Abstract
An optical fiber cutter for cutting an optical fiber wire according to the principle of the stress-rupture includes a tension applying mechanism and a movable blade. The tension applying mechanism applies tension to the optical fiber wire in an axial direction thereof. The movable blade is contactable with the optical fiber wire in a direction perpendicular to the axial direction so as to impart an initial crack to the optical fiber wire to which the tension is applied. The movable blade contacts the optical fiber wire in only one direction, which is perpendicular to the axial direction.
