Ultrahigh-speed video recording of fiber-fuse ignition was reported for
the first time. Fiber fuse was initiated in a glass ferrule in which
the fiber end was in contact with cobalt oxide powder. Optical
discharge emerged from a slowly moving darker radiant at about 300$\mu$m
distance from the fiber end. Absence of void in the trajectory of the
dark radiant implies that there is no glass-plasma interface at the
radiant. Two other types of fused damage on ignition were also reported.
