Abstract: An optical fiber ribbon is formed by connecting a plurality of optical fiber colored core wires to each other with a connector formed of a UV curable resin. Each of the optical fiber colored core wires 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 75% of a saturated Young's modulus of the primary layer.

Abstract: Disclosed is a method for manufacturing an intermittently connected optical fiber ribbon that includes a plurality of optical fibers arranged side by side, and connection parts arranged intermittently and each connecting two adjacent optical fibers. The method involves: a step of applying, between the optical fibers, a UV-curable resin including a siloxane structure in its molecule; a step of removing a portion of the UV-curable resin applied between the optical fibers; and a step of irradiating the UV-curable resin between the optical fibers with UV rays and forming the connection parts.

Abstract: An optical fiber core having a primary layer and a secondary layer, which are laminated on a bare optical fiber. The primary layer is formed by curing an ultraviolet-curable resin composition containing a first silane coupling agent, which can be incorporated into a resin skeleton, and a second silane coupling agent, which cannot be incorporated into a resin skeleton. The first silane coupling agent contains a compound having a methoxy group, and the second silane coupling agent contains a compound having an ethoxy group.
