Using time-adaptive probabilistic shaped 64QAM driven by a simple SNR prediction algorithm, we demonstrate $>$450 Gbps transmission over a 55-m free-space optics link with enhanced resilience towards rainy weather conditions. Through continuous measurement over 3-hours, we demonstrate $sim$40~Gbps average bit-rate gain over unsupervised fixed modulation.

We provide a new analytical model that fully justifies the recently disclosed Generalized Droop Formula of the nonlinear signal-to-noise (SNR) ratio in very-long submarine links with power-mode amplifiers, and show its relation with the Gaussian-Noise model SNR.

Experimental Stokes vector spectroscopy characterizes polarization state noise in nonlinear fiber transmission. Noise bandwidths of a few MHz are observed from XPM-blurred receive SOPs using a polarization scrambling interferometer. This method can detect data pattern correlations among WDM channels that contribute to performance degradations in signalling.

A novel tool, based on Bayesian filtering framework and expectation maximization algorithm, is numerically and experimentally demonstrated for accurate frequency comb noise characterization. The tool is statistically optimum in a mean-square-error-sense, works at wide range of SNRs and offers more accurate noise estimation compared to conventional methods.

We propose a quality-of-transmission (QoT) aware heuristic algorithm for the placement of amplifiers in elastic metroaggregation networks with the objective of minimizing their number while guaranteeing lightpaths’ QoT. Results show that optimized amplifier placement can lead to significant reduction of amplifiers with respect to baseline approaches.
