Hollow-core photonic crystal fibres have excited interest as potential ultra-low loss telecommunications fibres because light propagates mainly in air instead of solid glass. We propose that the ultimate limit to the attenuation of such fibres is determined by surface roughness due to frozenin capillary waves. This is confirmed by measurements of the surface roughness in a HC-PCF, the angular distribution of the power scattered out of the core, and the wavelength dependence of the minimum loss of fibres drawn to different scales.

Survey and Evaluation of Space Division Multiplexing: From Technologies to Optical Networks (2015, background): “The fact that nearly 90% of the light propagates through air, offers ultra-low latency (almost 30% reduction from SMF) and enormous decrease in non-linear effects, potential for extra-low loss, while at the same time supports several LP modes [51], the number of which depends on the fibers dimension”
