Abstract
An optical fiber measurement device includes a light source, a light detector, a direction-changing member, and a tension-applying member. The light source emits light toward an optical fiber. The light detector receives the light that has propagated through the optical fiber. The optical fiber is hung on the direction-changing member. The direction-changing member changes an extending direction of the optical fiber to extend downward, the optical fiber being optically connected to the light source and the light detector at each of two end parts of the optical fiber. The tension-applying member applies a tension to the optical fiber hanging from the direction-changing member.
