Abstract
A method is presented for remotely identifying a utility pole position and estimating a state of an overhead optical fiber cable. The method includes identifying a boundary region of a vibration distribution as a utility pole position, from a vibration distribution pattern obtained by measuring strain amounts with respect to distances of an optical fiber by an optical fiber vibration distribution measuring method at each time and sequentially stacking the strain amounts.
