摘要： A fiber optic cable includes an optical fiber, a strength layer surrounding the optical fiber, and a jacket assembly surrounding the strength layer. The jacket assembly includes a foam. A method for manufacturing a fiber optic cable includes mixing a base material, a chemical foaming agent and a shrinkage reduction material into a mixture in an extruder. The mixture is heated so that the base material and the chemical foaming agent form a foam with shrinkage reduction material embedded into the foam. An optical fiber and strength layer are fed into a crosshead. The mixture is extruded around the optical fiber and the strength layer to form a jacket assembly.

摘要： A lashing assembly lashes together two or more fiber optic telecommunications cables. The lashing assembly comprises at least a first and a second bobbin. As the cables are passed through the first bobbin, twine pays off from the first bobbin and wraps around the cables in a clockwise helix. As the cables are passed through the second bobbin, twine pays off from the second bobbin and wraps around the cables in a counterclockwise helix. In this way, the twine from the first and second bobbins lash the cables together as the cables are passed through the first and second bobbins.

摘要： A method for installing a fiber optic cable assembly includes providing a fiber optic cable assembly. The fiber optic cable assembly includes a first jacket, a strength layer, and a second jacket. The strength layer surrounds the first jacket and includes a first set of strength members helically wrapped around the first jacket and a second set of strength members reverse helically wrapped around the first jacket. The first and second sets of strength members are unbraided. The method further includes routing the fiber optic cable assembly from a fiber optic enclosure to an end location. A portion of the second jacket at an end of the fiber optic cable assembly is split. The portion of the second jacket is removed.

摘要： A fiber optic cable includes an inner jacket and an outer jacket. The inner jacket surrounds an optical fiber and a strength layer positioned between the optical fiber and the inner jacket. The inner jacket includes a liquid crystal polymer within a base polymeric material. The outer jacket defines an elongate transverse cross-sectional profile. A strength member is positioned outside the inner jacket. The outer jacket is removable from the inner jacket such that the fiber optic cable forms a first cable portion that extends from a first end of the fiber optic cable to an intermediate location of the fiber optic cable and a second cable portion that extends from the intermediate location to a second end of the fiber optic cable. The first cable portion is more rugged than the second cable portion.

摘要： A fiber distribution hub includes a swing frame pivotally mounted to an enclosure. The enclosure defines a cable port and at least a first interface region. The swing frame defines a splitter region, a termination region, and a storage region. Splitter modules can be oriented and positioned so that splitter pigtails extending from each of the splitter modules extend directly downwardly through a vertically extending channel. A cable clamp can be mounted to the enclosure at the cable port to secure one or more cables to the enclosure.
