Abstract: A utility pole degradation detection system according to the present disclosure includes: a sensing optical fiber (10) laid on a plurality of utility poles (30); a receiving unit (201) that receives vibration information detected by the sensing optical fiber (10); an identifying unit (202) that identifies a natural frequency of each of the plurality of utility poles (30) on the basis of the vibration information; and an analyzing unit (203) that analyzes a degradation state of at least one utility pole (30) among the plurality of utility poles (30) on the basis of a natural frequency of each of the plurality of utility poles (30).
