Hollow-Core Fiber (HCF) is an optical fiber that transmits light through an air-filled central core instead of a solid glass core. This design significantly reduces the interaction between the light and the material, leading to lower transmission losses and reduced distortion from nonlinear effects.

First Field Demonstration of Hollow-Core Fibre Supporting Distributed Acoustic Sensing and DWDM Transmission

We demonstrate a method for measuring the backscatter coefficient of hollow-core fibre (HCF), and show the feasibility of distributed acoustic sensing (DAS) with simultaneous 9.6-Tb/s DWDM transmission over a 1.6-km field-deployed HCF cable.
