摘要: The invention relates to a recoating method for optical fiber, and in particular to prevent incorporation of bubbles into the recoating resin. In a recoating method for optical fiber, a bare fiber portion of an optical fiber is recoated by guiding recoating resin into mold forms, and the injection speed of the recoating resin injected into the mold forms is such that bubbles are not trapped due to the resin injection. This injection speed is preferably equal to or less than 6 mm/second.

摘要: An optical fiber splicer for splicing a plurality of first optical fibers arranged in spaced relationship with each other and a plurality of second optical fibers arranged in opposed relationship with the first optical fibers. The optical fiber splicer includes an XY table movable in XY directions orthogonal to each other, a tray mounted on the XY table, and first and second clamps for respectively clamping a selected one of the first optical fibers and a selected one of the second optical fibers to be spliced to the selected first optical fiber. The optical fiber splicer further includes first and second electrodes extending vertically and aligned with each other, first and second cameras located so as to interpose the first electrode, and an image processing unit for processing images picked up by the first and second cameras.

摘要: The present invention relates to an optical fiber recoating device, and to an improvement in the molds employed in this device. The optical fiber recoating device is provided for filling a recoating resin into molds, wherein semicircular mold grooves in molds into which the recoating resin is filled are longer than a bare fiber portion of an optical fiber, and an outer diameter of mold groove is larger than the outer diameter of semicircular sheath engaging grooves that engage a sheath of the optical fiber. As a result, a cylindrically shaped extending portion which extends to the sheath is formed to each end of the recoated sheath, so that joining strength of the recoated sheath is improved.
