    摘要： A lens array (38) is mounted on the front surface of an optical fiber array (32) holding optical fibers (35, 36) for input and emission. The lens array (38) includes: an input lens (40a) for converting a signal light (45) emitted from the optical fiber (35) into parallel light or converged light; and an output lens (40b) for converging the returned parallel light and connecting it to the optical fiber (36). A rectangular prism (34) having a form of a rectangular equilateral triangle is arranged in front of the optical fiber array (32) having the lens array (38). The signal light (45) emitted from the optical fiber (35) is totally reflected twice by the rectangular prism (34) and comes into the optical fiber (36). A transparent rectangular rotary block (33) is arranged between the lens array (38) and the rectangular prism (34). The outgoing signal light (45) and the returning signal light (45) have optical axis shifted by the rotary block (33) where the signal light passes. With this structure, it is possible to obtain a small-size variable light attenuator having a high control accuracy of the attenuation quantity of the signal light and a high resolution.

    摘要： To decrease an insertion loss by shortening an optical path length between an input side optical fiber and an output side optical fiber, and to decrease a stroke of a drive component. Input side optical fibers and a preliminary optical fiber arranged in parallel to one another and output side optical fibers arranged in parallel to one another are arranged in two stages, and a fixed prism 14 is arranged to be opposite to end surfaces of these. A preliminary optical fiber prism 15b is provided on one oblique surface of the fixed prism 14 to be opposite to a preliminary optical fiber 20, and a driven prism 15a can be made to come in contact with and separated from the one oblique surface of the fixed prism 14, and the driven prism 15a can be moved along the input side optical fibers. At a position where the driven prism 15a comes in contact with the oblique surface of the fixed prism 14, outgoing light from the input side optical fiber is not totally reflected at the oblique surface of the fixed prism 14, but is incident on the driven prism 15a, and after it is sent from the driven prism 15a to the preliminary optical fiber prism 15b, it is incident on the preliminary optical fiber 20 from the preliminary optical fiber prism 15b.
