The optical fibre ribbon of the present disclosure has one or more base access. The optical fibre ribbon of the present disclosure includes a plurality of optical fibres, a coating layer bonding the plurality of optical fibres, and a slit. The slit in the optical fibre ribbon is made between two optical fibres of the plurality of the optical fibres. The optical fibre ribbon has flat surface on top and corrugated surface in bottom. The optical fibre ribbon has a coating layer that is a layer of matrix material. The coating layer is made of single layer of matrix material.

A fiber optic cable terminal proximally terminates a stub cable carrying one or more optical fibers. The stub cable is structurally adapted to be advanced through at least a portion of a conduit by distally pushing a distal end of the stub cable from a location that is proximal to a proximal end of the conduit and without applying any pulling force at any location that is distal to the proximal end of the conduit.

An optical communication cable subassembly includes a cable core having optical fibers each comprising a core surrounded by a cladding, buffer tubes surrounding subsets of the optical fibers, and a binder film surrounding the buffer tubes. Armor surrounds the cable core, the binder film is bonded to an interior of the armor, and water-absorbing powder particles are provided on an interior surface of the binder film.

A process and system for making a water resistant cable component and water resistant cable components are provided. The water resistant cable includes a cable body including an inner surface defining a channel within the cable body and an elongate cable component located within the channel of the cable body. The cable also includes a contiguous layer of crosslinked super absorbent polymer surrounding the elongate cable component. The layer of crosslinked super absorbent polymer is formed by applying a liquid layer including a carrier material and an uncrosslinked super absorbent polymer pre-polymer material onto an outer surface of a component of the cable and then by crosslinking the super absorbent polymer pre-polymer while on the cable component to form a layer of crosslinked super absorbent polymer surrounding the cable component.

Embodiments of an optical fiber cable are provided. The optical fiber cable includes a cable jacket and a plurality of buffer tubes contained within the cable jacket. Each of the plurality of buffer tubes has one or more optical fibers disposed therein. A thin film tube is contained within the cable jacket and disposed around the buffer tubes, and an armor layer is contained within the cable jacket and disposed around the thin film tube. Superabsorbent polymer (SAP) powder is disposed between the thin film tube and the armor layer. The SAP powder includes at least 1 wt % of silica particles.

A fiber optic cable assembly comprises: a cable jacket; optical fibers carried within the cable jacket and extending beyond a first end of the cable jacket; a furcation body positioned on the first end of the cable jacket such that the optical fibers extend beyond the furcation body; and a pulling grip assembly having a proximal end selectively secured to the furcation body, a distal end opposite the proximal end, and an interior that contains fiber end sections. The interior of the pulling grip assembly is sealed off from an exterior of the cable assembly to provide sealed protection for the fiber end sections. The pulling grip assembly may include one or more air intake devices (e.g., cap or diaphragm) to harness energy from pressurized air used in a jetting process and thereby make it easier to pull the cable assembly through ducts.

The present disclosure provides ribbed and grooved sheath for optical fiber cables. An optical fiber cable (100) comprises one or more optical transmission elements (118) and a sheath (102) surrounding the one or more optical transmission elements (118). An outer surface of the sheath (102) has a plurality of ribs (104, 106, 108) and a plurality of grooves (110, 112) such that at least one groove has unequal groove width and/or at least one rib has unequal rib width. The plurality of ribs (104, 106, 108) is continuous and parallel on the outer surface. Alternatively, the plurality of ribs (104, 106, 108) is discontinuous.

An optical fiber cable includes: a core including optical fibers; a reinforcing wrap that surrounds the core; and a sheath that accommodates the core and the reinforcing wrap. The reinforcing wrap includes an overlapping portion. A first end portion of the reinforcing wrap overlaps a second end portion of the reinforcing wrap at a portion of the reinforcing wrap in a circumferential direction of the optical fiber cable in a cross-sectional view.

An optical fiber cable includes: a plurality of optical fibers or a plurality of optical fiber ribbons; a cable sheath inside which a plurality of the optical fibers or a plurality of the optical fiber ribbons are housed; and four or more tensile strength member units which are provided so as to be embedded inside the cable sheath, and in which two or more tensile strength members are paired with each other, in which the four or more tensile strength member units are respectively provided at locations facing each other with a center of the optical fiber cable interposed therebetween in a cross section in a radial direction of the optical fiber cable, and in which a cable outer diameter of the optical fiber cable is 6 mm or more and 16 mm or less.

A fiber optic thread assembly configured with a cumulative gap for mechanical responsiveness and protection from micro-bend damage. The assembly may be incorporated into a wireline or slickline cable for obtaining fiber optic readings of enhanced accuracy during an application in a well. The gap is uniquely tailored to allow for a natural reduction during deployment of the cable into the well, thereby providing the enhanced accuracy. However, the gap is also sufficient to help avoid micro-bend damage from the resulting mechanical responsiveness, which is attained upon deployment of the cable into the well.
