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

Abstract

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.

arXiv commentFollow-up document to a European Conference on Optical Communications (ECOC) 2025 paper. In this version we add the analysis of Rayleigh backscattering. This new manuscript will be submitted to IEEE Photonics Technology Letters. This version corrects a typo in the one of the Appendix formulas shown in the previous version. No impact on results
