The Prospects of Hollowcore Fibres with Lower Attenuation Than Single-Mode Fibre

Nested Anti-Resonant Nodeless Fibre (NANF
^®
) technology is achieving record attenuation values for hollowcore, near parity with single-mode fibre. We report the development of hollowcore capable of realising latency saving far beyond other cable types and the potential to redefine the capabilities of future optical networks.
