Abstract: A recoating splice sleeve is provided to protect fused or jointed optical fibers, at and adjacent their point of fusion, against environmental damage and to restore adequate strength at the splice after the fusion. The recoating splice sleeve includes an inner tube, and an outer tube having a portion with diminished structure integrity such that the portion is easily broken to facilitate removal of the outer tube. The inner tube is made of a fiber recoating material. The splice sleeve is positioned over the point of fusion of the fibers. The splice sleeve, together with the fused optical fibers, are heated in order to melt the fiber recoating material around the fused fibers. Once the fiber recoating material of the inner tube has cured around the fused fibers, the outer tube is separated along a tube separation assist feature such as a portion having diminished structural integrity, removed and discarded.

Abstract: A splice sleeve to protect fused or jointed optical fibers at and adjacent their point of fusion against environmental damage and to restore adequate strength by creating a suitable reinforcement at the splice after the fusion. The splice sleeve preferably includes an inner tube, a strengthening rod, an outer tube, and an activatable heat source including one or more substances. Preferably, the strengthening rod and the heat source are disposed between inner tube and outer tube. In use, the splice sleeve is positioned over the point of fusion of the fibers. The substances are exposed to each other, preferably inside of the heat shrinkable tube. This produces a chemical reaction that gives off heat sufficient to affix the splice sleeve to the fused fibers and reinforce the fibers at their point of fusion.

Abstract: An optical fiber cleaver with a traversing mechanism and measuring device to impart relative movement between the cleaving blade and fiber holder and precisely control positioning of the blade along the axis of the fiber. In one embodiment, a cleaver blade is mounted on a translation stage which is movable relative to a stationary platform which supports the fiber holder. The cleaver blade mechanism is movable along the stage so as to precisely locate the blade for a cleaving operation. The cleaver is useful for producing stacks of different optical fibers fusion spliced together and ensuring that each fiber in the stack is precisely the correct length to maximize its characteristics. The measuring device or position indicator is coupled to the traversing mechanism and can be calibrated to a start position at the end of a first optical fiber.

Abstract: A method and system for providing precise alignment of optical fiber cores to prepare for the splicing thereof without requiring specialized splicer optical systems or extensive redesigns of existing splicer optical systems. The optical fibers themselves are used to magnify an image of the cores at the splice point of the optical for precise alignment thereof. That is, in an optical fiber splicer having an optical system, the imaging device utilizes the cladding of optical fibers that are to be spliced together to precisely align the axial cores of the optical fibers.

Abstract: The present invention introduces system and method for an enhanced mass splice measurement system for testing a plurality of optical fiber splices and also the reliability of the mass fusion splicer itself. In one embodiment, a first light signal may be transmitted through each of a plurality of optical fibers at one end. At the other end, the plurality of optical fibers may be optically coupled to an integrating sphere using a fiber holder and an adapter. A light meter may be coupled to the integrating sphere for measuring the first light signal received at the integrating sphere. Once the first light signal has been measured, the fiber holder having the ends of the optical fiber may be removed from the integrating sphere and/or adapter and installed in a mass fusion splicer. A second fiber holder having ends of a second fiber cable may be installed in the mass fusion splicer.

Abstract: A fiber-splice protection label or sleeve for one or more optical fiber fusion splices. The label is provided with a unique indicium such as a serial number in alphanumeric and/or barcoded forms. The indicium may be in the form of a strip of paper, plastic, foil, or other suitable material inserted between the inner and outer sleeve or otherwise embedded in the unit. The serial number may also be printed directly on the inner sleeve, outer sleeve, or support rod, and/or in the form of a sleeve. A hologram and/or other security feature may be used to prevent tampering or creation of counterfeit units. The number of digits are preferably chosen to allow a large number of units to be sold without duplication of numbers. Special standardized prefixes or other indicia may be chosen for government or other special applications. Serial numbers may further be encoded into a micro-miniature memory “chip” embedded in, e.g., the outer sleeve.

Abstract: The present invention introduces an arc shaping member to be used in fiber optic fusion splicers. The use of the an arc shaping member may minimize the undesirable effects of grunge and/or deposits than can buildup on arc electrodes. The buildup of grunge or other deposits can cause formation of an irregular electrical arc possibly resulting in an undesirable splice. The arc shaping member may be a passive or active. In a fiber optic splicer, the arc shaping member may be mounted in a plane parallel to the optical fiber(s) being spliced and in a plane perpendicular to the arc electrodes. The arc shaping member may be installed such that the member surrounds the electric arc created by the arc electrodes. The presence of the arc shaping member causes the electric arc to maintain the desired shape and/or intensity. An operator may control, independent of the arc voltage, the shape, size and heat intensity of the electrical arc.

Abstract: An optical fiber ribbon splice tester includes an acoustic sensor. A force applicator applies a tensile force to an optical fiber ribbon that contains a plurality of splices. The acoustic sensor detects sounds generated from the splices when the force is applied. A controller is connected to the acoustic sensor and is programmed to indicate when the sound corresponds to at least one defective splice.
