Abstract
A fiber cutter includes: a base including a fiber grip that grips an optical fiber; a slider including a fiber end grip that grips an end portion of the optical fiber, wherein the slider moves relative to the base; a cut former including a blade forming an initial cut in the optical fiber and disposed between the fiber grip and the fiber end grip; and a spring that applies a force between the base and the slider to apply a tension to the optical fiber gripped by the fiber grip and the fiber end grip, wherein the cut former is disposed on the slide, and when the initial cut grows and the optical fiber cleaves, the cut former moves together with the slider by the force of the spring.
