Recoating method and recoating apparatus for optical fiber

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 (11A, 11B), 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.
