Optical fiber cutting system

An optical fiber cutting system comprising:

• a pair of clamps disposed at an interval in a longitudinal direction of an optical fiber and that grips the optical fiber;
• a disk-shaped blade member including an outer peripheral edge portion, wherein the blade member:
• scratches the optical fiber by moving between the pair of clamps and by bringing the outer peripheral edge portion into contact with a surface of the optical fiber, and
• changes a position of the outer peripheral edge portion where the outer peripheral edge portion is in contact with the optical fiber;
• a pressing member that breaks the optical fiber by pressing and bending a scratched portion on the optical fiber;
• and
• a sensor that acquires position information of the outer peripheral edge portion where the outer peripheral edge portion is in contact with the optical fiber,
• wherein the sensor acquires the position information of the outer peripheral edge portion by detecting a direction of a magnetic line that corresponds to the position of the outer peripheral edge portion.
