In a single-channel high power transmission experiment, no nonlinearity penalty was observed for up to 1 W of received power, despite the very low chromatic dispersion of the fiber ({\ensuremath{<}}2 ps/nm/km). Our simulations show that such a low level of nonlinearity should enable transmission at 6.4 Tb/s over 1200 km of HC-ARF, even when the fiber attenuation is significantly greater than that of SMF-28. As signals propagate through hollow-core fibers at close to the speed of light in vacuum such a link would be of interest in latency-sensitive data transmission applications.}, author = {Liu, Z and Karanov, B and Galdino, L and Hayes, J and Lavery, D and Clark, K and Shi, K and Elson, D and Thomsen, B and Petrovich, M and Richardson, D and Poletti, F and Slavik, R and Bayvel, P}, url = {https://doi.org/10.1109/JLT.2018.2883541} }
