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, wherein the optical fiber is a bend-resistant optical fiber, such that:
attenuation at a wavelength of 850 nanometers in the optical fiber increases less than 0.5 decibels when the optical fiber is wrapped one turn around a mandrel that is 10 millimeters in diameter, andthe attenuation at the 850 nanometers wavelength in the optical fiber increases less than 0.2 decibels when the optical fiber is wrapped one turn around a mandrel that is 20 millimeters in diameter; strength components on opposite sides of the optical fiber; and a polymeric cable jacket, wherein the cable jacket surrounds the optical fiber and the strength components, and wherein strain is present in the optical fiber at room temperature (25° C.).
