Patent ID: 8196793

Claim:
An optical fiber cutting apparatus comprising: a clamp configured to hold a coated optical fiber, including a glass fiber and a coating, on both sides of a portion-to-be-cut of the coated optical fiber; a disk-shaped blade member configured to move at the portion-to-be-cut in a direction orthogonal to an axis of the optical fiber to cut the coating and to provide a slit into the glass fiber; and a support configured: to press the portion-to-be-cut from an opposite side of the blade member with respect to the portion-to-be-cut during cutting the coating and providing the slit into the glass fiber so as to clamp the optical fiber with a shorter clamping interval than the clamp, and to further press the portion-to-he-cut after cutting the coating and providing the slit into the glass fiber so as to cut off the optical fiber at the portion-to-be-cut using the pressing of only the support, wherein a head of the support is formed with a groove along the direction in which the blade member moves.
