摘要： PROBLEM TO BE SOLVED: To obtain a plastic optical fiber by coating a resin for protection, without deteriorating the transmission loss of the plastic optical fiber.
SOLUTION: A mold 24 of a coating apparatus is provided with a die 40 and a nipple 41. The thermoplastic resin 42 is supplied to the mold 24. An aperture between the die 40 and the nipple 41 serves as a liquid flow path 43, 44 of the resin. The plastic optical fiber (POF) 12 whose outside diameter is 500μm is conveyed through a nipple opening part 41a. The temperature of the resin 42 is adjusted to 120°C. The plastic coated optical fiber is obtained, by coating the POF 12 with the resin 42 and forming a protective layer 49 whose thickness L is 225μm. Since the quantity of heat on coating is 8.7 mJ, the POF 12 receives little thermal damage, and deterioration of the transmission loss is suppressed.
