Optical fiber ribbon, optical fiber cable, and method of manufacturing optical fiber ribbon

A method of manufacturing an optical fiber ribbon, 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;
• forming a colored layer by applying a UV curable resin around the primary layer and irradiating the UV curable resin with UV light;
• and
• forming an optical fiber ribbon by applying a UV curable resin to a plurality of optical fiber colored core wires irradiating the UV curable resin with UV light and curing the UV curable resin to connect the plurality of optical fiber colored core wires to each other, wherein
• the primary layer, after forming of the optical fiber ribbon, has a Young's modulus that is greater than or equal to 75% of a saturated Young's modulus of the primary layer.

An optical fiber ribbon comprising:

• a plurality of optical fiber colored core wires that are connected to each other with a connector that comprises a UV curable resin, wherein
• each of the optical fiber colored core wires comprises:
• a bare optical fiber;
• a primary layer that comprises a UV curable resin that covers the bare optical fiber;
• and
• a colored layer disposed outside the primary layer and that comprises a colored UV curable resin, and
• the primary layer has a Young's modulus that is greater than or equal to 75% of a saturated Young's modulus of the primary layer.
