摘要： A device for splicing multiple optical fibers includes a novel splice element having two plates formed from a sheet of malleable material, there being a fold line in the sheet forming a hinge, the two plates being folded toward one another to define opposing surfaces. One of the opposing surfaces has several fiber receiving grooves therein, parallel with the fold line, and the other surface has ramps at each end to support the fibers proximate the transition from their buffered portions to their stripped portions. The ramps are adjacent porches which are integrally formed with one of the plates, the porches having additional grooves for aligning the fibers with the fiber receiving grooves. Stop pads are provided on both opposing surfaces, at the corners of the plates, to insure a clearance space at the ends of the plates which provides for more gradual clamping of the fibers, reducing insertion loss.

摘要： An optical fiber splice element comprising a sheet of ductile material having a novel focus hinge defining first and second legs, each of the legs having a V-groove therein for receiving the optical fibers. The focus hinge, comprising a groove on one side of the sheet, a notch on the other side of the sheet aligned with the groove, and a convex hinge web, provides precise registration of the V-grooves when the sheet is folded; this in turn leads to improved alignment of the fibers. The V-grooves also have a novel angular geometry which optimizes the clamping forces, resulting in lower insertion loss. The interior angle of the V-grooves is smaller than the optimum angle whereby, when the fiber is clamped and portions of the V-groove surfaces are deformed, the V-groove has an effective angle which is approximately equal to the optimum angle.

摘要： A tool for actuating an optical fiber splice having an actuation element which moves longitudinally within the splice. The tool includes a base having a recess for receiving the splice, and two channels parallel to and aligned with the recess. A pair of fiber holders are used to manipulate the fibers, the holders being placed in the channels. The channels have ramped surfaces inclined toward the recess to facilitate proper insertion of the fibers into the splice, and the ramped surfaces have slots therein allowing passage of push rods which bias the holders toward the splice, providing positive abutment of the fiber end faces within the splice. Backstops are formed at the outside ends of the channels, and sidewalls are formed adjacent the backstops. A lever is pivotally attached to the underside of the base, and has an actuation stud which passes through an opening in the base and contacts the actuation element of the splice. When the lever is moved from an unactuated position to an actuated position, the stud forces the actuation element of the splice to clamp the inserted fibers. Means may be provided to retract the push rods, and a magnifying glass is provided to facilitate visual inspection of the inserted fibers.

摘要： A device for splicing multiple optical fibers includes a splice element having means for holding the optical fibers, a splice body having a slot containing the splice element, and extensions on either end of the splice body for supporting a portion of the fibers. Each of the extensions has an end cover positionable in open and closed positions which provides protection to the fibers against environmental influences. The end covers may advantageously include collapsible compartments filled with a sealant material whereby, when the covers are moved to the closed positions, the sealant material is channeled towards the slot containing the splice element.

摘要： An optical fiber splice comprising a hinged splice element having two legs, at least oen of the legs having a groove therein for h olding the fibers to be spliced, a base for receiving the splice element, and a cap fitting over the base which has camming bars extending into the base and around the splice element, the camming bars urging the legs into a closed, clamping state. The camming bars are shorter than the splice element, applying the clamping force only to the center thereof, which allows the legs to flex open at their ends and apply a gradual clamping to the fibers. Alternatively, the camping bars may be thicker at their center and have inwardly facing surfaces which are convex, providing gradual clamping of the fibers which minimizes insertion losses due to microbending. The cap is provided with tabs which hold the cap in open and closed positions, the open positon allowing insertion of the fibers into the splice elements, and the closed position causing the convex surfaces of the camming bars to forcibly contact the legs of the element and thereby clamp the fibers.

摘要： An optical fiber splice comprising a hinged splice element having two legs, at least one of the legs having a groove therein for holding the fibers to be spliced, and an index matching gel disposed between the legs. In the embodiment wherein the legs remain divergent or slightly open in the clamping state, a vent hole is punched in the center of the splice element to minimize migration of the gel between the inner and outer surfaces of the elements near the fiber interface, which could otherwise increaase insertion loss due to the migration of microbubbles, particularly during temperature cycling. A vent channel may optionally be formed in the splice element to provide fluid communication between the groove and the vent hole. In the embodiment wherein the legs are essentially parallel and in intimate contact in the clamping state, rails may be provided in one leg opposite leg with the groove whereby the rails impinge on either side of the groove and block the flow of the index matching gel.
