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: A hybrid cladding for optical fibers used in short data networks. The hybrid cladding surrounds a glass waveguide fiber and is surrounded by a primary coating. The hybrid cladding has low adhesion to the primary coating. The low adhesion permits stripping of the primary coating from the hybrid cladding without damaging the hybrid cladding and without leaving residue of the primary coating on the surface of the hybrid cladding. The hybrid cladding may be formed by curing a composition that includes a monomer with a radiation-curable functional group, a slip component, and a photoinitiator. The radiation-curable functional group may be a (meth)acrylate group. The slip component may contain silicon or silicone and may further contain a radiation-curable functional group. Silicone di(meth)acrylate is an illustrative slip component.

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 μm. 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: A multi-purpose optical fiber with coating is provided. The optical fiber can function as a transmission fiber or as a coupling fiber for optical data links that features low coupling loss to silicon photonics lasers, VCSELs, single mode transmission fibers, multimode transmission fibers, and high speed receivers. The fiber includes a core, an optional inner cladding region, a depressed index cladding region, an outer cladding region, and a coating. The relative refractive index profile of the coupling fiber includes a small-radius core region with α profile and a depressed index cladding region that facilitates low bending loss and high bandwidth. The coating thickness and overall diameter of the fiber is small.

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, 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.
