A hybrid electrical/optical data/power cabling system includes a hybrid electrical/optical data/power transceiver device connected to a computing device. The hybrid electrical/optical data/power transceiver device includes a power transmission element that receives power and transmits the power to a first power transmission layer included in a hybrid electrical/optical data/power cable connected to the hybrid electrical/optical data/power transceiver device. The hybrid electrical/optical data/power transceiver device also includes optical data signal transmission element that transmits optical data signals to a first optical data signal transmission layer in the hybrid electrical/optical data/power cable connected to the hybrid electrical/optical data/power transceiver device. An electrical/optical data signal conversation subsystem in the hybrid electrical/optical data/power transceiver device receives and converts electrical data signals to optical data signals that it provides to the optical data signal transmission element for transmission to the first optical data signal transmission layer in the hybrid electrical/optical data/power cable.

A cable includes a communication carrying medium or a conductive medium. A jacket surrounds the medium along the length of the cable. At least one magnet is embedded within, attached to an outer surface of, or abutting an inner surface of, the jacket. The at least one magnet allows one cable to be attached to another cable, even if only temporarily, so that plural cables can be installed as a single unit. Magnetic attraction may exist as a jacket-to-jacket attraction between first and second cables. Alternatively, magnetic attraction may be used to attach a first cable to an intermediary, such as a spine, and also used to attach a second cable to the same intermediary.

A power and communications cable may include an electromagnetic waveguide, an inner metallic tubular surrounding the electromagnetic waveguide, an electrically conductive material surrounding the inner metallic tubular, an electrically insulating material surrounding the electrically conductive material, and an outer metallic tubular resistant to corrosion and abrasion surrounding the electrically insulating layer. The example system may include an electrical device locatable in the wellbore and coupleable to the cable and a control unit coupleable to the cable and operable to supply power to and communicate with the electrical device via the power and communications cable.

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.

Systems, methods and tools for the interrogation of fiber-reinforced composite strength members to assess the structural integrity of the strength members. The systems and methods utilize the transmission of light through optical fibers that are embedded along the length of the strength members. The inability to detect light through one or more of the optical fibers may be an indication that the structural integrity of the A strength member is compromised. The systems and methods may be implemented without great difficulty and may be implemented at any time in the life cycle of the strength member, from production through installation. The systems and methods have particular applicability to bare overhead electrical cables that include a fiber-reinforced strength member.
