Abstract: A coated optical fiber includes a fiber coating having an unblended primary portion on the optical fiber, an unblended secondary portion, and a blended portion intermediate the unblended primary and secondary portions. The thickness of the blended portion is greater than or equal to about 10% but less than 100% of the thickness of the fiber coating. An optical fiber ribbon includes a ribbon matrix similarly having an unblended primary portion, an unblended secondary portion, and a blended portion between the unblended primary portion and unblended secondary portion. A method for fabricating a coated optical fiber or optical fiber ribbon includes applying a primary portion material to the optical fiber or plurality of coated optical fibers, and applying a secondary portion material in a manner selected to provide a blend of the primary portion material and the secondary portion material. An applicator apparatus includes means for performing the described steps.

Abstract: There is provided a radiation-curable coating composition containing oligomers that each have two end groups X1 and X2, wherein the end groups X1 and X2, which may be the same or different, are a photoinitiator group or an adhesion promoter group. The coating composition may exclude the presence of non-reactive photoinitiator groups and non-reactive adhesion promoter groups, each of which would fail to covalently bond itself to an oligomer backbone.

Abstract: The present invention provides an improved method and apparatus for curing coatings on optical fibers, without creating additional heat and compromising the manufacturing speed of optical fibers. The present invention uses at least one ultrasonic transducer coupled to a component of the optical fiber draw tower, such as the coating die, curing stage device or sheath, to emit ultrasound to the coating of the fiber. The use of ultrasound with current coating cure techniques, such as UV radiation curing, aids in accelerating the coating cure process through the effects of sonolysis, allowing an increase in current manufacturing speeds of optical fibers.

Abstract: A fast-curing, low viscosity composition for coating an optical waveguide, more specifically, an optical fiber, and optical fibers coated therewith are disclosed. The coating composition is a radiation curable composition containing: a radiation curable oligomer, a free radical photoinitiator, and a mixture of reactive diluents including a low molecular weight (meth)acrylate having tri-, tetra-, penta- or higher functionality.
