摘要： An optical fiber switch for switching N.times.2N (N.gtoreq.1) circuits is capable of mechanically switching a plurality of pairs of optical fiber circuits at the same time. The optical fiber switch moves an N (N.gtoreq.1) number of movable optical fibers at the same time by a drive member which is guided by a slit of alignment members and reciprocated at right angles or in the X direction with respect to an optical axis. The optical axes of the movable optical fibers are accurately aligned with the optical axes of first or second fixed optical fibers by a mechanism which presses the N (N.gtoreq.1) number of the movable optical fibers against alignment V grooves at the same time by utilizing the flexure stress of an elastic pin provided on an actuator. Further, the elastic pin imparts a self-holding function to the actuator.

摘要： To connect one ribbon-shaped optical fiber cord to an opponent ribbon-shaped optical fiber cord while making reliable optical connection therebetween, an optical fiber splicer is used. The optical fiber splicer includes as essential components an aligning member and a cover member, and the cover member is fitted into the aligning member to build an integral structure without an optical fiber using an adhesive. In practical use, after the adhesive is hardened, both the ribbon-shaped optical fiber cords are inserted into the integral structure from both sides of the optical fiber splicer so that sheathless optical fibers of both ribbon-shaped optical fiber cords are firmly received in V-shaped aligning grooves on the aligning member in a face to-face relationship. When the optical fiber splicer is used as connector plugs for an optical connector, sheathless optical fibers of both ribbon-shaped optical fiber cords are integrally connected to each other by employing an electrical charging process, and thereafter, the sheathless optical fibers are received in the V-shaped aligning grooves of the aligning member. Subsequently, the cover member is fitted into the aligning member using an adhesive to build an optical fiber splicer which in turn is cut into two segments, i.e., a first connector plug and a second connector plug both of which can be used as essential components for an optical connector in a suitable manner.

摘要： An optical attenuator comprising an optical fiber and at least a light attenuating portion disposed on the optical fiber. The light attenuating portion is formed such that a part of the optical fiber is heated by an opposing pair of discharge electrodes or gas burners and then compressed in the axial direction to provide a spherically contoured light attenuating portion or pulled in the axial direction to provide a light attenuating portion having a reduced diameter. In addition, a method and an apparatus for producing an optical fiber of the foregoing type are disclosed. The method is practiced by way of the steps of heating a part of an optical fiber and then physically deforming the heated part to serve as a light attenuating portion by compressing or pulling it in the axial direction. The apparatus includes as essential components a stationary clamp jig, and a movable clamp jig arranged opposite to the stationary clamp jig and an opposing pair of discharge electrodes or gas burners for heating a part of the optical fiber. The movable clamp jig is displaced toward or away from the stationary clamp jig by rotationally actuating a micrometer.

摘要： A new type of optical power attenuator of the variable attenuation type. The optical connector ferrule edges are finished by polishing them at an inclination angle of seven to 12 degrees with respect to the optical axis thereof, and both ferrule edges face each other with a gap therebetween. One of the ferrule edges is fastened not so that it can be rotated whereas the other can be rotated around its optical axis. The attenuation is determined by both the inclination and gap, and it can be set stably by adjustment of the angle of the rotation around the optical axis of the ferrules.
