An assembly for installing an optical fiber cable which includes a fiber core assembly and a reinforcement yarn assembly surrounding the fiber core assembly. The assembly includes a leading unit having a yarn positioner for fixing a front part of the reinforcement yarn assembly, and a trailing unit including a front cap, a rear tube, and a middle tube that has front and rear threaded portions threadedly engage the front cap and the rear tube, respectively. The front cap has a threaded sleeve portion sleeving around the front threaded portion of the middle tube for clamping a rear part of the reinforcement yarn assembly against the middle tube, thereby fixing the rear part of the reinforcement yarn assembly.

A dust-proof apparatus for a fiber optic connector has a base; a ferrule receiving sleeve positioned on a mating end of the base; two primary cantilevered arms extending substantially in parallel from the mating end of the base, with the ferrule receiving sleeve being positioned therebetween; and a secondary cantilevered arm extending from the mating end of the base, and having a locking projection receiving hole disposed on a free end.

There is provided a male cable connector (1) for reversibly connecting a computer network cable (7) to form at least one electrical connection or one optical connection to a second component, said male cable connector (1) comprising a male member (3) enclosing at least one electrical lead (14) electrically connected to one electric contact surface (13) and the network cable (7) or said male member (3) enclosing at least one optical fiber (17) connected to an optical connection surface (22) and the network cable (7), said male member (3) being associated with a front direction which is parallel to the longitudinal axis of the male member (3) and directed from the cable (7) towards a forward end (11) of the male member (3) characterized in that said at least one electrical contact surface (13) or at least one optical connection surface (22) is arranged on the surface of the male member (3) and the male member (3) has a bore (4) for connecting a pull-cord. There is also provided a female connector, adaptors, cables and kits.

A cable assembly with electrical conductors and fiber optic lines includes a hybrid cable, electrical tethers, a fiber optic tether, and a joining location thereof that includes a shielding unit establishing an electrical contact between shielding of the hybrid cable and shielding of the respective electrical tether cables. The shielding unit includes a central body of an conductive material surrounding the hybrid and tether cables at the joining location, where the central body is in electrical contact with the shielding of the hybrid cable and with the shielding of each electrical tether.

Devices, systems and methods to prevent damage to power and communication conductors located in cold occurring regions, with an elongated cylindrical tubular assembly of closed cell foam within an outer non-conductive durable outer coating, with a pull cord extending therethrough, wherein the assembly along with communication and power lines is pulled through new power and communication ducts and conduits and in retrofitting existing power and communication ducts, so that the assembly reduces the volume spacing in the ducts/conduits that can be damaged by water intrusion which expands during freeze conditions.

A cable assembly is described that includes a preterminated optical fiber drop cable having a connector body mounted on a terminal end thereof, and a removable installation device attached to a jacket of the preterminated optical fiber drop cable by an attachment portion, wherein the attachment portion includes a pair of tear tabs that provides tool-less removal of the installation device from the preterminated optical fiber drop cable.

A dust cap includes a cap body and a pair of opposing latches. The cap body is adapted to cover a connectorized end of a fiber optic connector and cable assembly when the connectorized end is inserted through an opening of an interior of the cap body. The cap body further includes an opposing pair of resilient walls. The pair of opposing latches each include latching features that extend outside of the interior of the cap body. The pair of opposing latches each further include a mounting portion mounted to a respective one of the opposing pair of resilient walls. The dust cap may further include a pulling interface. The pulling interface may be adapted to attach to a pulling member and may be positioned at a tapered nose of the cap body. The dust cap may thereby be a cable pulling cap and may pull a fiber optic connector and cable assembly through conduits and other narrow passages. A pair of opposing pulling halves may enclose the cable pulling cap or the dust cap without a pulling interface and at least a portion of the connectorized end of the fiber optic connector and cable assembly.

A pre-terminated end of a fiber optic cable has a protective cap that protects the optical fiber and the ferrule assembly at the terminal end. The protective cap has an attachment feature enabling a pull cord to attach to the protective cap. The protective cap has a body including an exterior surface and a receptacle formed in the body and configured to receive a portion of the fiber optic cable, and the attachment feature. The attachment feature includes a cavity formed in a tip of the body and at least two openings formed in the exterior surface of the body and connected to the cavity.

An optical fiber cable includes: an optical fiber; a sheath that accommodates the optical fiber; a tension member that extends from an end portion of the sheath; a housing disposed at an end portion of the tension member; and an anchor portion disposed on the tension member. The anchor portion increases a projected area of the tension member when viewed from a longitudinal direction of the optical fiber cable, the anchor portion is inside the housing, and the housing is filled with a filler that fixes the anchor potion to the housing.

Devices, systems and methods to prevent damage to power and communication conductors located in cold occurring regions, with an elongated cylindrical tubular assembly of closed cell foam within a braided/woven layer that can be sealed to provide longitudinal strength and a snag resistant durable and flexible outer coating. The assembly along with communication and power lines is pulled through new power and communication ducts and conduits and in retrofitting existing power and communication ducts, so that the assembly reduces the volume spacing in the ducts/conduits that can be damaged by water intrusion which expands during freeze conditions.
