Abstract
An optical fiber clamp, having a plurality of V-shaped grooves, stores coated optical fibers in the respective V-shaped grooves. The coated optical fibers are held by a pressing force of the clamp. A cushion portion, having an abrasion-resistant smooth film layer, is provided on the side of an optical fiber pressing surface of the clamp. The cushion portion applies a constant pressure to the optical fibers through the abrasion-resistant smooth film layer and absorbs any differences in the outer diameters and other dimensional peculiarities of the optical fibers. Thus, the optical fibers in the V-shaped grooves can be arranged and held uniformly, so that a batch fusion and connection can be performed on a multicore fiber with a minimum loss of connection. The optical fiber clamp minimizes axial displacements of respective optical fibers.
