Fig. 3: Loss and chromatic dispersion comparison with state-of-the-art telecoms fibres.

a, Loss of the DNANF in this work, compared with that of the record low-loss PSCFs from 2002 (Nagayama et al.³⁴) and 2025 (Sato et al.¹⁰). b, Simulated dispersion of the DNANF and measured dispersion of the PSCF from Sato et al.
