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. |
