Abstract
An optical fiber cutting device is proposed which can perform cutting of optical fibers on the principle of stress rupture stably under predetermined conditions, and which eliminates damage to the blade or the cut end face due to failure or excessive movement. When a wire of an optical fiber stopped by a ferrule-holding portion is gripped by a chuck of a fiber-holding portion and a lever is pulled in this state, tension corresponding to the amount of relative movement of the lever is applied to the optical fiber. Further, this relative movement is converted to the motion of a cutting blade table by a motion-converting mechanism to control the position of a blade. While no tension is applied to the optical fiber, the fiber-holding portion moves following the movement of the lever.
