光ファイバー
Optical fiber recoating is the process of restoring the primary coating to stripped optical fiber sections after fusion splicing. The polymer comprising the recoat is usually similar in composition to the original fiber polymer coating. Nyfors optical fiber recoaters are designed to restore the primary coating on spliced optical fibers with acrylate coatings. Due to the mould design, the restored part of the coating has a diameter and other properties, such as eccentricity and roundness, that are almost identical to the original fiber.
