    Abstract: The present disclosure provides optical fibers with an impact-resistant coating system. The fibers feature low microbending and high mechanical reliability. The coating system includes a primary coating and a secondary coating. The primary coating and secondary coating have reduced thickness to provide reduced radius fibers without sacrificing protection. The primary coating has a low spring constant and sufficient thickness to resist transmission of force to the glass fiber. The secondary coating has high puncture resistance. The outer diameter of the optical fiber is less than or equal to 200 μm.

    Abstract: An optical fiber curing component includes a first tube comprising a first body defining a first interior surface and a first exterior surface, the first tube defining a first aperture and a second aperture on opposite ends of a first cavity, wherein the first tube defines a central axis extending through the first cavity; light sources coupled to the first body of the first tube and configured to emit light toward the central axis of the first tube, wherein each of the light sources intersect a common plane defined perpendicular to the central axis of the first tube; a silica glass article, having an anti-reflective coating, disposed between each of the plurality of light sources and the central axis of the first tube; and a reflective coating positioned on the interior surface of the first body and configured to reflect the light toward the central axis of the first tube.

    Abstract: The systems and methods of forming optical fiber coatings with reduced defects include moving a bare optical fiber through first and second coating sub-systems. The first coating sub-system forms a first coating on the bare optical fiber by depositing a first coating material and then curing the deposited first coating material with actinic light. This process also results in the formation of stray actinic light. The process also includes moving the coated optical fiber through a second coating sub-system to form a second coating on the first coating. A light-blocking device resides between the first and second coating sub-systems to block the stray actinic light. Without the light-blocking device, the stray actinic light can enter the second coating sub-system and reach the second coating material therein and form a gel therefrom, which in turn leads to defects in the coated optical fiber exiting the second coating sub-system.

    Abstract: An optical fiber curing component includes a tube having a body defining an interior surface and an exterior surface. The tube defines a first aperture and a second aperture on opposite ends of a cavity. The tube defines a central axis extending through the cavity. A plurality of light sources is coupled to the body of the tube and configured to emit light toward the central axis of the tube. Each of the light sources intersect a common plane defined perpendicular to the central axis of the tube. A reflective coating is positioned on the interior surface of the body and configured to reflect the light toward the central axis of the tube.
