【 摘 要 】

References(8)We investigated the dynamics of fiber fuse propagation with a long-period damage track and its power dependence in hole-assisted fiber. When the input power is high, the fiber fuse velocity changes greatly over the propagation distance. However, when the input power is low, the velocity change is small and the fiber fuse propagates in almost the same way as in a conventional single-mode fiber. We found that the fiber fuse propagation becomes unstable when the input power exceeds 4.7W at a wavelength of 1550nm.
