To install a connectorized cable assembly, a cable terminated at a connector core is pushed through a duct. The connector core has a maximum outer diameter of no more than 5 mm to facilitate passage of the connector core through the duct. A plug body is mounted over the connector core after the connector core exits the duct. No intermediate assembly steps are performed on the connector core between being pushed through the duct and being inserted into the plug body.

The present invention discloses a logging encapsulated optical-fiber duct cable and a manufacturing method thereof. The encapsulated optical-fiber duct cable mainly comprises an external encapsulation layer. At least one armor tube is arranged in the encapsulation layer. An optical fiber protective tube is arranged in each armor tube. A filling layer is arranged in a space between the optical fiber protective tube and the armor tube. An optical fiber is arranged in the optical fiber protective tube. The manufacturing method mainly comprises four steps: pavement of the optical fiber and formation of the protective tube, formation of the filling layer, formation of the armor tube and formation of the encapsulation layer. The optical-fiber duct cable of the present invention has the advantages of large length, high strength, good temperature tolerance, small signal transmission loss, high transmission speed and synchronous transmission of multiple signals.

Downhole slickline cable including a polymer matrix having reinforcing fibers embedded therein. A plurality of integrity-sensing optical fibers are embedded within the polymer composite and extend along an axial length of the downhole slickline cable that enables slickline cable structural and mechanical integrity self-diagnosis. The cable may include energy transmission lines that include one or more integrity-sensing optical fibers.

A submarine device includes a main tail cable connected to a submarine cable, a first branch tail cable including a first group of optical fibers among a plurality of optical fibers included in the main tail cable, a second branch tail cable including a second group of optical fibers among the plurality of optical fibers, a branch member that couples the main tail cable to the first and second branch tail cables and including therein a through hole for branching the plurality of optical fibers included in the main tail cable into the first group and the second group, and a device main body including a first introduction part for introducing the first branch tail cable into the device main body and a second introduction part for introducing the second branch tail cable into the device main body. The branch member is fixed to the device main body.

Methods and apparatus for furcating fiber optic cables are provided. In some embodiments, a molded furcation tube array is generated by compressing rearward end portions of a plurality of furcation tubes together, and heating at least a portion of the rearward end portions to form a molded portion of the furcation tube array. Reinforcing filaments can be bonded into and/or throughout the molded portion. The molded portion can have internal chambers in communication with separate furcation tubes of the furcation tube array, in which optic fibers can be slidably retained, and the molded portion can be fixedly coupled to a housing, which in turn, can be coupled to a cable trunkline. Optic fibers can piston or slide longitudinally within the trunkline housing and molded portion.

A method for adhering a tubular body onto a surface that includes smoothing a portion of the surface to create a smoothed segment of the surface and applying a tubular body directly onto the smoothed segment of the surface after the smoothing of the portion of the surface. The surface at the smoothed segment is smoother than the remainder of the surface. The method further includes applying an uncured protectant onto the tubular body while the tubular body is on the smoothed segment of the surface and curing the uncured protectant into a cured protectant while the uncured protectant is on the tubular body on the smoothed segment of the surface. The cured protectant protectively encases and adheres the tubular body to the surface.

A method and reel design enables blowing cable from a reel into a mid-span access point within a cable conduit. The cable reel includes a central hub, a first flange located proximate one edge of the central hub, a second flange located proximate an opposite, second edge of the hub, and a third flange located between the first and second flanges. A continuous communications cable has first and second portions spooled on first and second reel sections. The technician inserts a first end of the communications cable into a mid-span opening in the conduit, so that the first end of the communications cable is directed toward the first end of the conduit. The first portion of cable is blown off of the first reel section. The technician inserts a second end of the communications cable into the opening in the conduit so that the second end of the communications cable is directed toward the second end of the conduit. The second portion of cable is blown off of the second reel section. Then, a mid-portion of the communications cable is separated from the third flange of the cable reel and resides proximate the opening in the conduit.

A stubbed terminal housing for fiber optic cable management in a utility vault or pedestal housing having a body portion, a cavity within the body portion, a plurality of fiber optic fiber ports extending from the body portion for entry and exiting of fiber optic fibers, and a mounting portion extending from the body portion for attaching the stubbed terminal housing to the utility vault or pedestal housing.

In an optical fiber network for transmitting optical signals in a robot having three or more joints connecting a plurality of links in series such that the links include two end links located at either end and intermediate links provided between the two end links, and the links connected by the joints are moveable relative to each other, a plurality of optical transceiver modules are provided on the links such that at least one optical transceiver module is provided on each link; and a plurality of optical fiber cables connect the optical transceiver modules in a ring; wherein at least one end of each optical fiber cable connecting the optical transceiver modules provided on different links is connected to one of the optical transceiver modules provided on the intermediate links.
