An article containing an innerduct structure and a woven rope located within the innerduct structure. The woven rope an inner portion comprising a plurality of multifilament fibers in the length direction of the woven rope and a jacket portion covering the inner portion. The jacket portion contains a plurality of monofilament fibers in the length direction of the woven rope and at least one multifilament fiber in the circumferential direction interwoven with the monofilament fibers in the length direction of the jacket portion. The monofilament fibers of the jacket portion form the majority of the outer surface of the woven rope.

A plug may be deployed within a pipeline along with a fluid. The plug is coupled to a fiber optic line dispensed from fiber optic dispenser located outside or within the pipeline. The plug may transmit a signal via the fiber optic line that is indicative of the location of the plug within the pipeline. The signal may comprise light pulses associated with the traversal of a pipeline joint by the plug. The location may allow the plug to be reclaimed efficiently and economically should the plug become lodged within the pipeline. The plug may communicate other measurement information via the fiber optic line and this information may be used to adjust operational parameters associated with the pipeline.

Tools and associated methods for facilitating feeding of optical fibers into a tube. In particular, the tools and associated methods are adapted to remove overlaps and tangles in the fibers as they are being fed into the tube. In this way, the number of fibers that can be fed into a tube of given transverse cross-sectional area can be maximized.

An optical fiber pathway duct comprises a first channel configured to receive a pulling mechanism, and a second channel configured to allow one of a pullable connector and a stub end coupled to an optical fiber cable to pass through the optical pathway duct. The optical fiber pathway duct further comprises a slot disposed between the first channel and the second channel and configured to allow a pulling eye of one of the pullable connector and the stub end coupled to the pulling mechanism to pass through the optical pathway duct.

High bandwidth push-cables for high speed image or video data transmission between a camera head and a cable reel or camera control unit (CCU) are disclosed.

The specification relates to a fiber optic cable assembly. The fiber optic cable assembly includes: an outer sheath; fiberglass reinforced panels; a pull material; an inner jacket; a strength material; non-interlocking armor; and a tight buffer of optical fibers.

An apparatus including a blowing chamber house having a cable inlet opening, a cable outlet opening, a fluid inlet opening for receiving a supply of pressurized fluid. A fluid flow control for controlling flow of pressurized fluid to the fluid inlet opening of the blowing chamber house. A pushing drive and a conveyor including conveyer parts arranged at opposing sides of a cable guidance space and configured to be driven by the pushing drive. The control is arranged to determine a measure of resistance to a cable being installed into the conduit by the conveyor and for controlling the operation of the apparatus in accordance with the determined measure of resistance. The control is arranged to control the fluid flow control to increase the flow of pressurized fluid into the blowing chamber house in response to an increase in the determined resistance.
