摘要： .theta.-clamp also serves as a jacket clamp. The clamp comprises a cover mounted on an arm by a hinge and kept closed by a magnet, so that a pusher provided in the cover is urged against a jacketed portion of an optical fiber by a spring. In this state, the fiber is rotated in a .theta. direction by rotating a dial. .theta.-clamp also serves as a jacket clamp. Therefore, 1. The .theta.-clamp can be positioned close to a fiber clamp. For this reason, the optical fiber is not twisted during .theta.-axes alignment, and a follow-up property of rotation of the optical fiber with respect to rotation of the .theta. axis is improved. In addition, the apparatus need not be adjusted so as not to twist the optical fiber. 2. The distance between fiber clamp and .theta.-clamp is shortened. Therefore, when the optical fiber is clamped and moved in the z direction, the jacketed portion is not flexed. For this reason, a follow-up property of movement of the end face of the optical fiber with respect to movement of a table in the z-axis direction is improved.

摘要： An apparatus for aligning a plurality of single-fiber cables, comprises a base, a cover hinged to the base and forming a gap along with the base when closed, and a pair of arms inserted in the gap and movable within the gap, for aligning the single-fiber cables in the same plane. To align single-fiber cables by means of the apparatus, the cables are arranged on the base, one after another. Then, the cover is closed, whereby the cables are located in the gap between the base and the cover. The arms or the pawl members, which are inserted in the gap, are moved, thereby putting the cables together and placing them parallel to one another in the same plane, any cable not forced above so that it rides atop another. The cables, thus aligned, can easily be held by a holder designed for multi-fiber cables.

摘要： The present invention discloses an optical fiber fusion splicer which, together with fusing and splicing optical fibers in the state in which the jacket of each optical fiber core is clamped by being provided with a means by which a V-shaped groove base is moved up and down so that the axial centers of optical fiber cores are positioned at the proper position for electrical discharge, is provided with a mechanism that temporarily moves clamp upward and V-shaped groove base downward followed by re-clamping in order to eliminate a lift-up phenomenon during rotation alignment of the constant polarization optical fibers.
