摘要： A method of fusion splicing optical fibers. Cores of the optical fibers to be fusion spliced are arranged in such a manner that the ends of the corresponding cores of optical fibers opposingly face to each other between discharge electrodes for fusion splicing. Discharge current flowing between the discharge electrodes is automatically adjusted according to a number of the cores of the optical fibers to substantially provide an optimal correction to the discharge current in relation to the number of the cores of the optical fibers. The discharge current is further adjusted to a variation in atmospheric pressure to substantially provide an optimal correction to the discharge current in relation to the variation in atmospheric pressure.

摘要： In a method of preventing twisting of a fusion-spliced optical fiber in the process of encasing the optical fiber in a casing, one of a pair of optical fibers is wound N turns in one direction to form a first coil. Another of the pair of optical fibers is wound N turns in another direction opposite to the direction to form a second coil. Ends of remainder portions of the optical fibers which are not wound are fusion-spliced to each other to form a fusion-spliced portion. The fusion-spliced portion is fixed within a casing. The remainder portions of the optical fibers are pushed into the casing to expand the first and second coils.

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 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.
