Abstract

Noise accumulation is one of the limitations of amplified transoceanic links.1 Concerning this topic, we reported that a key amplifier feature is its spectral gain shape: if the signal is located at the gain peak, satisfactory signal-to-noise ratios are obtained for distances over 10 000 km with no need for additional in-line optical filters.2 This possibility has recently been demonstrated in a straight-line 9000-km transmission experiment.3
