Document Type and Number:
WIPO Patent Application WO/2022/092089
Kind Code:
A1
Abstract:
The present invention provides a colored optical fiber core wire wherein a primary layer is easy to form. This colored optical fiber core wire (1) is provided with: a bare optical fiber (2); a primary layer (3) which is formed of an ultraviolet curable resin so as to cover the bare optical fiber (2); and a secondary layer (4) which is formed of an ultraviolet curable resin so as to cover the primary layer (3). The Young's modulus of the primary layer (3) is less than 70% with respect to the saturated Young's modulus of the primary layer (3); and the saturated Young's modulus of the primary layer (3) is 0.84 MPa or more.
