Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1 . A method for estimating a state of an overhead optical fiber cable, the method comprising: determining that a ground obstacle is in contact with an optical fiber cable on condition of vibration stopped or reduced in the middle of an optical fiber, from a vibration distribution pattern obtained by measuring strain amounts with respect to optical fiber distances in a utility pole span by an optical fiber vibration distribution measuring method at each time and sequentially stacking the strain amounts.
