  • COLORED OPTICAL FIBER, OPTICAL FIBER RIBBON, OPTICAL FIBER RIBBON CABLE AND METHOD FOR MANUFACTURING THE SAME
    Publication number: 20240116808
    Abstract: A colored optical fiber includes a bare optical fiber, a primary layer formed of a first ultraviolet curing resin covering the bare optical fiber and a secondary layer formed of a second ultraviolet curing resin covering the primary layer. An outer diameter of the secondary layer is smaller than or equal to 210 ?m. A Young's modulus of the primary layer is smaller than or equal to 88% with respect to a saturated Young's modulus of the primary layer.
    Type: Application

  • COLORED OPTICAL FIBER, OPTICAL FIBER RIBBON, ASSEMBLY CABLE OF SINGLE FIBERS, RIBBON CABLE AND METHOD FOR MANUFACTURING THE SAME
    Publication number: 20230257301
    Abstract: Provided is a colored optical fiber of which a primary layer is easily formed. The colored optical fiber includes a bare optical fiber, a primary layer formed of an ultraviolet curing resin covering the bare optical fiber, and a secondary layer formed of an ultraviolet curing resin covering the primary layer. Young's modulus of the primary layer is smaller than 70% with respect to a saturated Young's modulus of the primary layer. The saturated Young's modulus of the primary layer is larger than or equal to 0.84 MPa.
