Abstract: Micromodule subunit cables are constructed to allow for ease of identification between optical fibers in differing groups of optical fibers. In one cable, a first group of fibers is located within a buffer tube core while a second group of fibers is located within the cable jacket, but outside of the core. The fibers in the first and second groups can accordingly use the same color coding sequence without requiring additional indicia such as stripes or binding.

Abstract: A ruggedized cable has an inner and an outer jacket. The cable also includes two layers of aramid strength elements for tensile strength. The cable can be pulled through various environments due to the jacketing and strength elements. The outer jacket and strength elements can be stripped away at a transition point, and secured at an entry point of a housing of an FDT, ONT, etc. The remaining inner cable element is then routed through the hardware housing and terminated.

Abstract: A tube assembly of the present invention has at least one subunit with at least one dry insert generally surrounding the subunit which may be disposed within a tube, thereby forming a tube assembly. The subunit includes a fiber optic ribbon and a sheath, wherein the sheath is tight-buffered about the fiber optic ribbon, thereby inhibiting buckling of the ribbon during temperature variations. Additionally, the tube assembly can be a portion of a fiber optic cable having a sheath that may include a plurality of strength members and a cable jacket. In other embodiments, the subunits and dry insert are disposed within a cavity, thereby forming a tubeless cable. Additionally, subunits may include a marking indicia for denoting the security level.

Abstract: Disclosed is a fiber optic drop cable including at least one optical waveguide, at least one roving, and a cable jacket. In one embodiment, the at least one roving includes a resin matrix having a water-based acrylic composition that includes an ethylene-acrylic acid and a water-swellable component. The resin matrix has a percent by weight of about 10 percent or less of the flexible roving so that the at least of one roving is at least partially bonded with the cable jacket, thereby inhibiting buckling of the cable jacket. In another embodiment, a plurality of rovings are arranged in clusters in the cable for influencing the bonding between the rovings and cable jacket. Also, disclosed is a protective casing for protecting and routing optical fibers along with preconnectorized cable assemblies.

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.
