Fluxon-propagation threshold properties in a resistively coupled Josephson transmission line are experimentally investigated by use of a direct measurement system for a single fluxon observation. A nontransmission bias-current region is observed between the high- and low-bias-current transmission regions. These unexpected threshold properties can be interpreted in terms of an interaction among damping oscillations. Experimentally obtained properties approximately agree with numerical simulations.
