The present invention relates to a pre-terminated (pre-terminated) optical fibre cable assembly (10,90), which is configured to be installed through a duct (20). The pre-terminated optical fibre construction (10,90) includes at least one optical fibre (46). A protective sleeve (26) is added to the optical fibre (46) before adding a terminal connector (24) to the leading end of at least one optical fibre (46). The protective sleeve (26) extends from behind the terminal connector (24) along part of the length of the optical fibre (46). When the cable is installed through a duct, the protective sleeve protects the portion of the fibre that protrudes from the end of the duct, for example in a communications cabinet (16). A residual length (28) of the protective sleeve remains within the duct. Terminal connectors and protective sleeves can be applied at both ends of the cable assembly, or only one end.

A connector includes a first connector body and a second connector body configured to be coupled to one another. The first connector body has a through hole and a cavity. The through hole and the cavity are configured to receive a shield of a hardline coaxial cable. A first washer is disposed in the first connector body and is configured to permit the shield to be pushed in a first direction through the through hole and into the cavity while resisting movement of the shield in a second direction opposite to the first direction. The second connector body has a through hole and a cavity. The through hole and the cavity of the second connector body are configured to receive a tubular member. A second washer is disposed in the second connector body and is configured to permit the tubular member to be pushed in the second direction through the through hole of the second connector body and into the cavity of the second connector body while resisting movement of the tubular member in the first direction. The second connector body is rotatable relative to the second washer and the tubular member until the second connector body and the first connector body are coupled together to a predetermined degree of tightness.

A connector assembly comprising: a first end and a second end; a first inlet for receiving a protective duct of an enhanced performance fibre unit; a second inlet for receiving a protective duct of an enhanced performance fibre unit; an outlet for receiving a protective duct of an enhanced performance fibre unit; a first internal channel between the first inlet and the outlet for receiving a length of enhanced performance fibre unit stripped of its protective duct; and a second internal channel for receiving a length of enhanced performance fibre unit stripped of its protective duct between the second inlet and a section of the first internal channel proximate the outlet.

A transmission line installation system includes a transmission line conveying apparatus that operates to install a transmission line within a conduit by advancing the transmission line through the conduit. The transmission line conveying apparatus includes a plurality of components. The components include local controllers. Communication with the local controllers of the components synchronizes operation of the components during the installation of a transmission line.

A method and apparatus for removing optic fibers from multiple spools of optic fiber involving one or more rotating trees on which spools of optic fiber are seated, a transport passage and a rotating carousel. The free end of a fiber is pulled through the passage and attached to the rotating carousel such that the rotation of the carousel removes the rest of the fiber from the spool(s). The passage can be equipped with one or more rollers to reduce the friction between the fibers and the passage. The carousel may feature retractable rails to facilitate removing the fibers. The passage may also feature a blower and/or a venturi that provides suction to facilitate the movement of one or more fibers through the passage. A reciprocating tracking unit can be used to spread the fibers onto the carousel.

A slickline that includes both electrically conductive and fiber optic capacity. The slickline includes a fiber optic thread or bundle of threads that may be surrounded by an electrically conductive member such as split half shells of copper elements. Further, these features may be disposed in a filler matrix so as to provide a cohesiveness the core of the slickline. So, for example, the line may be more effectively utilized in downhole applications such as coiled tubing operations, without undue concern over collapse or pinhole issues emerging in the line.

There are described methods and systems for deploying optical fiber within a conduit. In one aspect, an optical fiber injector comprising a pressure vessel having a fluid inlet and a fluid outlet. The fluid outlet is engaged with an open end of the conduit. A length of optical fiber is provided within the pressure vessel. The optical fiber is then jetted into the conduit by injecting a fluid into the pressure vessel via the fluid inlet. The optical fiber injector is configured such that the fluid is directed from the fluid inlet to the fluid outlet, and urges the optical fiber to move through the conduit, thereby deploying the optical fiber within the conduit. In a further aspect, there is provided a modular assembly comprising a pipeline and a line of two or more conduits arranged end-to-end. Each pair of opposing ends of adjacent conduits is connected together by a separate splice box. The line is positioned along and adjacent to a length of the pipeline.
