It is disclosed a figure of eight cable comprising a first cable element comprising a first core enclosed by a first outer sheath, a second cable element comprising a second core enclosed by a second outer sheath and a web joining the first and second outer sheaths so as to provide the cable with a major plane of symmetry X which comprises the longitudinal axes of the first and second cable elements. The cable also comprises at least one strength member embedded within the first or second outer sheath. All the strength members of the cable are substantially located on the major plane of symmetry X of the cable.

An apparatus and method for accessing and/or repairing a select subset of fibers in an ADSS fiber optic cable. The apparatus includes a housing extending from a first end to a second end. A first fiber optic splice tray is positioned within the housing closer to the first end than to the second end. A second fiber optic splice tray is positioned within the housing and spaced apart from the first splice tray. A tension member extends through the housing and includes a first mechanical connector near the first end and a second mechanical connector near the second end. The connectors provide an attachment location for deadends at either end for transferring tension from the undamaged portion of the ADSS fiber optic cable.

A device for installing an all fiber optoelectrical transducer on the base of a pin insulator column, such that the device mounts to the insulator pin column in a bushing style of concentric attachment and enables retrofits of said device to existing transmission & distribution bushing insulator equipment. A rigid and solid mechanical support region contains a hollow bushing attachment point at a center location, and radiates outward and bonds solidly and statically to a hollow toroidal conduit, which houses optical wave guides, terminating at auxiliary connection ports, located on the exterior of the hollow toroidal conduit region, while hollow conduit support arms extend from the exterior conduit ring to a power conductor region, and integrate with optical connection ports located on static support stands, where the optical ports interface with a detachable and flexible fiber loop transducer, which surrounds an energized power conductor.

A system includes (1) a signal transmitter that includes (a) a radio frequency generator that generates a first radio frequency electromagnetic signal and (b) a first transducer that converts the first radio frequency electromagnetic signal to a surface wave mode signal imposed onto a powerline conductor at a first location in a first direction toward a second location along the powerline conductor, (2) a signal receiver that includes a second transducer located at the second location that converts the surface wave mode signal into a second radio frequency electromagnetic signal, and (3) an analysis subsystem that monitors a signal strength of the second radio frequency electromagnetic signal over time to determine whether a physical encroachment of the powerline conductor exists between the first location and the second location.

A passive optical network includes a central office providing subscriber signals; a fiber distribution hub including an optical power splitter and a termination field; and a drop terminal. Distribution fibers have first ends coupled to output ports of a drop terminal and second ends coupled to the termination field. A remote unit of a DAS is retrofitted to the network by routing a second feeder cable from a base station to the hub and coupling one the distribution fibers to the second feeder cable. The remote unit is plugged into the corresponding drop terminal port, for example, with a cable arrangement having a sealed wave division multiplexer.

The present disclosure describes a grommet formed of a polymeric material and adapted for bundling a plurality of discrete cables, comprising a main body having a generally cylindrical profile surrounding an interior cavity, the main body further having a length, a thickness, and a longitudinal axis; and a central member integrally coupled to the main body and located within the interior cavity of the main body, the central member extending generally parallel to the longitudinal axis of the main body. Methods of bundling cables are also provided.

A method for overhead transmission line installation includes tension pulling a transmission line over a path between a first support structure having a first mounting location and a second support structure having a second mounting location extending from the first mounting location to a first transition location on the second support structure, to a second transition location on the first support structure, and to the second mounting location. The transmission line is mounted at the first mounting location and the second mounting location. The mounting provides a slack portion of the transmission line between the first mounting location and the second mounting location. A portion of the slack portion is mounted proximate to the first mounting location or the second mounting location to provide an overhead transmission line extending between the first mounting location and the second mounting location and a remainder of the slack portion.

An overhead cable for the transmission of low-voltage and medium-voltage energy and digital signals, including a central fiber-optic cable, surrounded by a protective covering of the central fiber-optic cable and around such protective covering of such fiber optics by at least an aluminum alloy layer for the transmission of low-voltage and medium-voltage electric power or neutral wire and the covering thereof, where at least one aluminum alloy layer includes a 6101 aluminum alloy wire that has been heat treated, submitting the same to a temperature within a range of 260 and 300 C. and a treatment process for the aluminum alloy drawn wire.

Aspects of the present disclosure describe aerial fiber optical cable localization using distributed acoustic sensing (DAS) that advantageously may determine the locality of electrical transformers affixed to utility poles along with the aerial fiber optical cable as well as any length(s) of fiber optical cable between the poles. Further aspects employ survey manned or unmanned, aerial or terrestrial survey vehicles that acoustically excite locations along the fiber optical cable and associate those DAS excitations with global positioning location (GPS).
