For the first time, we successfully demonstrate the transmission of commercial 10- and 100-Gb/s interfaces, both direct detect and coherent, over 2.75 km of hollow-core fiber. The fiber is connected to the transceivers using spliced standard single-mode pigtails. This demonstration solidifies the commercial potential for low latency applications.
