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.

摘要： A fiber optic cable having optical fibers disposed in buffer tubes, the buffer tubes defining at least two layers generally stranded about a center area of the cable. The buffer tube layers define a relatively inner layer of buffer tubes being closer to the center area, and an outer layer of buffer tubes being relatively further from the center area. The inner and outer buffer tube layers each having a respective helix value, the respective helix values being substantially the same. Alternatively, the respective helix values can be substantially non-equal. In addition, fiber optic cable systems including balanced helix factors have optical connections between layers of buffer tubes of the respective cables.

摘要： A fiber optic cable and methods of manufacturing the same includes at least one optical fiber, and at least one ferrule. The at least one ferrule is attached to the at least one optical fiber before the cable jacket is applied. The cable jacket surrounds the at least one optical fiber and the at least one ferrule so that when the cable jacket is opened the at least one optical fiber having the at least one ferrule attached may be accessed. Consequently, the when opening the cable, the craft is presented with an optical fiber that is preterminated with a ferrule. Optionally, the ferrule can have a cover or be a portion of a fiber optic connector. The cable is manufactured so that one or more of the ferrules are appropriately placed along the length of the fiber optic cable for distribution into the fiber optic network.

摘要： A fiber optic cable including at least one optical fiber and a strength member surrounding the optical fiber. The strength member can include a plurality of fibers disposed in a matrix such that the resulting strength member preferably has a modulus of elasticity of at least about 20 GPa and, more preferably, at least about 40 GPa. While the strength member can be an integral member, the strength member can be formed of at least two physically distinct portions in order to more precisely tailor the characteristics of the fiber optic cable. In this regard, the strength member can include a first strength member surrounding the optical fiber that includes a first matrix and a plurality of first fibers embedded within the first matrix, and a second strength member surrounding the first strength member that includes a second matrix and a plurality of second fibers embedded within the second matrix. The fiber optic cable can also include a release layer disposed between the optical fiber and the strength member to facilitate separation of the strength member from the optical fiber.

摘要： Fiber optic cables, and methods of manufacturing the same, include a plurality of carriers having at least one optical fiber therein. In one embodiment, the carriers are arranged in two layers within the cable and are generally disposed about a center area of the cable. Each layer has a respective helix-plus-EFL value. A difference between the respective helix-plus-EFL values of the layers defines a differential range being, preferably, about 1% or less. Additionally, the fiber optic cables can be used in fiber optic cable systems such as dispersion managed cable systems (DMCS).
