, which governs the wave propagation in the optical fiber, and is exact up to the first order in the fiber nonlinear coefficient.

TL;DR: In this article, the authors demonstrate the transmission of the same throughput over multimode fiber using a low-cost Electroabsorption modulated laser (EML) instead of an external MZM.

TL;DR: In this article, the transmission of 155 channels modulated with PDM16QAM over 6,600 km of pure silica core fiber was demonstrated using C and L bands with hybrid EDFA/Raman amplification.
