The present invention discloses a metal wire armored optoelectronic hybrid cable, which comprises an optoelectronic hybrid unit, a metal wire armoring and an outer protection casing. The optoelectronic hybrid unit comprises an electrical unit and an optical unit which are mixed. The metal wire armoring wraps the optoelectronic hybrid unit. The outer protection casing wraps the metal wire armoring. In the present invention, due to the use of the metal wire armoring, the bending performance is favorable, the production and processing processes are simple, and the production cost of the hybrid cable is greatly reduced.

It is disclosed a cable assembly comprising a common figure-8 outer jacket comprising a first lobe and a second lobe, wherein the first lobe surrounds an electric core with a relevant first extruded inner sheath housing a strength member; and the second lobe surrounds an optical core with a relevant second extruded inner sheath.

A hybrid or composite cable may include a core component and a plurality of buffer tubes positioned around the core component. The core component may include a plurality of twisted pairs of individually insulated conductors and a filling compound positioned between and around the plurality of twisted pairs. The filling compound may have a density of less than approximately 0.70 g/cm.sup.3 and may further include a plurality of microspheres. Each of the plurality of buffer tubes may be configured to house at least one optical fiber. Additionally, a jacket may be formed around the core component and the plurality of buffer tubes.

A cable may include a central strength member, a plurality of optical fiber buffer tubes positioned around the central strength member, and a jacket surround the plurality of buffer tubes and the central strength member. The central strength member may include a plurality of longitudinally extending and twisted conductive components. Each conductive component may include an inner conductor, a dielectric strength member formed around the inner conductor and having a tensile strength of at least 10,000 MPa, and an outer conductor formed around the dielectric strength member. The inner and outer conductor may form a balanced pair of conductors.

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.

A hybrid cable applicable in oil wells is disclosed, comprising a FIMT, a conductor layer formed by continuous laser welding and cylindrically covered the outer surface of the FIMT, the outer cylindrical surface of the conductor layer being covered with a high temperature resistant insulating layer by a continuous extrusion method or by wrapped helically with insulating tapes around the outer surface of the conductor layer and the external steel tube cylindrically covered the outer surface of the insulating layer. The conductor layer is coaxial with the FIMT, the inner space of the hybrid cable to accommodating excess length of the optical fiber for thermal expansions or the tensile stress of the optical cable. The thickness of the insulating layer cylindrically covered the outer surface of the conductor layer can be increased, thereby improving the insulating property. A method of manufacturing such hybrid cable is disclosed.
