OPTICAL-FIBER SHORT INSTANTANEOUS INTERRUPTION SWITCHING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a short instantaneous interruption switching device in which a positional deviation hardly occurs when an optical fiber is bent, in a short instantaneous interruption switching operation of the optical fiber.SOLUTION: The switching device includes: bending units 31 and 32 that move in a bending direction crossing the arrangement direction of an optical fiber and bend the optical fiber; and a pressing member (clamp guide) for pressing the optical fiber in a pressing direction that crosses the arrangement direction of the optical fiber and crosses the bending direction, when the bending units bend the optical fiber.SELECTED DRAWING: Figure 3
