The transmission portion includes at a central position thereof, an optical fibre conductor and, at a radially outer position with respect to the optical fiber conductor, electrical conductors stranded around the optical fiber conductor. Preferably, the electrical conductors are grouped into sub-units which are stranded around the optical fiber conductor to provide a mechanical protection thereto.

The clamping device may include (1) a monitoring device for a powerline conductor, where the monitoring device includes (a) at least one detection component that detects at least one physical characteristic at a location of the monitoring device, (b) a transmitter that wirelessly transmits data indicating the at least one physical characteristic, and (c) a receiver that wirelessly receives data indicating the at least one physical characteristic from at least one other monitoring device, where the transmitter retransmits the data indicating the at least one physical characteristic from the at least one other monitoring device, and (2) a container that retains the monitoring device such that one or more of the at least one detection component is maintained proximate the powerline conductor. The clamping device clamps a fiber optic cable to the powerline conductor to restrict movement of the fiber optic cable relative to the powerline conductor.

An apparatus for controlling line guide of an automated material handling system, comprises: optical lines in which a side light emission optical fiber is installed in the whole section of a confluence of a plurality of lines of lines for moving the unmanned transport devices; a main confluence control device which is installed at the confluence, performs optical communication with the unmanned transport device through the optical line; and a sub-confluence control device which is installed in the unmanned transport device, performs optical communication with the main confluence control device through the optical line to report an entry state or a pass completion state for the confluence, and controls the unmanned transport device to perform an entry operation or a standby operation depending on the pass control signal.

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.

The disclosed system may include (1) a plurality of monitoring devices, where each of the plurality of monitoring devices is located at a different location along a powerline conductor and may include (a) at least one detection component that detects at least one physical characteristic at the location of the monitoring device along the powerline conductor, and (b) a transmitter that wirelessly transmits data indicating the at least one physical characteristic, and (2) a data injection device that (a) wirelessly receives the data indicating the at least one physical characteristic detected by the plurality of monitoring devices at the different locations along the powerline conductor, (b) transforms the data into an optical signal, and (c) injects the optical signal onto a fiber optic cable for transmission to a data collection subsystem. Various other systems and methods are also disclosed.

The present disclosure describes a grommet. The grommet includes a slot extending the length of a main body which provides an entry point for a cable to be inserted into an interior cavity, a plurality of flex retention members extending into the interior cavity configured to grip and secure the cable, and one or more grip enhancement features residing between an inner surface of the main body and the flex retention members. The grip enhancement features are configured to provide additional support to the flex retention members when a cable is inserted into the interior cavity. The grip enhancement features are coupled to or integral with a respective flex retention member and extend radially outwardly therefrom, and each grip enhancement feature is configured to engage or contact the inner surface of the main body when a larger diameter cable is received within the interior cavity of the grommet.

Hardware components for the termination and/or splicing of overhead electrical cables that have optical fibers associated with the cable. The hardware components enable access to the optical fibers for connecting to interrogation devices or for connecting to telecommunications equipment. The hardware components also enable the optical fibers to pass through terminations and splices without damaging the optical fibers.

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

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.

It is disclosed a process and an apparatus for manufacturing a figure of eight cable. An extrusion head has separate extrusion dies extruding in parallel a first and second outer sheath around a first and second core, respectively, so as to provide two separate cable elements having respective longitudinal axes laying in a first plane. While the outer sheaths are in a softened state, the cable elements are passed in parallel through a twisting die which causes their longitudinal axes to lay in a second plane forming a predetermined twisting angle with respect to the first plane. This twisting causes the outer sheaths to join together, thereby forming a figure of eight cable.
