    摘要: Disclosed are fiber optic assemblies having at least one optical fiber and at least one water-swellable yarn disposed within a tube that preserves optical performance. Optical performance is preserved by selecting water-swellable yarns for the fiber optic assemblies that are softer and loftier since at least some of the filaments have a textured characteristic. In one embodiment, the water-swellable yarn has a stretch ratio of about 2 or more, where the stretch ratio is defined as the nominal unstretched diameter divided by the nominal stretched diameter. In another embodiment, the water-swellable yarn has a textured elongation factor of about 2% or more. Additionally, embodiments may position the optical fibers radially outward of the water swellable yarn(s), thereby further preserving optical performance.

    摘要: A fiber optic cable includes at least one optical fiber, at least one strength member, at least one dry insert, and a cable jacket. The cable jacket has a cavity with a generally rectangular cross-section with the at least one optical fiber and the at least one dry insert disposed therein. The at least one optical fiber has a predetermined level of coupling to the cable jacket that is provided by the at least one dry insert within the cavity of cable jacket. The predetermined level of coupling is about 0.1625 Newtons or more per optical fiber for a thirty meter length of fiber optic cable. Additionally, fiber optic cables of the present invention are also suitable as a portion of a cable assembly.
