Abstract: Furcation mounting structures for securing a plurality of furcation bodies of respective fiber optic cable assembles within the fiber optic shelf are disclosed. In one embodiment, the furcation mounting structure has a first type of aperture for attaching a first type of clip for securing a furcation body and a second type of aperture for securing a second type of clip for securing a furcation body. Consequently, the furcation management structures disclosed advantageously allow the mounting of different types of clips thereto. In other embodiments, the furcation mounting structure is mounted within the fiber optic shelf or assembly.

Abstract: A cable routing guide attached to a fiber optic apparatus, such as a module positioned on a fiber optic equipment tray is disclosed. The cable routing guide is adapted to receive a length of at least one fiber optic cable intended to be connected to a cable connection point, such as a fiber optic adapter disposed on the module. The cable routing guide allows the at least one fiber optic cable to move in response to the fiber optic equipment tray or the module moving between a first position and a second position in a manner such that the length of the at least one fiber optic cable from the cable routing guide to the fiber optic adapter remains substantially unchanged. Moreover, the at least one fiber optic cable that is received by the cable routing guide may be retained and maintained by the cable routing guide without being tensed or stressed.

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: 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: One embodiment is a fiber optic cable including at least one subunit, a tube, a plurality of strength members, and a cable jacket. 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. The tube houses at least a portion of the at least one subunit to form a tube assembly. The plurality of strength members are disposed radially outward of the tube and are surrounded by the cable jacket. Other embodiments include a plurality of subunits in a stack with each subunit having a sheath for security purposes. Additionally, a tube assembly can have a fiber optic packing density of about 0.05 or greater.
