摘要： Provided is an optical fiber ribbon and an optical fiber cable, which are adaptable to manufacture at a high velocity, in the intermittent connecting type optical fiber ribbon obtained by adhering and connecting adjacent colored optical fibers by intermittent connecting portions. In an optical fiber ribbon 2 of the present invention, since, in addition to polyol having a weight average molecular weight in a specific range, cellulose nanofiber is contained in a specific range in a material forming an intermittent connecting portion 3, the Newtonian region between a low shear rate region and a high shear rate region of the material forming the intermittent connecting portion 3 can be adjusted. Thus, scattering of the material due to a centrifugal force generated by rotation of an application roll that applies the material at the time of manufacture and the like can be suppressed, and the application amount to colored optical fiber 1 can be stabilized. In addition, the optical fiber ribbon 2 can maintain suppression of such scattering and the like even in the manufacture at a high linear velocity.

摘要： In an embodiment of the present invention, provided is an optical fiber including a glass core, and a polymer cladding formed around the glass core, the polymer cladding containing a mixture of a polymerizable composition and a silane coupling agent, and a fluorine-based ultraviolet curable resin. The mixture contains 5 to 95 parts by weight of the silane coupling agent based on 100 parts by weight of the total weight of the mixture. The fluorine-based ultraviolet curable resin alone has a refractive index in a range of 1.350 to 1.420 after ultraviolet curing. A component originated from the silane coupling agent is concentrated within a range of 20 µm or less in the polymer cladding from an interface between the glass core and the polymer cladding.
