摘要： A tool for fusing optical fibers is provided. The tool is preferably sized to be hand held and includes a housing having clamps that are positioned to engage recesses within a fusion sleeve placed in a chamber within the housing for holding down the sleeve. The housing includes a current source and conducting terminals for contacting and for providing an electric current to portions of the sleeve so that a heating element within the sleeve can fuse the first and second optical fibers together.

摘要： A consumable fusion block for fusing optical fibers includes non-conducting substrate with at least one flat surface. A pair of electrodes overlay the flat surface of the substrate and are spaced apart on either side of a passline such that each electrode tip end is adjacent the passline. A space between the electrode tips defines an arc region which can be covered to form a semi-enclosed arc region. A method is also provided for manufacturing a plurality of fusion blocks from a single slab of non-conducting material by overlying the non-conducting material with a length of conducting material, bonding the conducting material to the non-conducting material, and cutting the slab into smaller fusion blocks.

摘要： An optical fiber splice element is provided that includes a base member (12) having a fusion element (20) for aligning optical fibers (37) for fusion within. A covering member (14) is provided for covering and forming an enclosure with the base member in a closed position. The covering member can be a separate member or alternatively can be in the form of a hinged lid. At least one of the covering member and the base member including a locking mechanism (32) for maintaining closure in a closed position. The optical fiber splice element in an open position has an opening at either end for accommodating one or more optical fibers. Two conductive copper tracks (24) are each electrically connected by a copper plated barrel of a through hole (26) to a conducting pad (not shown) on the underside of the ceramic block (20). The copper tracks (24) can be bonded to the ceramic block (20) by being printed, glued, or plated thereon. The end (25) of each copper track (24) forms an electrode. A V-groove is provided in the splicing element for guiding the optical fiber in an alignment groove (28) in the ceramic block (20). When the lid (14) is closed on the base portion (12), holding means shown as protrusions (16) in the lid abut and hold optical fibers securely within the groove (22). The protrusions (16) are somewhat compliant and preferably resilient so that they form around the fibers and tightly squeeze the fibers without damaging them, yet at the same time, provide clamping upon the fibers serving as a strain relief.
