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 (<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. %A Z Liu %A B Karanov %A L Galdino %A J Hayes %A D Lavery %A K Clark %A K Shi %A D Elson %A B Thomsen %A M Petrovich %A D Richardson %A F Poletti %A R Slavik %A P Bayvel %I Institute of Electrical and Electronics Engineers
