I/We Claim:
1. An optical fiber cutting system comprising:
a pair of clamps disposed at an interval in a longitudinal direction of an optical fiber and configured to grasp the optical fiber;
a disk-shaped blade member configured to move so as to pass between the pair of clamps, cause an outer circumferential edge to come into contact with the optical fiber, and thereby scratch a surface of the optical fiber, wherein a position of the outer circumferential edge which is to be in contact with the optical fiber is changeable;
a pressing member configured to press-bend a scratched portion of the optical fiber and thereby cut the optical fiber; and
an acquirer configured to acquire position information of the outer circumferential edge which is to be in contact with the optical fiber.
2. The optical fiber cutting system according to claim 1, wherein
the acquirer includes an outer edge position measuring sensor configured to measure a rotation angle of the blade member as the position information to be acquired.
3. The optical fiber cutting system according to claim 1 or 2, wherein
the blade member is configured to move in a direction perpendicular to the longitudinal direction,
a relative position between the optical fiber and the outer circumferential edge in a height direction perpendicular to a movement direction of the blade member and the longitudinal direction of the optical fiber is changeable, and wherein
the acquirer is configured to further acquire information on the relative position

between the optical fiber and the outer circumferential edge in the height direction.
4. The optical fiber cutting system according to claim 3, wherein
the acquirer further includes a position measuring sensor configured to measure a position of the outer circumferential edge in the height direction as the information on the relative position.
5. The optical fiber cutting system according to any one of claims 1 to 4, further
comprising:
a calculator configured to calculate maintenance information on the blade member according to the position information acquired by the acquirer.
6. The optical fiber cutting system according to claim 5, further comprising:
a storage configured to store at least one of the position information and the maintenance information.
7. The optical fiber cutting system according to claim 5 or 6, further comprising:
a display configured to display at least one of the position information and the
maintenance information.
8. The optical fiber cutting system according to any one of claims 5 to 7, further
comprising:
a transmitter configured to transmit at least one of the position information and the maintenance information, from an optical fiber cutter to an external device which is separate from the optical fiber cutter, the optical fiber cutter including the pair of clamps,

the blade member, the pressing member, and the acquirer.
9. The optical fiber cutting system according to claim 8, wherein
the calculator is provided in the external device, and
the maintenance information calculated in the calculator of the external device is transmitted to the optical fiber cutter and is stored in a storage provided in the optical fiber cutter.
10. The optical fiber cutting system according to claim 8 or 9, wherein
the calculator is provided in the external device, and
the maintenance information calculated in the calculator of the external device is transmitted to the optical fiber cutter and is displayed on a display provided in the optical fiber cutter.
11. The optical fiber cutting system according to claim 8, wherein
at least one of the position information and the maintenance information is associated with connection data to be collected by a fusion splicer that is configured to connect the optical fibers to each other and is stored in a storage provided in the external device.
