Problems solved by technology

[0010] However, because the knife components used to cut the fiber are very expensive, it is desirable to be able to use the entire portion of the knife component that applies the initial damage to the fiber without wasting
However, in the above-mentioned conventional structure, when changing the position of the knife member, there is a case where a movement error of the knife member occurs.
As a result, there is a problem that part of the knife part is not used

Abstract

An optical fiber cutting system includes a pair of clamps disposed at an interval in a longitudinal direction of an optical fiber and that grasps the optical fiber; a disk-shaped blade member that passes between the pair of clamps, causes an outer circumferential edge to come into contact with the optical fiber, and scratches a surface of the optical fiber, where a position of the outer circumferential edge which is to be in contact with the optical fiber is changeable; a pressing member that press-bends a scratched portion of the optical fiber and cuts the optical fiber, and an acquirer that acquires position information of the outer circumferential edge which is to be in contact with the optical fiber.

Description

technical field [0001] The present invention relates to optical fiber cutting systems. [0002] This application claims priority based on Japanese Patent Application No. 2016-214849 filed in Japan on November 2, 2016, and uses the entire content here. Background technique [0003] When cutting an optical fiber (optical fiber core), first, a knife member is brought into contact with the optical fiber to apply initial damage to the surface of the optical fiber. Thereafter, the optical fiber is cut by bending the portion of the optical fiber where the initial damage was applied. The knife member wears down each time an initial damage is applied to the optical fiber. Therefore, conventionally, it has been considered to change the portion of the blade member that contacts the optical fiber (for example, refer to Patent Documents 1 to 3). [0004] Patent Document 1 discloses that the blade member is slightly rotated every time an initial damage is applied to an optical fiber wi...
