The Case for a DNANF 1Pb/s Trans-Atlantic Submarine Cable

The recent progress in low-loss hollow-core fibers allows to speculate on the possibility of building a transatlantic submarine cable that can achieve the goal of 1 Pb/s per direction, leveraging bidirectional transmission, and at the same time drastically increase span length, theoretically to 200km. In this version, we add the analysis of the impact of Rayleigh backscattering.
