Latest Patents

Tsuruaki holds a patent for a "Coated optical fiber and manufacturing method and apparatus therefor." This invention focuses on a manufacturing method and apparatus that produces a coated optical fiber with superior surface smoothness of the resin coating. The method involves forming an outer coating layer around a bare optical fiber and winding the coated optical fiber via pulleys by a take-up. The invention ensures that the surface roughness of each solid body that the outer layer of the running coated optical fiber contacts is 0.8 µm or less. Additionally, when the temperature of the outer coating layer is at room temperature or the Young's modulus of the outer coating layer exceeds 500 MPa, the surface roughness of each solid body during drawing or rewinding is maintained at 1.2 µm or less.
