Abstract

PURPOSE:To maintain excellent matching precision and to simplify the operation by opposing end surfaces of a couple of optical fibers to each other all the time by an elastic body, and by excluding a light transmission line by deforming the elastic body by pressure. CONSTITUTION:A couple of optical fibers 1 are arranged opposing to each other at any time by elastic body 5. At need, liqud 6 with a refractive index greater than that of elastic body 5 and equal to that of a core part is sealed in and elastic body 5 is pressurized by pressurizing mechanism 7 to close the part of liquid 6. Consequently, light transmitted via optical fibers 1 and liquid 6 is occluded. When liquid 6 is not sealed in, one end of elastic body 5 is displaced via displacing mechanism 8 to cut off the transmitted light. As the pressure is releaved, elastic body 5 is restored, so that while the excellent matching precision is maintained, the operation is simplified.
