摘要：
A colored optical fiber comprises 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, wherein a Young's modulus of the primary layer is smaller than 70% with respect to a saturated Young's modulus of the primary layer, and wherein the saturated Young's modulus of the primary layer is smaller than or equal to 0.85 MPa.
