RESIN COATING METHOD FOR COATED OPTICAL FIBER JUNCTURE

摘要

PURPOSE:To provide the resin coating method for a coated optical fiber juncture capable of forming a resin coating having good outside diameter accuracy. CONSTITUTION:This resin coating method for the coated optical fiber juncture comprises subjecting the juncture formed by butting the terminals of bare optical fiber parts 2 from which the resin coatings of the coated optical fiber 1 are removed and fusion splicing these parts to recoating with a UV curing resin 3. The bare optical fiber parts 2 are passed through a die 4 to coat the bare optical fiber parts 2 with the UV curing resin 3. The UV curing resin applied on the bare optical fiber parts is irradiated with UV rays 5 within 0.5 seconds after going out of the die 4, by which the UV curing resin is cured.
