The present disclosure relates to a cable having a light-emitting element. An exemplary embodiment of the cable has, in addition to the light-emitting element, a cable core comprising at least one cable construction element. The cable also has a reflective layer, which at least partially surrounds the cable core along a tangential direction with respect to a cable axis of the cable and which is designed to reflect light that is emitted by the light-emitting element. The cable also has a sheath, which is designed to conduct the light emitted by the light-emitting element around the cable core substantially in the tangential direction and to couple said light out substantially in the radial direction with respect to the cable axis. The reflectivity of the reflective layer varies in the tangential direction.

The present invention relates to a high speed transmission cable that includes a first conductor set, a dielectric film at least partially concentrically disposed around the first conductor set and a pinched portion forming an insulating envelope around the first conductor set. The dielectric film includes a base layer having a plurality of first protrusions formed on a first major surface of the base layer, wherein the dielectric film is disposed such that the base layer is partially concentric with the conductor set and wherein a portion of the first protrusions is disposed between the first conductor set and the base layer in a region where the base layer is concentric with the first conductor set.

Systems and methods are provided for applying a protective graphene barrier to waveguides and using the protected waveguides in wellbore applications. A well monitoring system may comprise a waveguide comprising a graphene barrier, wherein the graphene barrier comprises at least one material selected from the group consisting of graphene, graphene oxide, and any combination thereof; a signal generator capable of generating a signal that travels through the waveguide; and a signal detector capable of detecting a signal that travels through the waveguide.

There is provided a cable including at least one optical fiber cable, at least two electrical cables provided so as to sandwich the optical fiber cable, and plugs positioned at both ends and each having an electrical contact part connected to each of the electrical cables.

A traceable cable assembly includes a traceable cable having at least one data transmission element, a jacket at least partially surrounding the data transmission element, and first and second tracing optical fibers extending along at least a portion of a length of the traceable cable. The traceable cable assembly also includes a connector provided at each end of the traceable cable. The first and second tracing optical fibers each have a light launch end and a light emission end. The light launch ends of the first and second tracing optical fibers each include a bend. The bend allows for launching of light into the light launch ends without disengaging the first or second connectors from corresponding connector receptacles.

Example embodiments provide a device that includes a main cable jacket including one or more sub-cable jackets, and each of the sub-cable jackets includes a number of conduits.

Twisted pair cables incorporated separators with cooling channels are described. A cable may include a plurality of twisted pairs of individually insulated electrical conductors, and a separator extending lengthwise along a longitudinal length of the cable may be positioned between at least two of the plurality of twisted pairs. The separator may include a flexible body configured to maintain the at least two pairs in a predetermined configuration. A first channel extending lengthwise may define a longitudinal cavity through the separator, and at least one second channel may extend from the first channel through the flexible body to an outer surface of the separator. Additionally, the cable may include a jacket formed around the plurality of twisted pairs and the separator.

A shielded combined optical communication and conductor cable is provided. The cable includes a cable body having an inner surface defining a channel within the cable body. The cable includes an optical transmission element located within the channel and an electrical conducting element located within the channel. The cable includes an electromagnetic shield located within the channel and surrounding at least the electrical conducting element. The electromagnetic shield includes an elongate yarn strand or other strand material that supports a metal material that acts to limit electromagnetic fields from traversing across the electromagnetic shield. The strands may be unbraided and may be helically wrapped or longitudinally positioned within the cable body.

Systems and methods presented herein provide for elastomeric and flexible cables. In one embodiment, an elastomeric cable comprises an elastomeric core (e.g., a stretchable polymer) and at least one cabling component wound about the elastomeric core along a length of the elastomeric core.
