Abstract: A method includes applying a coupling agent solution to a major surface of a continuously moving glass ribbon to form a coupling agent coated region of the glass ribbon. The glass ribbon is a flexible glass ribbon having a thickness of at most about 300 μm. The method includes heating the coupling agent coated region of the glass ribbon to form a coupling agent treated region of the glass ribbon and winding the glass ribbon onto a collection roll. A glass ribbon has a thickness of at most about 300 μm and a major surface. At least a portion of the major surface includes a coupling agent treated region. Upon forming a polymeric layer on the coupling agent treated region at least five months after forming the coupling agent treated region, the polymeric layer has a peel force of at least 200 gf/in.

Abstract: Methods of applying adhesion promoters to optical fibers are described. The methods include direct application of an adhesion promoter onto the surface of the optical fiber. The adhesion promoter is applied in liquid form as a neat compound or as a component of a liquid solution to the surface of the optical fiber. The adhesion promoter bonds to the optical fiber and includes functional groups that permit bonding with an overlying polymer coating to improve the adhesive strength of the polymer coating to the fiber.

Abstract: The present description provides reduced-diameter multimode optical fibers. The optical fibers include a reduced-diameter glass fiber and/or reduced-thickness coatings. The overall diameter of the optical fibers is less than 210 μm and examples with diameters less than 160 μm are presented. Puncture resistant secondary coatings enable thinning of the secondary coating without compromising protection of the glass fiber. The optical fibers are suitable for data center applications and features high modal bandwidth, low attenuation, low microbending sensitivity, and puncture resistance in a compact form factor.

Abstract: An optical fiber includes an outer diameter less than 220 μm, a glass fiber that includes a glass core and a glass cladding, a primary coating, and a secondary coating. The glass cladding surrounds and is in direct contact with the glass core. The primary coating surrounds and is in direct contact with the glass fiber. The primary coating can have a Young's modulus less than 0.5 MPa and a thickness less than 30.0 μm. The secondary coating surrounds and is in direct contact with the primary coating. The secondary coating can have a thickness less than 27.5 m. A pullout force of the optical fiber can be less than a predetermined threshold when in an as-drawn state. The pullout force may increase by less than a factor of 2.0 upon aging the primary and secondary coatings on the glass fiber for at least 60 days.

Abstract: Fiber coatings with low Young's modulus, low fiber pullout force for fibers in the as-drawn state, and small time-dependent increases in pullout force as the fiber ages. The fiber coatings are cured products of coating compositions that include an oligomer formed from an isocyanate, a hydroxy acrylate compound and a polyol. The oligomer includes a polyether urethane acrylate and a di-adduct compound. The reaction mixture used to form the oligomer includes a molar ratio of isocyanate:hydroxy acrylate:polyol of n:m:p, where when p is 2, n is in the range from 3.0 to 5.0 and m is in the range from 1.50n-3 to 2.50n-5. Control of the n:m:p ratio leads to compositions that, when cured, provide coatings and cured products having low Young's modulus, low pullout force on glass, and weak variations with time as the fiber ages.
