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 waveguide, at least one strength member, and a jacket. The at least one strength member is a material having an average residual angle in the range of about 30 degrees to about 65 degrees during a bending test using a mandrel having a wire ratio (D/d) of about 200, The strength member is suitable, if necessary, for self-attaching to studs, hooks, or the like by bending it therearound and is also suitable for hardware such as P-clamps or other grips. In other embodiments, strength member 14 is annealed to relieve work hardening. Preferred embodiments use a steel strength member with a carbon content between about 0.30 percent to about 0.75 percent. Additionally, a coating may be applied to the strength member for environmental/corrosion protection or conductivity.
