Abstract

An optical fiber cutting system according to this disclosure includes a pair of clamps disposed at an interval in a longitudinal direction of an optical fiber, the pair of clamps being configured to grip the optical fiber; a disk-shaped blade member including an outer peripheral edge portion, the blade member being configured to scratch 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, the blade member being capable of changing a position of the outer peripheral edge portion where the outer peripheral edge portion is in contact with the optical fiber; a pressing member configured to cut the optical fiber by pressing and bending a scratched portion on the optical fiber; and an acquisition unit configured to acquire position information of the outer peripheral edge portion where the outer peripheral edge portion is in contact with the optical fiber. The acquisition unit is a sensor configured to acquire the position information of the outer peripheral edge portion by detecting a direction of a magnetic line corresponding to the position of the outer peripheral edge portion.

Description

technical field [0001] The present invention relates to optical fiber cutting systems. Background technique [0002] When cutting an optical fiber (optical fiber core), first, a knife member is brought into contact with the optical fiber to give an initial flaw on the surface of the optical fiber. Then, the optical fiber is severed by bending the portion of the optical fiber with the initial flaw. The knife part wears out each time an initial scar is applied to the fiber. Therefore, conventionally, it has been considered to change the portion of the blade member that is in contact with the optical fiber (for example, refer to Patent Documents 1 to 3). [0003] Patent Document 1 discloses that a disc-shaped knife member (scarring knife) rotates the knife member a little every time an initial flaw is applied to an optical fiber. [0004] Patent Document 2 discloses that the end face of the cut optical fiber is analyzed by an image analysis device, and when it is determined ...
