FIBER OPTIC CABLES AND ASSEMBLIES FOR FIBER TOWARD THE SUBSCRIBER APPLICATIONS

摘要

A fiber optic cable includes an optical fiber, strength components disposed on opposite sides of the optical fiber, and a polymeric cable jacket. The optical fiber includes a glass core, a glass cladding, and a polymer coating. The cable jacket surrounds the optical fiber and the strength components. Further, the cable jacket is tightly drawn onto the optical fiber, where excess fiber length of the optical fiber is such that positive strain is present in the optical fiber at room temperature (25° C.).

1. A fiber optic cable comprising:
an optical fiber comprising a glass core, a glass cladding, and a polymer coating; a first elongate strength component and a second strength component, wherein the first strength component and the second strength component are disposed on opposite sides of the optical fiber from one another and are generally aligned along a common plane with the optical fiber, wherein spacing between inner surfaces of the first and second strength components is in the range of about 0.8 to 1.5 millimeters, with the inner surfaces a distance of between about 0.4 to 0.75 millimeters on either side of the center of the optical fiber, and wherein the first and second strength components are larger in cross-sectional size than the optical fiber, whereby the first and second strength components shoulder crushing forces applied to the cable and thereby reduce attenuation of the optical fiber due to the crushing forces; and a polymeric cable jacket, wherein the cable jacket surrounds the optical fiber and the first and second strength components, and wherein strain is present in the optical fiber at room temperature (25° C.).
