Abstract: The present disclosure provides coating compositions and cured products formed from the coating compositions. The cured products can be formed at high cure speeds from the coating compositions and feature low Young's modulus, high tear strength, and/or high tensile toughness. The cured products can be used as primary coatings for optical fibers. The primary coatings provide good microbending performance and are resistant to defect formation during fiber coating processing and handling operations. The coating compositions include an oligomer, an alkoxylated monofunctional acrylate monomer, and preferably, an N-vinyl amide compound.

Abstract: Fiber coatings with low Young's modulus, high tear strength, and/or high critical stress are realized with coating compositions that include an oligomeric material formed from an isocyanate, a hydroxy acrylate compound and a polyol. The oligomeric material includes a polyether urethane acrylate and a di-adduct compound. The reaction mixture used to form the oligomeric material 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 high critical stress, high tear strength, and a high ratio of tear strength to Young's modulus.

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: Fiber coatings with low Young's modulus and high tear strength are realized with coating compositions that include an oligomeric material formed from an isocyanate, a hydroxy acrylate compound and a polyol. The oligomeric material includes a polyether urethane acrylate and a di-adduct compound, where the di-adduct compound is present in an amount of at least 2.35 wt %. The reaction mixture used to form the oligomeric material may include a molar ratio of isocyanate:hydroxy acrylate:polyol of n:m:p, where n may be greater than 3.0, m may be between n−1 and 2n−4, and p may be 2. Young's modulus and tear strength of coatings made from the compositions increase with increasing n. Coatings formed from the present oligomers feature high tear strength for a given Young's modulus.
