Title:
OPTICAL FIBER CUTTING DEVICE AND METHOD OF CUTTING OPTICAL FIBER
Document Type and Number:
WIPO Patent Application WO/2022/244868
Kind Code:
A1
Abstract:
An optical fiber cutting device of the invention includes a pair of grippers configured to grip an optical fiber having a glass portion, a gripping force applier configured to change a gripping force, a tension applier configured to apply tension to the optical fiber, a tension measuring sensor configured to measure the tension, a controller configured to control the gripping force, and a blade forming a scratch on the optical fiber. The controller determines a set gripping force on the basis of a minimum non-slip gripping force in a state in which a predetermined tension is applied to the optical fiber. In a state in which at least one of the pair of grippers grips the optical fiber with the set gripping force, the optical fiber is cut by applying tension to the optical fiber, and a scratch is formed on the optical fiber by the blade.
