We study the transmission of light through different lengths of Hollow-core bandgap fiber. We demonstrate 95% transmission of 5 picosecond pulses at 1064nm through fiber lengths of 1m, but only 77% transmission through longer lengths of 10m. This variation is not consistent with the measured attenuation of the "fundamental" low-loss mode of the fiber as being below 20dB/km in this spectral range, because the light transmitted through the short fiber not exclusively in the fundamental fiber mode. We conclude that great care is required to understand coupling efficiencies using short fiber lengths.
