Abstract: A cable includes a jacket defining an exterior of the cable and a rigid tube. The cable further includes densely-packed strength members on the outside of the rigid tube, compressed between the rigid tube and the jacket, and loosely-packed strength members on the inside of the rigid tube. Further the cable includes a core that is interior to the tube.

Abstract: A rugged micromodule cable includes central strength yarns, micromodules stranded around the central strength yarns, additional strength yarns positioned around the stranded micromodules, and a jacket of polymeric material surrounding the additional strength yarns. The micromodules each include sheathing surrounding a plurality of optical fibers. The strand profile of the micromodules is tight, having an average lay length of less than 250 mm, and the sheathing is thin-walled, having an average thickness of less than about 200 micrometers. The strand of the micromodules, the positioning of the additional strength yarns, and bonding between the additional strength yarns and the jacket mitigate lengthwise movement of the optical fibers in the rugged micromodule cable.

Abstract: Fiber optic assemblies include subunit cables wrapped in binders. The assemblies have small cross sections and low bend radii while maintaining acceptable attenuation losses. Stranding of the subunit cables allows ease of access to the individual cables during installation.

Abstract: Fiber optic cables are disclosed that include at least one optical fiber and a flame-retardant cable jacket. The flame-retardant cable jacket has a cavity wherein the at least one optical fiber is disposed within the cavity. The flame-retardant cable jacket includes one or more flame-retardant additives and the flame-retardant cable jacket is essentially free of a water-soluble component that can dissolve and migrate into the cavity. By way of example, the flame-retardant cable jacket is a polyvinyl chloride (PVC) essentially free of ammonium octamolybdate. Other variations include fiber optic cables having a barrier layer for inhibiting the migration of water into a cable cavity.

Abstract: A robust protective casing is provided that includes an inner tubing having a passageway therethrough, an outer tubing, and a plurality of flexible strength members disposed between the inner and outer tubing. The protective casing has a wall tubing thickness ratio of the inner tubing wall thickness to the outer tubing wall thickness of about 0.5 or less while still inhibiting the kinking of the protective casing during relatively small bend radii. Additionally, an outer diameter of the protective casing is relatively small while still allowing the routing of a standard sized 900 micron tight-buffered optical fiber through the passageway. Thus, the protective casing is advantageous in applications where limited space is available space. A fan-out assembly using the protective casings is also described.

Abstract: A communication cable including at least one communication element having a ripcord for ripping at least one cable component for facilitating access to the communication cable. In one embodiment, the ripcord is formed from a plurality of plies twisted together in a first direction, each of the plurality of plies being formed from a plurality of strands twisted together in a second direction. In another embodiment, the ripcord is formed from at least two different filament materials such as polyester and polyethylene.

Abstract: A fiber optic cable and manufacturing methods therefor includes a cable core that having at least one optical waveguide and at least one binder. The cable also includes a polymer layer being disposed about the at least one binder. During the extrusion of the polymer layer, the polymer layer at least partially melts the at least one binder when extruded thereover, thereby at least partially bonding the at least one binder with the polymer layer. In other embodiments, the cable is a dry fiber optic cable.
