Abstract
An optical fiber colored core wire includes: a bare optical fiber; a primary layer that comprises a UV curable resin that covers the bare optical fiber; a secondary layer that comprises a UV curable resin that covers the primary layer; and a colored layer disposed outside the secondary layer and that comprises a colored UV curable resin. The primary layer has a Young's modulus that is greater than or equal to 70% of a saturated Young's modulus of the primary layer.
Claims8
An optical fiber colored core wire comprising:
- a bare optical fiber;
- a primary layer that comprises a UV curable resin that covers the bare optical fiber;
- a secondary layer that comprises a UV curable resin that covers the primary layer;
- and
- a colored layer disposed outside the secondary layer and that comprises a colored UV curable resin, wherein
- the primary layer has a Young's modulus that is greater than or equal to 70% of a saturated Young's modulus of the primary layer.
A method of manufacturing an optical fiber colored core wire, comprising:
- forming a bare optical fiber;
- forming a primary layer by applying a UV curable resin around the bare optical fiber and irradiating the UV curable resin with UV light;
- and
- forming a colored layer by applying a UV curable resin around the primary layer and irradiating the UV curable resin with UV light, wherein
- the primary layer, after forming of the colored layer, has a Young's modulus that is greater than or equal to 70% of a saturated Young's modulus of the primary layer.
